Comment by Tom Davey

The Ten Specifications n celebration of Environmental Science & Engineering Magazine’s 25th year of publication, we are pleased to reprint some of Founding Editor, Tom Davey’s editorial comments, many of which are as relevant now as when they were originally published….

The tall Stranger walked north along Toronto's University Avenue carrying a large staff. His flowing robes aroused little interest as he passed a group of students and faculty at the edge of the campus. Quaint dress is not unusual at the campus; in any event, the group was deep in discussion over the metaphysical aspects of the molecular structure of a gnat's kneecap. Vital issues such as this had kept some students at school until middle age.

The Stranger strode on, away from the campus, until he came to a marble palace rising into the sky, the home of Environment Ontario's Design Approvals Branch. As he entered, a knot of equipment suppliers staggered out, obviously broken men, crushed by forces beyond their control.

Grimly, the Stranger pressed on to the chamber where Design Approvals audiences were held. A dignified usher beckoned him forward imperiously. "Which manufacturer do you represent?" he demanded. But the Stranger was not to be intimidated.

"I have come on behalf of the Maker. He has heard the screams of anguish and torment from manufacturers and suppliers across the land.

From their clubrooms in Ottawa, Toronto and, yea, even in Hamilton, they have cried out and now their pleas have been heard. I now bring you The Ten Specifications."

With that he cast down a stone print-out. The first specification read: Equipment shall be innovative, based on sound engineering fundamentals.

The other specifications went on in the same vein, stressing ingenuity and progress.

The atmosphere was electric.

Some of the female scribes were so startled, they actually began scribing.

I

Even the consulting engineers present lost their composure momentarily and fingered their gold medallions nervously.

But the Man from the Ministry was a formidable figure also. He fingered the Ten Specifications thoughtfully, then a look of triumph flickered across his face.

"These are made in the Middle East. How do we know they will work in a cold climate? Moreover, we usually require at least 12 examples in Ontario. There are only 10 here. All Ontario treatment plants work well.

Indeed, we often set the pace for the rest of the country. Many people criticize but all say our plants are reliable."

"Maybe so," countered the Stranger, "but this reliability is too often achieved at the expense of innovation. Defensive engineering can maintain a proud tradition, but it will never permit the creation of new ones. It is true that your plants are re-

liable — but at what cost? Ardern, Lockett and Fowler discovered activated sludge at approximately the same time as the Wright Brothers first flew at Kitty Hawk. Where are the environmental equivalents of the space age?"

So went the classic confrontation.

The irresistible force against the immovable object.

Gradually, the Stranger could see that even he was getting nowhere. He left the building, parted the traffic on University Avenue with a wave of his staff, and walked on. And all over the Province, ledgers began filling with red ink as the true cost of this ministerial obduracy became apparent.

This editorial was published in Tom Davey’s book “For Whom the Polls Tell”.

Largest park in eastern North America established The Québec government is establishing the Parc national Tursujuq, which will become not only the largest national park in Québec, but also the largest in eastern continental North America.

The Parc national Tursujuq has an area of over 26 000 km2, equivalent to 54 times the area of Montréal Island. It is the biggest protected area dedicated to the conservation of sensitive species in northern biodiversity and the natural landscapes of great beauty on the eastern shore of Hudson Bay. Moreover, the addition of most of the drainage basin of the Rivière Nastapoka to the territory of the park enables Québec to achieve the goal of ensuring that protected areas cover the equivalent of 9% of the province.

Maggie Emudluk, Chairperson of the Kativik Regional Council, says that “the new park will protect not only the environment but also areas that are essential to the traditional ways of life of the Inuit and the Cree. A determined, united pressure group headed by our communities and regional organizations working with conservation

groups has fulfilled its mission, which will strengthen our confidence in the efficacy of the environmental protection regime established under the James Bay and Northern Québec Agreement.” www.mddep.gouv.qc.ca

Environmental benefits to be achieved with closing Holyrood A report by the Department of Natural Resources, Environmental Benefits of Closing the Holyrood Thermal Generating Station concludes that the replacement of the Holyrood facility with clean, renewable electricity addresses an environmental challenge for Newfoundland and Labrador.

“From 2000 to 2010, the Holyrood plant emitted an annual average of approximately 1.1 million tonnes of greenhouse gas emissions and an annual average of 11,610 tonnes of sulphur dioxide,” said the Honourable Jerome Kennedy, Minister of Natural Resources.

“Retiring this facility will address the environmental and health concerns expressed by residents of Conception Bay

who are impacted by Holyrood generation.”

Retiring the Holyrood plant helps meet Energy Plan and Climate Change Action Plan commitments and would help Newfoundland and Labrador and Canada meet their respective greenhouse gas reduction targets.

Developing Muskrat Falls and delivering clean and renewable hydroelectric power to both Labrador and the Island is the least-cost solution to meet growing electricity consumption. www.powerinourhands.ca

Windsorʼs tap water is going fluoride-free.

After six hours of debate Tuesday night, city councillors voted 8-3 to stop adding the chemical to the water supply — a practice Windsor began more than half a century ago. Fluoride opponents argued the practice is outdated, while supporters said it’s an effective way to fight tooth decay. The money saved by cutting out fluoride will go to oral health and nutrition education programs for the next five years.

BCʼs environment minister says Enbridgeʼs answers leave more questions BC Environment Minister Terry Lake has stated that Enbridge/Northern Gateway's answers at hearings into the proposed Northern Gateway Pipeline in Prince George are not providing enough detail to judge whether the company is living up to the promise to implement worldleading land-based spill prevention, response and mitigation practices.

"The responses that Enbridge/Northern Gateway representatives are giving our legal counsel are long on promises, but short on solid evidence and action to date," said Lake. "The company needs to show British Columbians that they have practical solutions to the environmental risks and concerns that have been raised.

So far, they have not done that."

During cross-examination by the Province, Enbridge/Northern Gateway representatives acknowledged that they are not able to say at this time how much of the pipeline, or areas where a spill might end up, would be within two kilo-

metres of a road and therefore accessible.

The company conceded that they have not yet determined the details of pipeline access, especially in remote regions, including high terrain areas.

The Province's cross-examination also revealed that Enbridge/Northern Gateway will not have a spill response plan finalized until six months before pipeline operations begin.

The government of BC has produced a video with Google Earth depictions of portions of the pipeline route in the province. The video shows an example, the Clore River, of the exceptionally challenging location and terrain involved with respect to mounting a timely and effective oil spill response. The video can be found at: ftp://ftp.for.gov.bc.ca/RNI/external/outgoing/NGP/.

Report claims NS residents enjoying cleaner environment Nova Scotians are enjoying a cleaner, greener environment as the province continues to meet, and exceed, its targets in the Environmental Goals and Sustainable Prosperity Act, according to a recent progress report.

Nova Scotia has achieved 14 of the 21 goals in the Act, and work continues to meet remaining targets. Highlights include: - Releasing a natural resources strategy in August 2011, that will guide the management of the province's biodiversity, forests, geological resources and provincial parks.

- Putting a wetlands conservation policy in place in December 2011 to protect important ecosystems by preventing the net loss of wetlands.

- Encouraging the cleanup and redevelopment of contaminated lands through new regulations announced in March.

- Ensuring all sewage treatment facilities in the province complied with guidelines for handling and treating septage by last December, fulfilling another legislated goal.

Work continues for solid waste, drinking water standards, wastewater management and renewable energy. The province also continues to work towards its economic prosperity targets through the Clean Technology Fund, communitybased feed-in tariff projects and signing agreements for the Lower Churchill Falls hydro project. www.gov.ns.ca

Canada Invests in Great Lakes nutrient initiative Peter Kent, Canada’s Environment Minister, has announced an important investment over four years to address the complex problems of recurrent toxic and nuisance algae, and near shore water quality and ecosystem health in the Great Lakes.

It will also help the Government of Canada to deliver on its commitments under the recently amended Canada– United States Great Lakes Water Quality Agreement.

marked primarily for remediation activities at approximately 1,100 contaminated sites, as well as the assessment of about 1,650 sites. Canada’s National War Museum was cited as a prime example of what can be done when contaminated land is managed properly. Before construction, the land at the location of the museum was considered to be a contaminated site. Now it is the cherished home of Canada’s military history.

Phase II of contaminated sites clean-up plan launched The Government of Canada has launched Phase II of the Federal Contaminated Sites Action Plan. It is expected to create 7,300 jobs in waste management and remediation across Canada, an equivalent of about 1,500 full-time jobs per year.

The Plan also supports skills development, training, and employment of Canadians, including Aboriginal communities and others who live in northern and rural areas.

Alberta to establish arm's-length environmental monitoring agency The government of Alberta says it will build the most comprehensive environmental monitoring program in Canada with the establishment of a new arm’slength environmental monitoring agency.

The new science-based agency will begin work in the oil sands region and will focus on what is monitored, how it’s monitored and where it’s monitored. This will include integrated and coordinated monitoring of land, air, water and biodiversity.

The initial focus of the new agency will be on the Lower Athabasca area, with the ability to expand to the rest of the province.

While the new agency is being established, environmental monitoring in the oil sands region will continue to be led through a joint federal-provincial program announced in February 2012. To date, that program has added new water quality sites on the Athabasca River and Muskeg River system; increased air monitoring by adding more sampling sites; and, improved bio-diversity monitoring to include all oil sands producing areas. Up to $50 million a year is being provided by industry in the region to support the joint federal-provincial environmental monitoring plan. www.environment.alberta.ca

Alberta creates single energy regulator Alberta’s Bill 2 - the Responsible Energy Development Act - will create a single provincial regulator for upstream energy resource activities involving oil, gas, oil sands and coal.

The new regulator will be a unified one-window approach that makes it easier to navigate the system. It will also be responsible for energy resource developments from initial application to reclamation.

Highlights of the Act include: • Higher fines for individuals and companies who break the law; • Voluntary registry for landowners to

register private surface agreements, which can then be enforced; • Increased flexibility for the regulator to receive and process applications in a way that supports effective and fair decision making. www.assembly.ab.ca

Troop Island, NS, to be protected Troop Island's natural wildlife habitats and important coastal lands will be protected for the benefit of Nova Scotians and future generations thanks to the combined effort of residents, community groups, Halifax Regional Municipality and the province. Troop Island is located on St. Margarets Bay, northeast of Peggys Cove.

St. Margarets Bay Stewardship Association and Nova Scotia Nature Trust spearheaded the work to raise the $820,000 needed to purchase and take care of the island. The province provided $150,000 towards the purchase price.

SK amends its EA Act Saskatchewan’s Environmental Assessment Amendment Act, 2010 was developed to ensure that economic development proceeds with adequate environmental safeguards to protect the environment and maintain public health. The amendments were made to align with the government's move to a results-based regulatory model, and to update and improve the environmental process.

To enhance environmental protection, financial penalties for non-compliance have been substantially increased, and potential for incarceration has been included as a strong deterrent. The Act also clarifies the courts' power to order repair or restoration of environmental damage. www.environment.gov.sk.ca

Latest update on tsunami debris An update to the British Columbia government's Tsunami Debris Management Plan is now available at www.tsunamidebrisbc.ca. The updated joint federalprovincial plan provides additional information and management protocols, including monitoring and surveillance of debris, collection and disposal of debris, and volunteer engagement.

The intent of the update is to engage communities in debris management and mitigate any impact that debris may have on B.C.'s shores in relation to public safety, the environment and the economy.

Some of the early concerns centre around the costs associated with recycling and land filling tsunami debris and the possibility of aquatic invasive species washing ashore along the coast. Although there have been no reports to date, an update regarding potential for aquatic invasive species is also underway.

As with any storm season, it is difficult to predict when, where, and how much debris will wash ashore in any given area. A recent report from the Government of Japan's Ministry of Environment suggests the majority of the continued overleaf...

PEI and fertilizer industry to improve agricultural sustainability The government of Prince Edward Island, the PEI Federation of Agriculture, the PEI Potato Board, and the Kensington North Watersheds Association signed a 4R Nutrient Stewardship Memorandum of Understanding (MOU) with the Canadian Fertilizer Institute (CFI) to link the province’s objectives for environmental action and agricultural sustainability with improved fertilizer use.

4R Nutrient Stewardship was established in cooperation with government, researchers, farmers and the public. The 4R approach ensures that nutrients are applied using the Right Source @ Right

Rate, Right Time, Right Place® through the adoption of beneficial management practices by producers to achieve economic, social and environmental sustainability.

PEI is the first Canadian province to sign a 4R Nutrient Stewardship MOU, but its potential does not end there. The 4R Nutrient Stewardship System was developed by the fertilizer industry to be flexible enough to be utilized anywhere in Canada and around the world to reduce emissions and provide an increasing profitability for farmers.

The MOU sets out specific elements of an agreement between the Government of PEI and the fertilizer industry, including a commitment by CFI to provide financial support of $150,000 over three years.

Funding announced to clean up part of Hamilton Harbour The Government of Canada has confirmed funding to clean up contaminated sediment at Randle Reef in Hamilton

Harbour.

The Randle Reef site contains sediment contaminated with persistent toxic chemicals and heavy metals, which were deposited from industrial operations that are no longer active. In 1985, Hamilton Harbour was identified as an Area of Concern under the Canada–United States Great Lakes Water Quality Agreement due to significant water quality impairments. While many improvements have been made to reduce pollution in the harbour, the contaminated sediment at Randle Reef remained a principal environmental challenge.

The estimated cost of the Randle Reef sediment remediation project is $138.9 million. In addition to the $46.3 million in funding from the federal government, the Province of Ontario has committed to provide $46.3 million, and $14 million is being contributed by the City of Hamilton, $14 million by U. S. Steel Canada and $14 million by the Hamilton Port Authority, as well as $2.3 million from the City of Burlington and $2 million from Halton Region.

Provincial grant supports lake monitoring The British Columbia Lake Stewardship Society (BCLSS) has been awarded a one-time $75,000 provincial grant to support its lake monitoring program, which contributes to the effective environmental stewardship of BC's water resources and ensures the collection of high-quality lake-monitoring data.

The BCLSS, with the support of the Ministry of Environment, has designed "The BC Lake Stewardship and Monitoring Program" to help educate the public on lake protection and provide communities with information on their local lakes. Program activities include water

sampling, training, education and technical support.

Through regular water sampling, local communities can better understand a lake's current water quality, identify impacts of human activities and monitor water-quality changes resulting from land development within watersheds. The lake-monitoring program also can assist with early detection of invasive species, such as the American bullfrog and zebra mussel that threaten BC's aquatic ecosystems.

CanadaĘźs emissions historically low Per capita greenhouse gas (GHG) emissions in Canada are at an historic low. The latest data indicates that Canadians emitted an average of 20.3 tonnes of GHG in 2010, the lowest level since tracking began in 1990. “The data collected shows that between 2005 and 2010, GHG emissions decreased by 6.5% despite an economic growth of 6.3%,â€? said Canada’s Environment Minister, Peter Kent. “These num-

bers demonstrate that the Canadian economy can grow without increasing GHG emissions levels.�

Environment Canada’s National Inventory Report, released in April 2012, highlights that, compared with 2005 levels, emissions in 2010 have declined in almost all sectors, including oil and gas and electricity generation. The Government of Canada's overall climate change strategy aims to reduce GHG emissions by 17% from 2005 levels by 2020. To achieve this goal, Canada is taking a sector-by-sector approach and has already taken action on two of Canada’s largest sources of emissions - transportation and electricity. www.climatechange.gc.ca

management responsibilities and technical expertise will come together to ensure a comprehensive and integrated approach to water management.

The plan will ensure the sustainability and quality of Saskatchewan's surface and ground water supplies, while protecting drinking water supplies from the source to the tap. The plan outlines seven goals: sustainable supplies, drinking water safety, protection of water resources, safe and sustainable dams, flood and drought damage reduction, adequate data, information and knowledge and effective governance and engagement.

The Water Security Agency will report annually on implementation of the Water Security Plan. www.wsask.ca

Water advisory issued for South Brook A non-consumption water advisory was issued in December for the Town of South Brook, Newfoundland, by the Department of Environment and Conservation and the Department of Health and Community Services, as the result of a failure of the tailings dam at the former Gullbridge mine site.

The main water supply for the Town of South Brook is located 20 kilometres downstream from the former Gullbridge dam, and a Class III scheduled salmon river is also in the area. South Brook is located on Route 380 of the Trans Canada Highway, west of Grand Falls-Windsor.

Officials are currently on-site to conduct

water sampling and evaluate the situation regarding long-term repair possibilities.

Water sampling will be conducted on an ongoing basis, and an update will be provided as more information becomes available. The advisory was lifted Dec 24.

Company ordered to remediate contaminated groundwater The Alberta government has issued an enforcement order to ensure that groundwater contamination on the site of a Bruderheim chemical plant is appropriately addressed.

Although the plant has not been in service since 2006, a functioning groundwater recovery system is required to ensure on-site contaminated groundwater is removed and treated. The recovery system in place has not been operational since approvals for the plant were transferred to Harold Jahn and his company, Heartland Industrial Park Inc., in 2011.

The enforcement order requires Mr. Jahn and the company to submit and implement a decommissioning and reclamation plan for the plant and a monitoring plan for the site’s groundwater. The order sets out due dates for each plan, beginning January 4, 2013.

When individuals or companies fail to comply with legislation, government has a range of options depending on the offence. Enforcement orders are issued under the authority of Alberta's Environmental Protection and Enhancement Act to ensure immediate action is taken to

correct a situation. www.environment.alberta.ca

Saskatchewan Environmental Code The Saskatchewan Environmental Code, which should be implemented soon, will be a legally binding, enforceable set of requirements to be followed by anyone conducting activities regulated by any of the acts that reference the code. It will provide directions and guidelines for projects, allowing operators in many situations to proceed in an environmentally friendly manner without unnecessary permits from the ministry.

The code is being developed collaboratively, bringing together experts with extensive knowledge in environmental protection, law and governance. The Code Development Committee, established in the summer of 2010, will provide advice to the Minister of Environment on the content of the code and its supporting materials. The actual writing of various Code chapters will be a collaborative process, done by eight Content Committees. These committees are made up of members from government, regulated communities and interested parties, all chosen for their interest in and knowledge of the particular subject area. The eight committees are: Air Management; Climate Change; Fish and Wildlife; Forestry; Industrial; Lands; Linear Activities; and Municipal. www.environment.gov.sk.ca

Cover Story

Gold mine cover structure improves environmental protection while increasing worker safety

L

ocated in northern Ontario, near the Town of Cochrane, Detour Lake has more than 15 million ounces of gold in reserves and an expected annual production of over 650,000 ounces. Detour Gold Corporation, a Canadian gold exploration and development company, is the developer. With production scheduled to commence in early 2013, this project is on track to becoming Canada’s largest operating gold mine.

Constructing a cover structure for their operation that also enabled them to house a conveyor needed to be done in a safe, environmentally responsible and cost-effective manner. Detour Gold’s requests were threefold: ensure worker safety by minimizing the amount of dust created by the stockpile; minimize the release of dust into the environment; manage the amount of material awaiting transport to the mine’s ore processing facility.

Selection process In early 2011, Greatario Engineered Storage Systems responded to a bid request by Detour Gold for their stockpile containment solution. BBA’s structural engineers, the Detour Gold engineering team, AMEC, Greatario and CST Covers met to discuss specifications of the bid.

Partnering with their parent company, CST Covers, allowed Greatario to offer a customized ‘turnkey’ containment solution for the mine. Following review of the proposal and site visits to other CST bulk storage domes, the contract was awarded to Greatario in December, 2011. Greatario assumed the role of general contractor and installer of the dome. CST Covers provided engineering services, and manufactured and supplied the dome.

Key factors leading to Detour Gold’s decision to employ Greatario’s dome solution for the site included: • Capability to customize the build to meet project specifications. Covers are designed around a bulk storage facility’s specific clearance requirement, stockpile configuration and bulk handling equipment.

• Structural design of the CST domes including aluminum joints requiring no

onsite welding.

• Aluminum is corrosion resistant, offers larger clear span cover capabilities and design flexibility, resulting in less installation time, labour and equipment.

• Greatario’s aluminum construction helps to eliminate fugitive particulate emissions, comply with clean air regulations, manage dust and protect stored material from degradation by the elements.

• Low capital cost.

• The dome can be removed and redeployed once the mine is decommissioned.

Construction A typical design/build would be ‘tower build technology’, which means the dome is built from the inside-out. The inner frames and poles are constructed and raised by a pole crane. However, as the existing conveyor at Detour Gold eliminated the opportunity to use this technology, an outside-in cover construction method was used.

Outside frames and panels were constructed on the walls of the structure. The frames and panels were then constructed inward until the dome was complete. Man lifts and cranes were used as the dome rings were completed. The construction

team built one complete ring at a time and then moved up to the next ring. A total of 25 rings was assembled.

In total, 3,363 beams were constructed into aluminum gussets to form the structure. Greatario’s team built the dome as deliveries from CST Covers arrived on site. As the prefabricated beams slide easily into aluminum gussets and hold securely, the assembly process requires no welding of the dome itself, which was a huge advantage. This precise assembly process allowed the construction team to assemble the dome under various weather conditions. The finished frame was then clad with over 2,240 aluminum sheets.

The finished stockpile dome is 97.5m in diameter and 52m high, which is the largest dome that Greatario has built and the largest aluminum geodesic dome in Canada. It is designed to withstand snow loads and wind speeds typical for the area.

Material is transported from the dome to the mine’s ore processing plant via an existing underground tunnel.

Water Treatment

Using layers of protection analysis in water safety assessments

By Roland A. Bradshaw, George L Illaszewicz, Mark Keller, Alvin Beier and Amanda Beattie

L

ayers of protection analysis (LOPA) is a powerful analytical tool for assessing the adequacy of protection layers used to mitigate environmental and process risks in engineered water supply and sanitation systems.

In pursuing their mandate of providing good and safe drinking water, water system operators and asset owners have to work continuously towards developing and maintaining the trust and confidence of their customers. Provision of safe and reliable services requires a robust approach that identifies and prioritizes all risks and supports decision-makers in taking the correct course of action.

This need for systematic and systemic assessment and management of public health risk has been documented in the Bonn Charter and the World Health Organization’s Guidelines for Drinking Water Quality, which introduces the concept of Drinking Water Safety Plans based on source-to-tap risk assessments.

Applied to operating and maintaining water supply systems, LOPA provides a procedure for assessing the adequacy of independent protection layers (IPLs) used to mitigate environmental and process risks.

These IPLs include independent treatment units, standard operating procedures and incident response procedures.

LOPA is used for the review of technical systems’ reliability and the review of organizational resilience under trying conditions. It provides a systematic approach to identify and prioritize maintenance and optimization programs that, once implemented, maximize the overall level of service of the infrastructure.

Dramatic incidents in recent years, such as the E. coli and Campylobacter jejuni related outbreak in Walkerton, Ontario, the outbreak of cryptosporidiosis in North Battleford, Saskatchewan, and various Cryptosporidium outbreaks in the U.K. and in Milwaukee, Wisconsin, have led to an increased emphasis in the water sector on explicitly assessing and managing risks.

22 | January 2013

Staff engaged in operations and incident management must have a strong sense of the primary mission of the organization.

Literature increasingly suggests three main root causes for water system failures: physical inadequacy and failure of assets and equipment, failure due to human interaction, and failure within organizational decision-making processes.

The introduction of a socio-technical system’s perspective broadens the scope for risk assessments. A methodology is required that considers water system risks not only related to tangible assets, but also human factors, organizational processes — even organizational culture.

Such integrity assessments help ensure that water systems deliver the desired outcome in terms of functionality and quality, and also ensure that technical and organizational risk mitigation measures are available and functional.

These meta-assessment processes straddle risk, environmental, maintenance and safety management processes, and are composed of methodologies to aid the identification and management of hazards and their respective risks.

LOPA provides such a model, enabling both the review of technical reliability and organizational resilience under trying conditions, as well as the opportu-

nity to learn from failures. As a semiquantitative technique, LOPA also fills the gap between subjective qualitative techniques, such as hazard and operability studies (HAZOPs) or process hazard analyses (PHAs), while requiring fewer resources than a full quantitative risk assessment. It offers a conservative, rational and systematic method for assessing the suitability and sufficiency of protection layers present within the system.

Developing LOPA for the water sector LOPA builds upon process hazards analysis techniques, applying semi-quantitative measures to the evaluation of the frequency of potential incidents and the probability of failure of the IPLs. Originally developed for the process industry, LOPA has been utilized to identify and develop appropriate safety integrity levels (SIL) as per the requirements of safety standards such as IEC 61508, IEC 61511, or ANSI/ISA 84.00.01-2004. LOPA provides a methodology that can be used to identify and assess safeguards across physical, human, information and intangible assets.

Water Treatment Within the water sector, treatment units, standard operating procedures and incident response procedures can all be considered independent protection layers, as long as the following criteria are met: Specificity. An IPL is capable of detecting and preventing or mitigating the consequences of specified, potentially hazardous events, such as a runaway reaction, loss of containment or an explosion.

Independence. An IPL is independent of all the other protection layers associated with the identified potentially hazardous event. Independence requires that the performance of one IPL is not affected by the failure of another IPL or by the conditions that caused that IPL to fail. Most importantly, the IPL is independent of the initiating cause.

Dependability. The protection provided by an IPL reduces the identified risk by a known and explicit amount.

Auditability. An IPL is designed to permit regular periodic validation of the protective function.

The following case study of the application of LOPA as an assessment technique for the water sector consisted of a retrospective review of a series of incidents that occurred in a large water utility considered representative of typical utilities. The LOPA methodology was applied to investigate the organization under “trying conditions” to assess the effects that IPLs had in generating organizational resilience during the incident situations.

IPLs considered relevant for reliable organizations operating under trying conditions were: • A strong organizational culture of reliability.

• Staff competencies via continuous learning and intensive training.

• Effective and varied patterns of communication.

• Adaptable decision-making dynamics and flexible organizational structures.

• System and human redundancy.

Organizational reliability A strong organizational culture of reliability is a necessary bulwark against the failures that can have catastrophic consequences. Staff engaged in operations and incident management must have a strong sense of the primary mission of the organization. Operations managers, engineers and operators need www.esemag.com

to share a common system of beliefs and perceptions where water safety is concerned. Failure scenarios should be well understood and reflected in the monitoring program of water system assets.

Constant vigilance and concern for water safety and reliability need to dictate the behaviour of staff. This is particularly relevant to field operators, but also to control room staff who must act with alertness, attentiveness and care in monitoring the healthy operation of the water

supply system. Employees are encouraged to take responsibility, particularly where problems are identified and immediate corrective action programs are required.

Staff competency The review of incidents revealed that staff generally managed incidents and restored the system to safe operation with competence. Staff training is extensive and focuses on the skills required for continued overleaf...

Water supply systems depend on duty standby arrangements or excess capacity to isolate failed assets and compensate for their loss.

maintaining a safe system. Operators are required to obtain a licence to operate a water supply system. Training and certification are vitally important, but the content of that training is critical, including raising awareness of the substantial public health responsibility carried by operational personnel. In-house and onthe-job training are also important components for ensuring staff competency.

Performance of each task is evaluated with respect to formal rules, generalized guidelines and standardized frameworks.

These are expressed in standard operating procedures (SOPs), risk assessments and method statements. The emphasis is on identifying potential sources of failure and implementing appropriate preventative actions.

Communication of incidents to staff helps relevant personnel understand the vulnerability of the system. This communication also helps the water utility to learn by studying failures, near failures and mistakes. Failures in one part of the organization can be used as a means of studying the failure susceptibility of the organization as a whole. Incident review meetings are designed to highlight and prompt cross-organizational learning in other parts of the business.

Effective and varied patterns of communication Organizations with strongly developed IPLs create information-rich environments. Effective communication allows a complex system to become more under24 | January 2013

standable, predictable and controllable.

During an incident, inter-personnel communication is designed as both bottom-up and top-down to ensure the rapid flow of information through the hierarchy of the incident management team.

Rapid dissemination of information helps the organization respond to an incident with corrective action on a timely basis, thus preventing unnecessary escalation of the incident into an emergency.

Adaptable decision-making dynamics and flexible organizational structures Incident documentation was studied to assess the ability of the organization to adapt its organizational structure to respond to the needs arising during an incident. It was found that in the majority of the incidents, the organization effectively reduced the impact on customers and reinstated normal operations.

Incident assessment also examined decision-making during incidents. Incident management efforts require “good decision-making� to significantly and pro-actively reduce the impact on customers and to reinstate normal operations as soon as possible. As a general rule, incident management efforts have to avoid poor judgment, poor decisionmaking, and the inability to be adaptable.

Overall, an organization needs to demonstrate that decision-making under trying conditions effectively draws the necessary and correct conclusions from the data available to the incident manage-

ment team. This suggests that the quality of the decisions made is a reflection not only of the data availability during an incident, but also of the competence of the decision-makers involved in an incident.

System and human redundancy Typically, water supply systems depend on duty standby arrangements or excess capacity to isolate failed assets and compensate for their loss. During incidents, system redundancy needs to be available to reduce or avoid customer impact. Designing redundancy for a system can also be counterproductive, however, as backup functions can increase technical complexity, conceal errors and discourage individuals from performing their specified tasks.

Therefore, the need for redundancy has to be investigated as part of planning incident management response procedures. In this review it was found that the availability of system redundancy successfully mitigated or reduced the impact on customers in an overwhelming number of incidents.

Human resource management practices that support reliability Organizations with strongly developed IPLs select suitable and skilled candidates, aiming to match, as closely as possible, the complexity of the work environment. An incident manager has to be able to cope with uncertain situations and demonstrate rational decision-making under trying conditions.

The incident manager has to be able to communicate effectively with the staff and stakeholders involved in incidents.

The manager also requires a good understanding of the entire water supply system, while drawing on the expert knowledge of the incident management team.

All of these dimensions have been observed to contribute to the effective management of water safety and reliability.

Each dimension is important individually, but it is when acting together as a coherent configuration that incidents are effectively managed and future risks can be sufficiently understood and planned for.

PEO helping those affected by the repeal of the industrial exception By Michael R. Price

W

ith the proclamation of the repeal of the industrial exception anticipated early in 2013, Professional Engineers Ontario (PEO) has proactively developed a transition plan and support program to assist those who will be seeking licensure to prepare for the new legislation.

The repeal of the industrial exception, which is section 12(3)(a) of the Professional Engineers Act, will improve workplace safety and business efficiency by ensuring individuals are licensed by PEO if they plan, design, compose, evaluate, advise, report or supervise professional engineering work on machinery or equipment used for production for their employer in their employer’s facility.

Since the repeal received Royal Assent on October 25, 2010, PEO has held public meetings with industry in close to 80 per cent of the province and across a broad range of manufacturing sectors. These meetings have included one-on-one discussions with employees and employers on the specific scope of this change.

As a result of these consultations, PEO council passed a regulation in September 2012 that would give employers who file a compliance plan with PEO prior to proclamation of the new requirement for licensure, up to one year after proclamation to be in compliance.

As well, PEO council extended its Financial Credit Program, which waives the licence application fee, to all employees who apply for a licence on or before the proclamation date and who are named in their employer’s compliance plan. PEO will also assist these employees through the one-year compliance period by providing application and Engineering Intern Program (EIT) seminars. It will also administer professional practice exams at their job sites.

To take advantage of this support program, and in anticipation of the imminent proclamation date, compliance plans and new licence applications must be submitted to PEO on or before March 1, 2013.

The industrial exception to the require-

ment to hold a licence to take responsibility for engineering work has been in place since 1984 and only in Ontario. Repealing this exception aims to improve workplace safety and business efficiency, as well as create a national framework for licensure.

This means all Canadian jurisdictions will have the same requirements to hold a licence in order to be responsible for professional engineering.

Under the Occupational Health and Safety Act and its Regulation 851, a prestart health and safety review (PSR) conducted by a professional engineer is required prior to starting up equipment within an industrial establishment. Soon, the Professional Engineers Act will be consistent with the requirements and intent of the PSR and will bring a professional engineer into the equipment development cycle. With licensed professional engineers in place from the beginning of the process, the safety of Ontario

workers will be further assured and operations will be more productive.

“Integrating health and safety at the design stage and before operations begin is a cost-effective and proactive way to prevent workplace illness and injury. The benefits are numerous. They include direct savings from minimizing retrofitting, less downtime and replacement of equipment; savings in workplace insurance claims due to fewer illnesses and injuries; and, most important, maintaining productivity, health and safety in the workplace.”

Water Distribution

Microtunneling used for railway portion of Halton’s newest watermain By Joe Proietti and Nathaniel Andres

H

alton Region has retained R.V. Anderson Associates Limited for the design and contract administration of a trunk watermain in Burlington and Oakville. Construction is currently underway for the 4km long watermain that will support population growth and add redundancy to the Region’s distribution network.

The Zone 3 Watermain project includes several challenging obstacles, including the trenchless crossing of railway tracks in an area with mixed soil conditions. More specifically, geotechnical investigation revealed fill overlaying clayey silt, dense sandy silt/silty sand, dense gravelly sand, and completely weathered shale.

In addition, the project was made more complicated by an artesian groundwater condition where, depending on the installation method, extensive pumping over a relatively long duration was anticipated.

This pumping had the potential to contribute to settlement, as the purging of water creates voids in the subsoil matrix.

The design of the railway crossing for the 900mm diameter watermain included a 1500mm diameter casing pipe. Jack and bore is a method typically employed with success in such instances. However, the possibility of encountering hard shale made this option less preferable, particularly given the rail authority’s requirement to keep the face of the casing pipe at least one pipe diameter ahead of the auger during installation. Likewise, it was expected that pipe ramming could encounter similar issues.

It became evident that the operation would require extensive thought and consideration before selecting the ultimate installation method, which was provided by Ward & Burke Microtunneling Ltd. With the influx of contractors specializing in the installation technique, microtunneling has become increasingly prevalent as a solution to the challenging subsurface conditions encountered in southern Ontario.

Microtunneling involves the use of an

unmanned tunnel boring machine (TBM).

The TBM uses slurry pressure, in conjunction with the jacking force to maintain tunnel face stability in a closed system.

This prevents soil and water from entering the tunnel, thereby minimizing soil loss and ground settlement. Slurry pressure is balanced against the in situ stresses acting on the TBM and is consistently monitored during construction. This pressure matching strategy prevents over-excavation and enables tunneling without the need for dewatering, which not only helps to prevent settlement but also to manage costs.

Also among the benefits of the microtunneling concept is the ability to operate in varying ground conditions. A variety of cutting faces at the head of the TBM can be used effectively for sand, silt, clay, gravel, rock and other mixed face conditions.

Affixed to the cutting head are steering cylinders that allow the operator to control the line and grade of the tunnel. A laser located in the jacking shaft marks a target that is mounted inside the TBM. The operator uses information exchanged between the units to ensure accurate orientation and location of the cutting head.

The TBM bores through the subsurface, leaving an annulus of 30mm all around the jacking pipe. Every six pipes, a length with a prefabricated port is installed through which bentonite is

pumped into the annular space. It fills the void around the pipe, temporarily supporting the surrounding soils and minimizing friction to lessen the required jacking forces. At the completion of the crossing, the bentonite is forced out of the annular space, while being replaced by grout to prevent ground settlement.

Excavated material enters from the face of the TBM into a crusher chamber where it is ground into smaller pieces. In order to create a slurry, water is pumped into the crusher chamber, so the mixture can be transferred to the control container at the ground surface. To avoid soil and groundwater loss, the operator monitors the amount of slurry taken with a flowmeter inside the container.

Once in the separation system, a centrifuge extracts the solids that can then be trucked away for landfill disposal. Water that remains is pumped back down the shaft to the cutting head and the crusher chamber. The amount of recycled water is also metered to provide a completely monitored process.

In the case of the Zone 3 Watermain, a 1500mm diameter reinforced concrete jacking/casing pipe was installed. The pipe was provided by Tracey Concrete and meets 140D loading specifications.

While Tracey, a European concrete pipe manufacturer and supplier, has met the needs of various Ontario municipal projects, local manufacturers are currently de-

Water Distribution veloping their products to meet the requirements of microtunnel jacking pipe.

Installation of the tunnel entry and exit shafts using the caisson technique was effective and controlled water with minimal dewatering. In general, 2.5 metre high, cast-in-place, reinforced concrete rings were poured at grade. The concrete rings were sunk into place in segments by excavating from inside the walls until the shaft reached full depth. At this point, open-bottomed cylinders remained, forming the footprint of the shafts. but not preventing the ingress of groundwater.

Tremie concrete was used for the base of the shafts. Now, with a completely enclosed structure at the entry and exit points, water remaining in the shafts was pumped out, which was the last time groundwater pumping was required for the trenchless crossing.

The TBM entry shaft, located at the low end of the tunnel, was converted to a drain chamber for the watermain following installation of the jacking pipe. This eliminated the need for a separate manhole excavation.

There were several benefits to the mi-

crotunneling process that were realized during the installation of the Zone 3 Watermain. Where a permit to take water was originally thought to be necessary, no dewatering was required throughout the tunneling process. Moreover, limited pumping was necessary for the shaft installation. Next, minimal settlement was reported in the vicinity of the railway tracks. Additional settlement at the entry shaft was promptly controlled with the use of bentonite and, ultimately, grout.

Lastly, despite the varying soil types, there were no technical issues as the TBM advanced.

When considering if microtunneling is a suitable trenchless technology for a project, due regard should be given to the potential constraints. Besides geotechnical design considerations, the tunnel length may be a limiting factor. Microtunneling is typically considered for lengths between 50 and 500 metres, although longer lengths have been completed. Shorter installations are often cost-prohibitive.

Also, the amount of working room available may negate the use of this technology. The Zone 3 Watermain required

an entry and exit shaft of 7 metres and 5 metres diameter, respectively. The operator control container, separation unit, and temporary stockpiling required additional space on the ground surface adjacent to the entry shaft. A typical microtunneling setup has a larger footprint than jack and bore, but substantially smaller than that required for conventional tunneling.

The unmanned TBM makes this trenchless installation technique a relatively safe alternative that not only provides reliability to minimize ground settlement but also alignment and grade of critical infrastructure.

Biological desulphurization of landfill biogas

By Alisa Wiebe, Hadi Husain and Derek Webb

A

biogas desulphurization process is providing very high removal efficiencies at a landfill site in Québec. Despite highly variable concentrations and low winter temperatures, the system, from Biorem, has achieved an average removal efficiency of 97% and has consistently maintained outlet hydrogen sulphide concentration below target. As a result, the customer has realized a significant cost reduction over the previously used chemical scrubbing process, and the site environment has improved.

The biological desulphurization process offers many benefits over scavenger media and chemical scrubbing processes. No media replacement is required, and only small amounts of nutrients are needed. The operation is simple and inherently safe, and the payback period for the capital investment is relatively short.

Trends in biogas management Landfills containing organic and construction wastes generate biogas throughout their useful life and for a significant period following closure. Rates of biogas generation and composition depend on many factors, including temperature, gas withdrawal rates, the characteristics of the waste being treated, and landfill layout. The gas is withdrawn using wells Landfill gas flow Temperature Composition: Methane Carbon dioxide Oxygen Inlet H2S concentration

duce power from biogas. Regulatory and environmental pressures, as well as government incentives such as Ontario’s Feed in Tariff program, have improved the economics of power generation from biogas, despite the recent drop in natural gas prices.

Biogas contains many impurities, which, if left untreated, result in high power generator maintenance costs. In particular, siloxanes — organic compounds of silicon — are of great concern as they form silica deposits in engines and turbines. Manufacturers of this equipment specify maximum acceptable loading rates, as well as the maximum acceptable hydrogen sulphide loading rate. Regardless, hydrogen sulphide concentration should be reduced upstream of the siloxanes removal system to avoid interference.

Conventional methods for biogas desulphurization include reaction with scavenger media to retain hydrogen sulphide as iron sulphide, or chemical scrubbing, which uses a mixture of caustic and bleach to oxidize the hydrogen sulphide to sulphuric acid. Other methods such as condensation and adsorption have also been used in some instances.

Reaction with scavenger media is the most common process, due to its simplicity of operation, despite frequent media change-outs, high pressure drop and high operating cost. However, as the concentration of hydrogen sulphide increases, so does the cost of media replacement and capital.

Biological desulphurization The biological desulphurization process uses biotrickling filtration (BTF), which is similar to the process used for removing hydrogen sulphide from sewage plant exhausts.

But there are important differences. Due to the absence of oxygen in biogas, air or oxygen must be added to the gas stream to promote bio-oxidation. Chemi-autotrophic, acidophilic thiobacillus bacteria use energy from hydrogen sulphide oxidation for growth, while producing sulphur and sulphuric acid according to the following reactions: continued overleaf...

Air Pollution 2H2S+ O2 → 2S+ 2H2O 2S + 3O2+ 2H2O → 2H2SO4 H2S + 2O2→ H2SO4 Optimum reaction pH is in the range of 1.5 – 2, although the reaction continues at a pH as low as 0.5. Nutrient addition is required for cell growth, but the proportions are very small, almost onetenth of those required for a typical aerobic process.

In BTF systems that treat hydrogen sulphide-bearing air, the objective is complete oxidation to sulphuric acid. In biogas systems, depending on the specific plant, it is often preferable to minimize sulphuric acid and maximize sulphur production. For example, Biorem designs its systems to limit conversion to sulphuric acid to approximately 20%, and the balance to sulphur. The key reason is that complete oxidation requires a higher level of air addition, which increases the nitrogen content of biogas and lowers its heating value. Increasing the ratio of sulphur to sulphuric acid production also increases reactor productivity.

However, an undesirable consequence of maximizing sulphur production is continuous deposition of sulphur on the biotrickling filter media. Media must be selected carefully to promote self-cleaning. In addition, provisions should be made for in situ media washdown to prevent reactor plugging.

The Biorem biological desulphurization process is managed by controlling oxygen content in the treated gas. Residual oxygen concentration is used to adjust air feed rate. This is highly effective as it provides good control regardless of changes in biogas flow or composition.

Important process parameters that are monitored include hydrogen sulphide concentration in the treated biogas, reactor pressure drop, biogas temperature and sump pH. In larger systems, automatic purge, based on the sump pH value, may be used. However, in most cases, manual monitoring and purge adjustment are adequate, as landfill biogas composition does not change rapidly.

Economics of biological desulphurization A biological system does not need media replacement, and the use of chemicals is relatively small. This provides a major cost advantage over the scavenger media system. Media replacement is a 32 | January 2013

recurring cost in the scavenger system, and is estimated at $6 per 10/kg of hydrogen sulphide removed. This is generally valid for capacities in the range of 500 – 2,000 m3/h and hydrogen sulphide concentrations of 300 – 4,000 ppmv.

The cost of capital and power are extra, and the power costs are important to consider, as the pressure drop may be as high as 0.5 psi. Recurring costs in a biological treatment system include nutrients and power. However, these costs are very low, since a biofilm process

A biological system does not need media replacement, and the use of chemicals is relatively small. typically uses relatively small amounts of nutrients and the pressure drop through a BTF is only 1 – 8 inches of water column. Thus the power cost of a scavenger system exceeds the cost of power and nutrients in a biological process.

However, the capital cost of a biological treatment system is higher than a scavenger media system. For a large system with total hydrogen sulphide removal capacity of 150 kg/day, the payback period for a biological system compared with a scavenger system is

only 30 – 60 days. This increases as system capacity and hydrogen sulphide concentration drops, but remains less than three years for a 5kg/day hydrogen sulphide removal system. For smaller systems, a scavenger media system becomes increasingly cost-effective.

Case study - Québec Since 1985, Veolia Environmental Services has operated a construction and demolition (C&D) waste landfill in Québec City. Over the last 20 years, recycling of C&D waste has increased, resulting in diversion of waste from landfills, hence increasing the landfill’s life. The landfill closed in 2009, when it reached its capacity of over 4,000,000 m3 of C&D waste. But production of biogas is projected to continue for at least another 10 years.

Drywall material is one of the main constituents in C&D waste and the source of a majority of fines. The drywall contains gypsum, a soft mineral consisting of hydrated calcium sulphate.

Under anaerobic conditions in the landfill, the sulphur-based compounds in the gypsum are converted to hydrogen sulphide and other reduced-sulphur compounds that are highly odorous.

Due to the proximity to urban neighbourhoods, as the landfill grew in size, gas collection wells were installed to collect methane gas and odorous compounds. Unfortunately, the volume of the biogas was small, and the methane content of the gas was less than 35%.

This made a biogas conversion to energy option uneconomical. Therefore, the primary reason for landfill gas collection and treatment was odour control.

Initially a chemical scrubber in combination with a woodchip biofilter was used to treat sulphur compounds in the biogas. The dual-stage treatment system reduced the hydrogen sulphide content from approximately 1,000 ppm to less than 50 ppm. As the chemical scrubber aged, efficiencies decreased and main-

tenance requirements increased, so an alternative was required.

In December 2010, Biorem started its BTF system. This system is specifically designed for the high concentrations of hydrogen sulphide found in biogas and consists of a compact, vertical tower design utilizing high-efficiency media with compound-specific bacteria.

The biological desulphurization system requires a continuous flow of recirculated water and a constant supply of

nutrients. It is operated under acidic conditions at approximately 86°F (30°C).

Biogas characteristics are presented in Table 1. Biorem system design objectives and features are presented in Table 2.

Conclusion Figure 1 presents removal efficiencies as measured during the last two summers.

Average removal rate is 97%. Design target for maximum hydrogen sulphide in the treated gas is 50 ppmv, which has been consistently achieved since startup.

The Biorem biological desulphurization process has been proven to be a cost-effective technology for biogas treatment.

Treatment systems are available in a wide range of capacities and hydrogen sulphide concentrations.

Biological treatment is particularly attractive at hydrogen sulphide loading rates of 5 kg/day and higher.

Leak Prevention

Bridging the gaps in water and wastewater containment systems

W

ater and wastewater treatment facilities are exposed to hazardous and costly leaks, unless containment vessels have linings that will “bridge” structural cracks and resist harsh chemicals.

Although water and wastewater treatment vessels are engineered to be foolproof, leakage of these vessels due to mechanical or chemical influences can pose a serious threat to the health and safety of workers, the public and the environment. In addition to those hazards, leaking containment systems also result in unplanned down time and diminished capacities, accompanied by time-consuming, expensive and recurring repairs.

There are several choices of products that are designed to protect against leaking or spilling of the aqueous materials in primary and secondary containment structures. Yet many of the most popular products offer only limited protection, and may fail due to a variety of chemical and mechanical challenges.

These challenges are due to the wide array of chemicals that are found in industrial water and wastewater treatment operations and attack the surfaces they are in contact with. These include hydrogen sulfide, sodium hydroxide, sulfuric acid, sodium hypochlorite, chlorine, and numerous other industry-specific and harsh chemicals.

Mechanical issues include abrasion or erosion of primary containment linings due to solid contaminants, and cracking of concrete substrates used for primary containment vessels. On steel substrates, linings often lack high permeation resistance, which will cause the lining’s topcoat to display blisters. These blisters are symptoms that linings are failing, due to molecular vapor transmission.

Secondary containment dikes are required to enclose leaks and spills for three days, but damage to the lining from the spill of chemicals can compromise the dike’s integrity. UV rays and weather can cause concrete to move and crack, and degrade some polymers, causing the same problems. So, the choice of material to 34 | January 2013

line primary and secondary containment vessels and dikes can make a major difference.

The elastomeric bridge One solution is an engineered elastomeric lining system that can be applied to primary and secondary containment structures. This lining is designed for its long service life, ability to “bridge” joints and cracks in concrete, imperviousness to UV light and harsh chemicals, and ease of installation. The Elasti-Liner system from KCC is a line of engineered elastomeric products that is applied by brush or roller to concrete substrates and directly over expansion and control joints.

Polymers are cross-linked and act like coiled springs that expand and also contract as concrete moves.

“In the past, we used 100 percent epoxy coatings on our secondary containment structures,” says Brian Peroni, corrosion control specialist at Florida Power and Light. “Epoxy might work well enough for some primary containment applications, but for concrete structures it can be inadequate. In concrete structures live cracks will occur, and because epoxies are a rigid coating, they tend to crack right along with the concrete.”

To overcome the problems of leaks resulting from cracked concrete in primary and secondary containment structures,

Peroni uses and recommends Elasti-Liner elastomeric liner. “The product has great crack bridging properties,” he explains.

“That’s why it is so effective for us. We don’t have to worry about cracks in the concrete and we don’t have a lot of maintenance.”

Clarifiers at power plants are another example of containment structures where cracking can be a serious problem. These primary containment vessels are often designed with metal sidewalls resting on a concrete base. In an attempt to prevent leaks when the concrete base cracked, the concrete is often reinforced with grout.

However, when the concrete moves or cracks, the grout seal can also fracture.

One of the main benefits in using this elastomeric lining on containment and other concrete structures is that concrete joints are simply taken care of by the lining overlaying the joint, so joint problems are completely eliminated. The lining is great at bridging cracks up to one-eigth inch because of the way it is engineered.

Polymers are cross-linked and act like coiled springs that expand and also contract as concrete moves.

The elastomeric liner exceeds the tensile strength of concrete. If you deliberately tried to pull the liner off the concrete, you would have to exceed 500 PSI in pulling strength. So, this elastomericbased lining is well bonded to concrete, no matter what the concrete does.

Rethinking the risks and benefits of fluoridation

By Sheldon Thomas

A

mong the responses to my article ‘What are the long-term effects of fluoridation?, published in the September/ October 2012 edition of Environmental Science & Engineering Magazine, it was correctly pointed out that I am neither an expert on public health or a medical doctor. I am, instead, a student of drinking water quality and of the infrastructure systems that deliver finished water to Canadians. I can assure you, however, that I have been a very good student for 38 years.

For 36 of those 38 years I accepted fluoridation as just another step in drinking water production. Then I viewed a tape of Dr. William Hirzy, senior scientist at the USEPA’s Risk Assessment Division Office of Pollution Prevention and Toxics, addressing a U.S. Senate Committee on Environment and Public Works. Dr. Hirzy was representing the USEPA Union of Scientists, and their collective plea was for Congress to impose an immediate moratorium on water fluoridation.

Let me highlight something that is a matter of record. The USEPA administration does not condemn fluoridation, but the scientists and health professionals in its employ do - all 1,500 of them. The USEPA scientists who so strongly object to fluoridation include seasoned biochemists, pharmacologists, teratologists and toxicologists.

Dr. Hirzy pressed for a fluoridation moratorium because his research, and the studies of many others, strongly indicated that ingested fluoride ion, once entered into the bloodstream, does harm to both soft and hard tissue. I recommend that every open-minded drinking water professional watch Dr. Hirzy’s video. (http://www.youtube.com/watch?v=hRLz 4a7lDVM) There is an assumption that health professionals and medical doctors offer the only trustworthy opinion on the health effects of fluoridation. I suggest that the most trustworthy opinion would be one offered by a competent researcher who has made it his/her mission to understand how chronic exposure to low concentra36 | January 2013

tions of fluoride ion can affect humans and animals. As a water professional, I want to hear from that person.

There is a list of well-known health organizations, the List of 901, which has been cited for years by those who promote fluoridation. The List, however, is losing membership as organizations rethink their support of fluoridation. The National Kidney Foundation2 and the National Research Council3 are two organizations that have recently struck their names from the List. In 2011, The International Academy of Oral Medicine and Toxicology, in a letter to the CDC, stated that it would never go on the List4. Even the Oral Health Division of the Centers for Disease Control and Prevention (CDC), although remaining on the List, has significantly adjusted its assessment of fluoridation. The CDC has twice conceded (in 1999 and 2001) that the best use of fluoride in preventing dental caries is to apply it directly to the teeth, via toothpastes or fluoride gels.

Toothpaste has 25,000 times more fluoride than saliva fortified by injested fluoridated water.5 Since the List has been so instrumental in directing opinion on fluoridation, let’s have a look at some of its signatories.

The World Health Organization

(WHO) does favour fluoridation. But what is often ignored by proponents is the WHO’s precautionary caveat that water fluoridation programs should not be entered into unless the municipality/water authority has conducted prior tests on residents to establish their total daily fluoride intake from all sources of food and beverage and environmental exposures. If fluoride intake is already at, or beyond, a level deemed protective of teeth, adding it to drinking water would be an excessive measure. How many fluoridating municipalities test their citizens in this manner before agreeing to start or to continue fluoridation? I am sure that the WHO would prefer that its full statement be known.6 Health Canada is prominent on the List. Health Canada literature suggests that fluoridation is just a topping up of the natural fluoride that is already present in source water. That would be true if we were topping up natural calcium fluoride concentrations with additional calcium fluoride. The chemicals commonly used to deliver those additional fluoride ions are actually synthetic silicofluorides, the most favoured for use being hydrofluorosilicic and hexafluorosilicic acid. These continued overleaf...

Water Supply chemicals are normally classified as regulated category 1 toxic wastes7 but they become environmentally acceptable, and fit to ingest, the moment that they are relabeled as water treatment ‘products’.

Health Canada states that these, and other silicofluorides, are safe and effective for use as fluoridating agents. But upon what does Health Canada base those assurances?

In response to an information petition submitted to the Office of the Auditor General in 2008, Health Canada had to reveal that it “does no research on silicofluoride chemicals”8. So, Health Canada cannot speak to the safety of silicofluorides from any results of in-house testing.

Health Canada relies, instead, on NSF International (NSF), a private industry consortium, to test, certify and assure that silicofluoride chemicals are safe for use in drinking water. Unfortunately, if you read its literature closely enough, you’ll note that NSF does not offer that assurance at all.9 NSF examines water treatment chemicals and additives to attest that they meet already established government health

guidelines, and certifies them ‘appropriate for use’ if they do.10 An important distinction here is that NSF does not certify any chemical to be ‘safe for use’. In its own carefully worded disclaimer in the foreword of ‘NSF/ANSI Standard 60’, NSF does not presume to tell anyone what to do with the chemicals that it certifies.

Nor does it hold itself responsible for the performance of any of the chemicals that it certifies.11 Chemical ‘safety’ is a measurement of performance.

Normally, NSF requires manufacturersupplied toxicological testing of all drinking water treatment chemicals and additives before granting Standard 60 certification10. One is left to wonder why NSF, still missing the good-to-go paperwork on silicofluorides, has not pressed harder for the mandatory toxicology tests.

While awaiting those tests, NSF has adopted a different approach to its certification of silicofluoride chemicals. Using hydrofluorosilicic acid (HFSA) as an example, NSF has chosen not to examine the chemical compound as a single product.10 Instead, NSF simply identifies all of the combined constituents of HFSA, in-

cluding the co-contaminants commonly found within the acid, and examines them separately for government guideline compliance. If none exceed the MACs or MCLs established by Health Canada or the USEPA, NSF certifies HFSA as appropriate for use.

There are some who maintain that HFSA toxicology studies are unnecessary.

They subscribe to the belief that, as soon as HFSA is fed into drinking water, it ‘dissociates’ completely and reliably into its major components, silica and fluoride ions12. That theory can best be described as hopeful. In 2001, the USEPA was called before Congress and, under oath, had to admit that it had no credible evidence that HFSA fully dissociated in municipal drinking water13. After five decades of fluoridation, the USEPA could find nothing to defend the use of HFSA. At the same hearing the USEPA also revealed that it had “no information on the effects of silicofluorides on health and behaviour.”13 I’ll end examination of the List by discussing the promotion of fluoridation by the Canadian Dental Association (CDA).

Water Supply The CDA joins its voice to 44 other dental organizations on the List of 90 to announce that fluoridation is both safe and effective. But, unfortunately, there is nothing in dental training that positions any dentist, or dental organization, to speak authoritatively about the interaction of the fluoride ion with soft and hard tissue throughout the body.

For any dental association to claim that fluoridation is safe, it must be able to supply proof that highly-reactive ingested fluoride ions do not cause harm to any part of the complicated human organism on their way to the teeth. There are, on average, 60,000 miles of blood vessels14 and 30 trillion red blood cells that sustain every nook and cranny of the human body. The CDA is asking us to believe that the fluoride ion, a known enzyme killer15, is going to leave untouched all of those blood cells16 along a journey the equivalent distance of 2.5 times around the planet.

As for the benefits of fluoridation, that so out-weigh the harms, the CDA could tell you about a $3.7 million study conducted by the National Dental Research

www.esemag.com

Institute (NDRI) in 1986. It was designed to measure the effect of fluoridation on dental caries reduction after 40 years of drinking water fluoride ‘adjustment’.

Dental researchers selected 84 different school districts, spread across the United States, comparing dental caries of children in fluoridated communities with those in non-fluoridated communities.

It is worth pointing out that there are some long-established scientific/medical organizations that are not on the List.

They include the Nobel Institute, the Pasteur Institute and the National Academy of Science. These celebrated scientific icons offer a markedly different assessment of the safety and benefits of fluoridation.

For any dental association to claim that fluoridation is safe, it must be able to supply proof that highly-reactive ingested fluoride ions do not cause harm.

They compared the dental records of 39,207 school children of the same age group. The data revealed that fluoridation didn’t work. In what was anticipated to be a landslide victory for fluoridation, the data revealed that there was no statistical difference between dental caries recorded in fluoridated communities and dental caries recorded in non-fluoridated communities. There are several other large studies that reveal very similar findings to the NDRI study.17

The National Academy of Science (NAS) conducted a landmark review of all of the available literature on fluoridation, publishing a report in 2006 titled, ‘Fluoride in Drinking Water: A Review of the EPA’s Standards’. It took a balanced (not for, not against) panel of selected researchers 3.5 years to wade through and analyze the subject material. The panel concluded that there was strong evidence that linked fluoridation to a multitude of continued overleaf...

Water Supply human degenerative conditions and diseases.18 The panel sent a clear and urgent message to health authorities and governments to fast-track studies to further examine water fluoridation’s links to cancers, hypothyroidism, Alzheimer’s-like symptoms, skeletal degeneration, and childhood IQ and behavioural deficits.

In spite of the findings of the NAS (a health advisor to governments for 150 years), Health Canada still maintains that there is no credible evidence that water fluoridation causes any harm other than mild dental fluorosis, something that it classifies as a ‘cosmetic condition’.19 Let’s talk a little more about the chemicals at the heart of all of this. Health Canada appears to struggle to properly classify fluoridating chemicals. It has tried to brand fluoride as an essential nutrient20, when in fact the body ticks along quite nicely without it.21 In 1979, the US FDA found the nutrient claim so absurd that it ordered government documents to cease making the statement. Then Health Canada tried to convince us that fluoride was a ‘dietary fortification’. That doesn’t fly either, as a body with no biological need for fluoride does not need to be for-

tified with more. Health Canada seems to have settled on classifying silicofluoride chemicals as water treatment chemicals.

I have real difficulty accepting silicofluorides to be treatment chemicals. There is no apparent role for fluoride in the conversion of raw water into finished drink-

We produce drinking water that meets all of the requirements of the Safe Drinking Water Act in Ontario without having to add a drop or a crystal of silicofluoride chemical. So, in the treatment of drinking water, how do fluoridation chemicals ‘treat’, exactly?

The answer (and not a very good one)

is found in the AWWA ‘Water Dictionary’, Second Edition, page 670. Look up ‘water treatment’, and you will find: (1) The act of removing contaminants from source water by the addition of chemicals, filtration and other processes, thereby making the water safe for human consumption. (2) The act of adjusting water quality to satisfy the requirements of any end use.

Fluoridation chemicals do nothing to fulfill the first part of the definition, but they slip nicely into the second part. Silicofluorides are added to drinking water singularly for their alleged ability to reduce dental caries. They are used in an attempt to suppress the disease of dental caries. They serve as a medication. They act as a drug. That is their end use.

Water professionals should be asking themselves what, if anything, part (2) of the definition has to do with part (1). Part (2) appears to have been inserted into the definition to add credibility to the use of chemicals that have no role in the production of potable water. Also, “to satisfy the requirements of any end use” is language that calls for some serious explanation.

How many end uses do authorities envision for the drinking water supply?

Water Supply Water professionals should also be reminded that NSF states openly that as many as 15 different contaminants could be in any shipment of HFSA. It’s noteworthy that NSF does not require the removal of any contaminant. It just requires that they not exceed anyone’s MAC, or MCL. Shipments of HFSA are accompanied by a manufacturer-supplied Certificate of Analysis that frequently lists lead and arsenic as present in the acid, along with their concentrations. Lead is a probable carcinogen22, and arsenic is an established carcinogen.23 Ontario Drinking Water Quality Standards require that the concentration of arsenic in finished water not exceed 1 ppb. Health Canada stated, in 2006, that every effort should be made to keep arsenic out of drinking water.24 Unfortunately, adding HFSA after treatment often introduces arsenic, contrary to the Health Canada recommendation. But, with arsenic getting diluted in drinking water by about 240,000 to 1, is it really that big of a deal? Let’s look.

NSF states that arsenic is five times more common than any other contaminant of HFSA. And it’s usually there in the highest concentration of any25. NSF calculates that the arsenic typically found in HFSA will dilute down to just under 0.5 ppb in drinking water25. So, clearly, the use of HFSA can add approximately .5 ppb of arsenic.

So, how scary is half a part per billion of arsenic? That’s enough to cause a fatal cancer in 1 out of 10,000 who drink fluoridated water. The cancer estimates are the work of the National Resources Defense Council (NRDC)26, using data provided by the National Academy of Science, data which the NAS earlier extracted from the USEPA’s own database. I found these estimates disturbing enough to contact the NRDC directly last summer to learn more about its February 2000 Report, "Arsenic and Old Laws". The NRDC still stands firmly behind its report, and the cancer estimates are based upon a standard, scientifically-accepted modeling methodology.

How do drinking water professionals react to this kind of information? Do we dismiss it because it’s too shocking to possibly be true? Do we dismiss it because all of those on the List claim such things cannot be so?

Faced with continuing debate over the merits of water fluoridation, civic-minded councilors struggle to identify the right path.

Water treatment operators and managers are highly-skilled, licensed and dedicated to the provision of high quality drinking water. They are the stewards of safe drinking water, working at the very start of the process. Trained as they are, they are also less likely to be influenced by the old, and dangerous, fluoridation promotions that crumble in the light of emerging evidence and modern scientific methodology. Councilors hear regularly from the List. They need to hear more from the Water Stewards.

Disinfection

Mixed oxidants show disinfection benefits for municipalities

M

unicipalities in Canada have been using mixed oxidant chemistry on a trial basis and have found that mixed oxidants are a viable alternative to gas and hypochlorite disinfection.

The most significant advantage over gas chlorination or hypochlorination is an ability to maintain chlorine residuals further along the water distribution system, due to better biofilm removal. Other noted advantages of mixed oxidants are ease of operation with self-cleaning electrolytic cell on-site generators, fewer safety issues in comparison to gas chlorination, and lower costs compared to purchasing hypochlorite in bulk.

For compliance with provincial requirements, the mixed oxidant solution is measured and dosed as free available chlorine (FAC) and therefore the same disinfection requirements for gas chlorination and hypochlorination will apply.

How on-site generators work While many different types of on-site generators (OSG) are available, there are a number of components that almost every OSG uses (see Figure 1).

Water coming into the OSG first goes through a softener, after which it is split into two lines. One line feeds directly into the electrolytic cell, while the other is used to fill the brine tank. The brine tank stores a concentrated salt solution, prepared by having an excess of salt in the tank so that the solution is near-saturated brine. It is then injected into the softened water stream entering the electrolytic cell.

When the dilute salt solution is inside the electrochemical cell, a current is passed through the cell, producing the oxidant (sodium hypochlorite or other oxidants) solution. After leaving the electrolytic cell, the oxidant solution is stored temporarily in the oxidant tank and is then metered into the water moving through the treatment process. Hydrogen gas is also produced inside the electrolytic cell, and the hydrogen is removed from the cell and oxidant storage tank through vents.

The electrolytic cell, where the oxi42 | January 2013

dants are actually produced, is central to the OSG. Electrolytic cells consist of two electrodes, the anode and cathode, arranged so that both make contact with the mixed water and brine solution. When the OSG is activated, a voltage is applied to the cell so that current flows through the cell, causing chemical reactions to take place at the surfaces of both electrodes that eventually produce the disinfectants.

The overall chemical equation for reaction of salt (NaCl) and water (H2O) to form sodium hypochlorite (NaOCl) is: [1] NaCl + H2O —> NaOCl + H2 Oxidation reactions are carried out at

the anode where two chloride ions (Cl-) are stripped of one electron each to produce chlorine gas: [2] 2Cl- —> Cl2 + 2eDepending on the physical and working parameters of the cell (e.g., electrode to electrode spacing, cell applied potential, etc.) it is also possible to produce oxidants other than chlorine, which can provide enhanced removal of microbiological contaminants from water, and other benefits. After the chlorine gas is produced, it dissolves in water to produce hypochlorous acid (HOCl), in the same way that bulk chlorine gas from cylinders acts:

Disinfection [3] Cl2 + H2O —> HOCl + H+ + ClChlorine production is balanced by the reduction reactions that occur at the cathode where water (H2O) is converted into hydroxide ions (OH-) and hydrogen gas (H2): [4] 2 H2O + 2e- —> 2 OH- + H2 During electrolysis, hydrogen gas is produced as bubbles that must later be removed from the OSG and oxidant storage tanks to prevent gas buildup. The hydroxide ions produced at the cathode then react with the hypochlorous acid produced at the anode, producing the hypochlorite anion (OCl-), which is charge balanced with sodium cations (Na+) that originally came from the salt: [5] HOCl + OH- —> H2O + OClTypically, the pH of oxidants that OSGs produce is around 9. The addition of these solutions often does not alter the pH of the water that is to be treated. Overall reaction: [6] NaCl + H2O —> NaOCl + H2 Mixed oxidants Mixed-oxidant solution (MOS) is made from exactly the same process and feed stock as 0.8% sodium hypochlorite

Figure 4: DBP reductions with mixed oxidants.

MOS are responsible for enhanced biocidal efficacy (demonstrated on a variety of micro-organisms), as well as enhanced behaviour in several chemical processes important in water treatment.

Figure 2 shows one example of the superior biocidal efficacy of MOS compared to sodium hypochlorite/bleach (NaOCl). There are several results published in the peer-reviewed literature that have demonstrated this superior efficacy.

Analytical method limitations include FAC interference. A major obstacle to de-

termining additional oxidant species present in MOS is the lack of analytical techniques for differentiating oxidants.

Researchers continually improve oxidant analyses for FAC, ozone (O3), hydrogen peroxide (H2O2) and chlorine dioxide (ClO2). Almost invariably, however, each of the methods is based on the total oxidizing capacity of the solution being analyzed and is readily subject to interferences from the presence of other potential oxidizing agents or intermediates from associated chemical reactions. This is

especially true for analyzing additional oxidants in the presence of FAC. By the 2000s, a growing body of evidence for H2O2 and/or other reactive oxygen species in MOS had emerged. The chemical and biocidal behaviour of MOS, coupled with potentials measured at the anode of the electrolytic cell, suggest the presence of other oxidants including reactive oxygen species (ROS).

ROS are present in solutions of nonchloride brines electrolyzed under electrolytic conditions similar to those for producing MOS. More recent research on the chemical species present in MOS using non-chloride brines has provided evidence that stronger oxidants than chlorine (likely ROS) are present in the solution. O3, H2O2, and hydroxyl free radicals (.OH) were detected at the point of generation.

The longevity of each of these species in MOS is still not established, although that of O3 and .OH is expected to be short — milliseconds to seconds. This explains why no O3 is detected in the bulk MOS. Literature data suggests that at higher pH levels, such as those found in produced MOS, H2O2 has the potential to last hours

The benefits that customers have experienced with mixed oxidants over the last 15 years include: • Enhanced residual.

• Reduction and disinfection byproducts - reduced total trihalomethanes (TTHMs).

• Improved taste and odour (T&O).

• Biofilm control.

• Micro-flocculation — reduction of coagulants at surface WTP. • Improved oxidation, e.g., for arsenic, iron, manganese.

Enhanced residual Figure 3 provides evidence of municipalities using chlorine gas or bulk hypo and experiencing typical chlorine residuals seen at the end of the distribution system. These water municipalities made a switch over to mixed oxidants.

Cedar Knox, Nebraska, and North Table Mountain, Colorado, were able to reduce their dose and achieve a higher chlorine residual with mixed oxidants. In these cases the municipalities were dealing with biofilm issues.

Engineers often ask how long it takes to see these types of reductions.

It all depends on the complexity, size and severity of biofilm.

A Montana State University study confirmed that MOS is able to penetrate the polysaccharide film that biofilm uses to attach to the distribution system walls. In all these instances there had to be a public awareness program as well as a flushing program to remove the particulate from the distribution system so it did not go into people’s homes.

Reduction of disinfection byproducts The maximum contaminate level (MCL) for trihalomethanes is 80 parts per billion. Figure 4 shows several communities that were close, exceeding, or very close to TTHM maximum contaminant limit while utilizing chlorine. When they made the switch to mixed oxidants they were able to reduce concentrations to below or further below the 80 parts per billion MCL. This is all attributed to the removal of the biofilm.

When they were able to remove the biofilm, they were able to reduce the amount of chlorine that was being injected into the distribution system. With the reduction in chlorine, there is less of a reaction to the organic material that is in the water, which creates the disinfection byproduct. www.esemag.com

Figure 6: Biofilm in the distribution system with chlorine.

Engineers often ask how long it takes to see these types of reductions. It all depends on the complexity, size and severity of biofilm, as well as the size of the distribution system. In Greenfield, Iowa, the amount of disinfection byproduct formation at both the treatment plant and the distribution system was reduced over a three-month period from the time of the first injection of the mixed oxidant. (See Figure 5.)

Diana Water Supply Corporation in Texas provided Figure 6.

There were simultaneous main breaks in an area where sodium hypochlorite was still being used and another area using mixed oxidants. In the area with sodium hypochlorite, the biofilm is still evident in the pipe distribution wall. This confirms the study of biofilm done by Montana State University.

Wastewater Treatment

Unique wastewater solution for remote mining and energy exploration camps

T

he harsh and remote locations of camps serving the natural gas and oil industries mean basic infrastructure such as water and wastewater presents unique challenges to both residents and operators.

Wastewater infrastructure for these camps can take on many forms and, in some cases, yield benefits beyond just the treatment of wastewater. Over the past couple of years, two similar but uniquely different wastewater systems have been installed and placed into operation at remote camps in Wyoming and Alaska.

Natural Gas Camp Rock Springs, Wyoming Southern Wyoming’s harsh open plains are the home for many oil and natural gas workers. In 2009 a new camp outside of Rock Springs, Wyoming, became operational. It generates 20,000 to 40,000 gallons of wastewater per day.

The treatment system chosen was an AeroCell® fixed film media filter, manufactured by Quanics, Inc. and installed below grade at the site.

The media filter consists of pre-engineered and constructed fiberglass modules containing open cell foam cubes.

The patented open cell foam media has been researched and utilized for effective wastewater treatment since the early 1990s. As with all media filters, the media itself serves to allow microbial attachment for biological breakdown of the wastewater constituents, as well as physical filtration of organics.

Wastewater from the camp is pumped via a grinder lift pump into a series of three 40,000 gallon fiberglass pretreatment tanks outfitted with effluent filters.

Because the sewage is ground into a fine slurry, additional tanks were required to allow adequate settling of finely ground solids. Wastewater flows via gravity into a fourth 40,000 gallon fiberglass recirculation tank. This tank is equipped with four duplex pump systems.

Pretreated effluent is alternately dosed into two banks of four AeroCell treatment modules. Each module contains 400 ft3 of open cell foam media.

After passing through the open cell foam media, 80% of the effluent is returned back to the recirculation tank to undergo further treatment. The remaining 20% is discharged through multiple tablet feed chlorinators, where it is super chlorinated to 50 ppm. Treated and chlorinated

water is then pumped into large vertical storage tanks for reuse at the facility.

The AeroCell system was designed to achieve secondary effluent quality and has been in continuous operation for over three years. During this time, effluent samples have been collected and analyzed for BOD, TSS and fecal coliform on a weekly basis by a third party. Results of these weekly samples show an average effluent value for BOD of 21 and TSS of 8. Fecal coliform values have consistently been non-detectable.

Oilfield Camp on the North Slope of Alaska The “North Slope” of Alaska is one of the harshest environments in the world in which to survive, let alone work. Temperatures can reach -70 degrees F and wind chill factors can reach -100 degrees F. In such an environment, equipment must be reliable, simple to operate, and easy to maintain.

A new camp being constructed in 2009 was in need of a wastewater treatment system. It would discharge to an environmentally sensitive area that is predominantly tundra and wetlands.

Therefore, effluent would have to comply with the State of Alaska Department

of Environmental Conservation’s secondary treatment standards for BOD (30 mg/L), TSS (30 mg/L), and fecal coliform bacteria (40 Col/100mL). In addition, the system had to be energy efficient, easy to operate, reliable, and require little operator skill and oversight.

The wastewater system selected would need to be capable of handling 4,000 gpd of domestic strength wastewater generated from the camp and be completely self-contained and mobile. The Synergy™ system from Quanics was selected to meet both these requirements. The heart of the system is the treatment modules containing open cell foam media.

That technology is installed inside a standard 53’ trailer, which is insulated, plumbed, wired and heated before leaving the factory. The mobile nature of the trailer allows the system to be set up and shut down quickly and easily, so that it may be relocated.

Tanks are installed inside an insulated and heated ATCO structure.

which consists of a 2,400 gallon aerated equalization tank, followed by four 2,400 gallon settling tanks (with effluent filters) connected in series. All are installed inside an insulated and heated ATCO structure. Effluent filters with progressive filtration were installed in each settling tank. As the wastewater flows through the series of tanks, settleable solids, floating solids, and some suspended solids are removed through a process of clarification and filtration.

Effluent from the primary treatment tank trailer is transferred to the Synergy trailer, where secondary treatment is achieved.

The Synergy trailer consists of 6,000 gallons of recirculation/pump tankage and two Aerocell trickling filter units.

After passing through the open cell foam media, 80% of the effluent is routed back to the recirculation/pump tanks for further treatment. The remaining 20% flows

The heart of the system is the treatment modules containing open cell foam media.

Design consisted of a primary treatment trailer (equalization tank, and a series of settling tanks with effluent filters) followed by a 5,000 gpd Synergy mobile wastewater treatment trailer. The design was reviewed and approved for construction by the State of Alaska Department of Environmental Conservation.

Wastewater from the camp is first pumped to the primary treatment trailer, www.esemag.com

through a chlorination/de-chlorination system and then discharges directly to the tundra. During periods of low usage, such as at night, a valve on the 20% discharge line closes and 100% of the effluent is routed back to the recirculation/pump tanks, thus “super treating” the effluent.

The camp was moved to two different sites during the drilling season. Operators were extremely pleased with the op-

eration and ease of use of the Synergy system. There is no need to return sludge, waste sludge, monitor dissolved oxygen levels, or run settleometer tests.

All that is required is a periodic check of the tablet chlorination system. In short, virtually no operator skill is required.

The average sampling result for the months of March and April was 14.4 mg/L for BOD and less than 10 mg/L for TSS. The highest BOD level tested (four tests) was 14.9 mg/L. It should be noted that the system was hydraulically and organically overloaded by 20-40% during this sampling period. In spite of this, it performed flawlessly.

Summary The Wyoming and Alaska camp wastewater systems utilize the same fixed film media filters as the heart of the treatment process. However, each system was engineered and configured based upon the climate, mobility requirement and discharge parameters for the individual site. The unique nature of these types of camp facilities requires engineers, camp operators, regulatory officials and equipment manufacturers to work together to develop and implement viable and unique wastewater solutions.

Wastewater Treatment

New device provides wastewater aeration in collection systems By Vahram Mkrtchyan, Tariel Mkrtchyan and George Katsarov

T

he objective of a recent study in Armenia was to improve sewer system operation, while reducing influent BOD. For this purpose, studies were performed in wastewater systems with piping of various materials and various diameters.

Results have shown that biomembrane is formed on the walls of the pipes and in inspection and cleaning chambers, manholes and service connections. It was observed that, when the wastewater flow velocity is 0.3 – 2.0 m/s, and the temperature is within the range of 17 – 21 C, the biomembrane thickness reaches 2-10 mm.

It is fully formed during 70-75 days, after which its thickness does not change much.

Throughout the whole wetted perimeter, a thicker biomembrane is developed in the zone of the free flow surface where, as a result of free aeration (air contact), the quantity of dissolved oxygen is relatively higher than at the bottom of sewers, where the biomembrane thickness is minimum.

This is a result of abrasion by sand and other solid contaminants moving in the lower layers of the flow.

The thickness of biomembrane depends mainly on wastewater flow velocity, as well as dissolved oxygen, temperature and other elements. However, in the case of high velocities, the upper layers of biomembrane fail and are removed with the wastewater flow. The greater the velocity, the smaller is the biomembrane thickness.

The studies have also shown that the biomembrane that is fully removed from the pipe wall, due to high flow velocity, will recover itself within 20 – 30 days.

Biomembranes formed in the pipes are close in physical nature to those formed in biofilters. They promote biodegradation and mineralization of organic matter during wastewater move-

The highest oxygen demand for treatment is in the sewer, where wastewater has the highest concentration of contaminants.

Therefore, rapid oxygen consumption and deficit of oxygen takes place in the sewers thanks to the pre-aeration due to air penetrating the network. Therefore, it is possible to use the collection network as a pre-aeration system, implementing preliminary artificial aeration methods within it. As a result of network pre-aeration, wastewater will be enriched with dissolved oxygen, and the BOD of wastewater influent to the treatment plant will be decreased. This will result in reduction of

treatment facilities’ sizes and operation costs. Also, network ventilation will improve and pipe corrosion will be reduced.

Studies showed that in wastewater collection systems it is possible and feasible to apply mechanical pre-aeration methods. For this purpose, a simple mechanical aerator has been developed, and it is being used in wastewater networks in Armenia. The model is being patented.

It is a simple disk aerator, which includes a number of vertical disks of various diameters fastened on a metallic

www.esemag.com

horizontal spindle. At the ends of the metallic spindle there are bearings, which allow rotation. The disks are circular and are made of corrosion resistant materials.

The diameter and quantity of the disks are selected depending on the diameter of the sewer. (See Figure 1) The disk aerator is installed in the inspection/cleaning chamber/manhole at a height that will not interfere with free flow of wastewater. The aerator disks rotate thanks to the dynamic pressure of the wastewater and the friction force formed at the surfaces of the disks. Rotation speed depends on the size of the disk surface submerged and wastewater flow velocity.

The size of the aerator is determined by the maximum and minimum fullness of the sewer, in order that it is always submerged.

During rotation, the disks provide mixing of free air and wastewater. This results in an increased level of dissolved oxygen in the wastewater. Over time, the rotating disks are also covered with biomembrane, becoming disk biofilters. According to initial assessment of the aerator performance tests, BOD removal in the collectors

was around 5 – 7%. Currently, studies are being performed for assessment of the aerator’s impact on other wastewater parameters, including efficiency of initial treatment.

The main advantages of this aeration system are: no electric power is required; easy operation and maintenance; no rapidly wearing parts; can operate at different liquid levels. The equipment can also be installed on the wastewater treatment plant’s discharge pipe, to provide post treatment.

This aeration equipment can be efficiently used not only in regular municipal wastewater systems, but also in some long sewers, where wastewater movement velocity reaches 2.3 m/s.

Odour Measurement

New Canadian technology allows cost-effective, accurate in-field odour measurement

A Scentroid SM100 being used to analyze odours from a sample bag.

T

he evaluation of odour emissions has always been a challenging and costly problem for industries such as wastewater treatment, agriculture, oil refinery and chemical manufacturing.

In Canada, the standard procedure for predicting ambient odour concentration is to contract specialized environmental consultants to take sample gas emissions from multiple locations and transport them to a laboratory for analysis by a dynamic dilution olfactometer. This procedure is often very costly and can be a logistical nightmare, due to the 24-hour expiry of samples caused by odour degradation. Therefore, plant operators may perform odour assessments infrequently 50 | January 2013

and only when required by law or due to complaints by the local population.

Historical measurement techniques The need for cost-effective self-assessment was realized more than 50 years ago. This led to the development of the first ambient odour measurement device, which was a rectangular, clear plastic box containing two activated carbon beds on each side. There are six odorous air inlet holes on one end of the box for six different dilution values (2, 7, 15, 30, 170 and 350). The opposite end of the box contains two glass nostril tubes for sniffing.

The principle is simple. When the operator sniffs, external air is sucked in known quantity through orifice plates and mixed in with odourless air, obtained by

passing ambient air through the active carbon filters. The operator sniffs the air at a high dilution and slowly increases the size of the orifice until the perception threshold of the sample is reached. The value on the pre-calibrated corresponding orifice represents the concentration of the smell of the air, expressed in number of dilutions compared to the threshold, D/T (Dilutions to Threshold).

However, numerous studies performed by odour experts concluded that the values obtained by the device were not at all comparable to those obtained by an odour laboratory. The inaccuracy arose from two main issues: the rate at which the evaluator sniffed had a large impact on the dilution accuracy, and the

Environmental Science & Engineering Magazine

January 2013 D5_ES&E 13-01-31 9:44 PM Page 51

Odour Measurement fact that the supposedly odourless air used to dilute the sample was not always odourless. The activated carbon filters were not always sufficient to clean the ambient air to be used as the zero air.

Due to the large measurement errors, these devices are usually not accepted by environmental agencies.

A new approach Last year, IDES Canada Inc. developed a field olfactometer from a completely new and fresh perspective. The Scentroid SM100 does not rely on filters to clean ambient air, but rather uses pure air supplied from a small, two kg tank that the operator carries on their back. This feature ensures that the diluting air is completely odourless, regardless of ambient conditions.

The evaluator wears a mask that allows them to breathe odourless air during the test and prevents breathing in the ambient air that could affect the sense of smell.

The principle of the SM100 closely resembles that of an olfactometer used in any odour laboratory. Odourless air is passed through a venturi device that creates a vacuum to draw in sample air. The

www.esemag.com

ratio of the odourless air to the sample air is controlled by the evaluator using Scentroid’s flow regulator valve, which has 15 set positions that correspond to specific dilution. The unit can be configured in the field to have different dilution ranges to gain further accuracy. The diluted sample

Scentroid SM100 features an extremely wide measurement range for a portable device, starting at 2 odour units (OU), corresponding to a barely detectable odour, to 30,000 OU, for an extremely strong odour not usually found in ambient air.

The Scentroid SM100 does not rely on filters to clean ambient air, but rather uses pure air supplied from a small, two kg tank that the operator carries on their back. is presented to the evaluator through the Teflon nose mask.

The operation of the Scentroid SM100 is fairly simple and straightforward: 1. Wear the Teflon mask and portable compressed air tank.

2. Open the air valve to purge nose with three minutes of odourless air.

3. Slowly open the flow control valve to increase the concentration.

4. Stop when the odour becomes detectable.

5. Read from the valve position indicator to get the sample strength.

The instrument features a dedicated sample bag connection that allows it to measure not only ambient air, but also samples stored in a Tedlar bag. This feature is extremely useful in measuring odour concentrations emitted from biosolids, liquid surfaces or smokestacks, using flux chambers or other sampling methods. Furthermore, the SM100 can also be used to assess the sensitivity of the evaluators using n-butanol reference gas in accordance with the industry standard EN13725. continued overleaf...

than 30%. Results showed that minimal training requirements and capacity to conduct n-butanol screening allows anyone to act as an evaluator.

The second case study performed by

The ease of use and high accuracy of the SM100 opens new perspectives for those who manage potentially odorous systems.

An extensive study was performed by Dr. Knut Wiik, of the odour laboratory Purenviro in Norway, to assess the accuracy, repeatability and ease of use of the SM100.

The first case study was performed at a fishmeal factory. Three local candidates, with no previous olfactometry experience, were chosen and given 10 minutes of training on the use of the SM100. Panelists were screened using n-butanol to have a fairly similar sensitivity. They were then instructed to measure the odour intensity of the same sample bag consecutively. All panelists were able to operate the machine properly and the total variance in measured odour strength was less

Dr. Wiik compared the odour strength of samples collected at a local landfill, wastewater treatment plant and fishmeal factory, using the SM100 and Purenviro’s accredited six-panel olfactometer. This study showed that the SM100 results are exceptionally accurate and compatible with those obtained by the accredited laboratory.

Another case study was performed by Anna Bokowa of Ortech in Mississauga, Ontario, to compare the SM100 and its inhouse eight-panel olfactometer on samples collected from inlets and outlets of a biofilter. This showed that in all instances the SM100 results were extremely precise and within the accuracy of the stationary

olfactometer.

The ease of use and high accuracy of the SM100 opens new perspectives for those who manage potentially odorous systems. The low cost of the system allows plant operators to save substantially on lab fees, as well as to conduct more frequent self-assessment. The supplementary data can be very beneficial when dealing with complaints that may arise from the neighbouring population.

In addition to plant operators and odour consultants, the SM100 is also being used by government field inspectors, such as those from the Ontario Ministry of Agriculture, Food and Rural Affairs, to conduct quick and cost-effective odour impact assessment.

Geotube technology protects New Jersey shoreline from Hurricane Sandy

A

t the end of October, 2012, Hurricane Sandy hit the Caribbean area and subsequently the eastern coast of the United States with devastating force.

Sandy claimed dozens of lives and caused damage amounting to $30 billion.

TenCate Geotube® containers had been placed in the dunes in parts of the coast of New Jersey, which restricted the erosion of the shoreline there.

To help with dune restoration, dune dikes with TenCate Geotube containers were constructed along the New Jersey shoreline, starting in the 1990s. In 2010, a total of 1.47 km of these containers had been installed. This afforded places such as Ocean City, Sea Isle City, Beach Haven and Atlantic City optimal protection against hurricane forces. No needless precaution, as it turned out recently. The tubular containers in the row of dunes managed to withstand the pounding waves that buffeted the coast as Sandy struck.

The tubes lived up to expectations, even though part of the dune was washed away.

In September, 2008, 5m-high waves generated by Hurricane Ike, one of the predecessors of Sandy and Isaac, which also hit in 2012, ravaged the coast of Galveston, Texas. The damage remained reasonably restricted thanks to the row of Geotube containers along the shoreline.

Ocean City’s beach after Hurricane Sandy.

Hurricane Irene hit the East coast in August 2011; containers installed at Beach Haven and Ocean City held up and protected properties.

TenCate’s long history with marine construction and shoreline protection applications started with the development of nylon bags just after the major flood disaster that hit the south-west of the Netherlands in 1953. This catastrophic event killed 1,850

Automated determination of fecal coliforms studied

By Gil Dichter

F

ecal coliform bacteria are defined as thermotolerant bacteria, which can grow at 44.5°C. The predominant strains are Escherichia coli and Klebsiella pneumoniae. Occasionally, Citrobacter freundii and Enterobacter cloacae are found.

Many microbiological methods for the quantitative detection of fecal coliform bacteria in wastewater samples are tedious and laboratory intensive. However, the Colilert-18® with its automated tray system has been demonstrated to be accurate, economical, and simple to use. In addition, confirmation of results is not required.

The Colilert-18 test is based on IDEXX Defined Substrate Technology.

As fecal coliforms grow in the reagent, they use β-galactosidase to metabolize the chromogenic nutrient indicator, ortho-nitrophenyl β-D-galactopyranoside (ONPG). The solution changes from colorless to yellow when incubated at 44.5 ± 0.2°C for 18–22 hours.

The Quanti-Tray® system is an automated most probable number (MPN) method for bacterial enumeration. When used with the Colilert-18 test, it provides automatic sample handling to produce bacterial counts in a 100-mL sample.

Procedure A snap pack of Colilert-18 reagent powder is added to a sterile vessel containing 100 mL of wastewater. The sam-

ple is mixed well to dissolve the powder and is then added to a Quanti-Tray or Quanti-Tray/2000 tray and sealed with the Quanti-Tray Sealer. The tray is placed into a water bath or incubator that can maintain a temperature of 44.5 ± 0.2°C for 18–22 hours. (Figure 1.)

ATP study The Colilert-18/Quanti-Tray method was compared with SM 9222 D to detect fecal coliforms in wastewater.

Based on the Alternate Test Protocol (ATP) study, the U.S. Environmental Protection Agency (EPA) determined that it is a suitable method for the detection of fecal coliforms in wastewater.

Primary wastewater effluent samples from 10 different locations within the

New England area were approved for use as sources of fecal coliform bacteria for this study, in order to comply with the required hold time. Effluent samples were processed and tested at an EPA-certified laboratory. When necessary, effluent samples were diluted to achieve an inoculum level of approximately 20–50 organisms per 100-mL sample. SM 9222 D m-FC plates required 20–60 colonies per plate.

Each effluent sample was analyzed by the Colilert-18/Quanti-Tray method and

by SM 9222 D in replicates of 20 per effluent site at 44.5 ± 0.2°C incubation. The sensitivity of fecal coliform detection was determined by comparing the number of presumptive positive responses for Colilert-18 with the number of presumptive

Instrumentation positive responses for SM 9222 D. Specificity was determined by confirming the identity of at least 200 presumptive positive and 200 presumptive negative samples from each test method.

Study results The mean value for Colilert-18 was higher than the mean value for SM 9222 D, possibly because SM 9222 D tended to underestimate the concentration of fecal coliforms recovered on the m-FC medium (21.5% false-negative rate). Variance homogeneity (a required parameter for the ATP) in fecal coliform recovery across all matrices for each test method was evaluated using Bartlett’s test. For the Colilert18 test, the variance across the 10 sites was similar, with a mean p-value of 0.308.

For SM 9222 D, the variance across the 10 sites was not homogeneous, with a mean p-value of 0.006.

Additional analysis using Levene’s test showed good internal consistency (p > 0.05) with Colilert-18, but not with SM 9222 D. Overall, the internal consistency was lowest with SM 9222 D, which appears to underscore the difficulty in interpreting the results of this method with true

environmental samples. Both methods had similarly low false-positive rates.

The high false-negative rate for SM 9222 D may be due to the fact that it detects fecal coliform bacteria via active lac-

These strains of anaerogenic fecal coliforms belonged primarily to the Escherichia and Klebsiella genera and represented true fecal coliform bacteria that should have been detected.

Analysts noted that SM 9222 D can be highly subjective because of varying morphological characteristics of the colonies.

Other fecal coliform colonies may lack blue color because of nontarget organisms competing for nutrients, which interferes with the growth of fecal coliforms.

The EPA determined that Colilert-18 is a suitable method for the detection of fecal coliforms in wastewater when incubated at 44.5°C. Conclusions The Colilert-18/Quanti-Tray method met the U.S. EPA acceptance criteria and was shown to be equivalent to or better than SM 9222 D for detecting and quantifying the fecal coliform population from wastewater samples. Facilities can use the Colilert-18/Quanti-Tray method to test for fecal coliforms in wastewater after obtaining regional EPA approval.

Many facilities in areas that require fecal coliform testing for wastewater have completed the process and are successfully using the Colilert-18/Quanti-Tray method for wastewater testing.

Energy Management

How to tap the energy savings in greywater

By Erwin Schwartz

M

any operators of offices, hospitals, hotels, large condos, and other buildings are aware of the need to save money and reduce their environmental impact, through better water management. The result has been the growth of ways to reduce water consumption, ranging from low-flow showerheads to landscaping that requires minimal watering.

Building operators are also aware of a similar need to reduce energy costs, and here too there has been a growth in development and installation of costmanagement measures. Saving energy has its environmental benefits as well, such as reducing greenhouse gas emissions.

However, organizations may be missing out on the opportunities that are literally flowing away from them, through the heat energy available to them through the water they dispose of.

Wastewater (or greywater) may have been heated through hot-water tanks,

3. Corporate leadership is looking more closely at energy management, partly through applying the international energy management standard ISO 50001.

Improvements in systems that help building operators recover heat from the greywater produced by their buildings, include: • A smaller physical footprint, with less need for large spaces for changing out tubes after they become fouled.

• Greater reliability, for more troublefree operation.

• Better information systems that can quantify the savings gained through greywater heat recovery.

For example, consider a relatively small hotel, with 100 rooms, that has its own laundry facility and restaurant.

Documented evidence indicates that a well-designed heat recovery system, installed for the hotel’s greywater, would save approximately $232,000 over a 15 year period. For a larger building, such as a residential condominium tower, or

Recovery of heat energy in greywater is particularly important in water-intensive industries, such as pulp and paper plants, dairies and breweries. dishwashers, laundry facilities, industrial processes, or simply from passing through a heated building. The heat in this water is a potentially valuable resource. Rather than being used, however, this heat is wasted as the water is sent into the municipal sewer system.

New developments in heat-recovery systems Several trends are forcing building operators to take a closer look at greywater heat as a resource: 1. The need to protect the organization’s financial interests from sudden energy cost increases, by using alternative sources of energy - such as heat that would otherwise be wasted.

2. The need to manage greenhouse gas emissions, through reduced use of fossil fuels - and the interests of many companies in gaining LEED certification for their buildings.

300-room hotel, the savings would likely be over $500,000 for the same timeframe. This can be done by having the building’s greywater circulated next to incoming cold water before it goes to the central boiler.

Recovery of heat energy in greywater is particularly important in water-intensive industries, such as pulp and paper plants, dairies and breweries. However, heat recovery is also important in sectors that process sludges, including municipal wastewater treatment facilities (WWTFs).

Another reason for increased use of heat recovery exchangers is due to recent energy cost increases and the introduction of pasteurization and anaerobic thermophilic digestion processes, as part of sludge digestion in municipal WWTPs. Heat exchangers can also be used to

support cooling, which would include reducing the load on air conditioning systems, and helping cool computing equipment such as servers. They can be used to recover energy (heating and cooling) from the huge amount of municipal sewage that flows below the street near the building.

Many industrial processes also produce sludges that may contain considerable heat, which represents a valuable resource that should not be wasted.

Three approaches to system design There are three main configurations for heat exchange systems: 1. Tube-in-Tube. As the name implies, this technology includes one tube inserted inside another, with the hot liquid (or sludge) in the inner tube. Heat gets transferred to the cooler incoming liquid in the outer tube. This design is not very efficient, due to the low heat transfer compared to other technologies.

Another disadvantage is that, in some jurisdictions, double-walled tubing is required for the inner tube, to reduce the danger of cross-contamination. The air space between the two walls inhibits heat transfer.

2. Spiral design. The hot liquid runs through a series of narrow spirals. This design requires small gaps of perhaps two centimetres for the tubes, limiting the amount of solids and sludges that

Energy Management can be pumped through, to avoid plugging.

3. Rectangular. This design uses rectangular channels, placed in direct contact with each other, with hot and cold channels alternating. Because there is no space between the hot and cold channels, this design maximizes the amount of heat transfer. It allows for thick double walls in the channels for the greywater market, minimizing chances that corrosion or erosion will cause leaks that could contaminate one flow with the other.

The rectangular technology provides for a very large gap against plugging, and the controlled width of the channel provides for a fast flow, which prevents baking to the surface. It also allows for easy cleaning, provided there are doors or cleaning ports at both ends of the unit that can open for inspection and maintenance.

Conclusion It is important to choose a system that can reliably manage any risk of contaminating the incoming flow with the outgoing flow. In some jurisdictions, this is particularly important if there is a

Water Treatment

Natural zeolites remove thallium from mining water

By Mark Reinsel and Scott Mason

A

lthough a relatively obscure metal, thallium is found in many mining waters and, because of its toxic nature, must be removed to low levels. A lowcost natural zeolite, clinoptilolite, has been found to effectively remove thallium from water at a closed gold mine.

Thallium is a soft metal now used in electronics, pharmaceuticals and glass manufacturing. Due to its potential toxicity, it is the primary contaminant of concern at the Kendall Mine in Montana.

Concentrations of thallium, cyanide, nitrate and other parameters in mine water are decreasing, but it is anticipated that water treatment will be required for the next 10 to 40 years. Treatment will cease once water quality standards and/or background levels are met.

Several water treatment technologies for thallium have been evaluated since 1996, including reverse osmosis, biological treatment, sulfide precipitation and other chemical treatment methods. However, none were found to perform as well as natural zeolites.

Zeolites have very effectively removed thallium from mine water in bench- and pilot-scale testing, and through operating a 100-gpm treatment system at the Kendall Mine for over 10 years. The zeolite treatment system is advantageous in that it is effective, simple to operate, and generates a nonhazardous waste product (spent zeolites). Toxicity Characteristic Leaching Procedure (TCLP) testing indicates that thallium is effectively sequestered on the zeolites, with less than 1% of the toxic metal being mobile.

This system, using a zeolite called chabazite (cab-a-zite), was very effective.

However, a review of previous benchscale testing, current operational results and discussions with zeolite providers, suggested that higher loading capacities might be achievable with different zeolite materials.

To evaluate performance of a lowercost natural zeolite, clinoptilolite, several sets of bench tests were run using clinoptilolite of different size gradations and 58 | January 2013

from different suppliers. Bench test results were promising and led Kendall personnel to operate two pilot tests on-site.

Pilot Test #1 A new material, 14x40 mesh clinoptilolite from Steelhead Specialty Minerals, was used in Zeolite Pilot Test #1. The previously-used zeolites are a larger material, 8x20 mesh chabazite from St. Cloud Minerals. The pilot test system used five “mini-columns” in series with gravity flow, which was modeled after the existing full-scale system, which uses columns formerly filled with activated carbon for gold recovery. Each mini-column contained approximately 230 L (180 kg) of clinoptilolite.

The maximum flow rate, without overflowing the columns, was found to be 3.9 m3/hr. After results showed that thallium removal improved at lower flow rates, flow was reduced to about 1 m3/hr for the remainder of the test.

The human health standard for thallium, which is the effluent limit for the

treatment system, is 0.002 mg/L. Influent concentration of mine water in this test was about 0.6 mg/L. “Breakthrough” was defined as the time when the thallium effluent concentration first exceeded detection limits. The pilot test was operated for 65 days, when consistent breakthrough was seen from Column 5 at the laboratory detection limit of 0.0002 mg/L. A total of 1,840 m3 were treated through the system. At the end of the test, Column 4 effluent was near the discharge limit of 0.002 mg/L but Column 5 effluent still comfortably met the limit. Other conclusions from Test #1 were that: • Clinoptilolite in Column 1 achieved a thallium loading of 0.38%. Loading in downstream columns was progressively lower.

• Spent clinoptilolite was tested by TCLP and the adsorbed thallium was found to be essentially non-leachable, as less than 1% of the thallium was liberated.

• Water quality parameters other than thallium (pH, arsenic, selenium, sulfate, etc.)

Water Treatment were not affected by zeolite treatment.

Pilot Test #2 Pilot Test #2, using another finegrained low-cost material, 16x50 mesh clinoptilolite from St. Cloud Minerals, was operated immediately afterward for 120 days. A total of 3,290 m3 were treated prior to breakthrough from Column 5.

Results showed that: • The average influent thallium concentration of 0.38 mg/L was somewhat lower than Pilot Test #, but is still within anticipated future mixed mine water quality.

• Clinoptilolite in Column 1 achieved a thallium loading of 0.32%.

• Spent clinoptilolite was again found to be essentially non-leachable.

Column 1 material was completely “spent” at the end of the test. As at the end of Test #1, Column 4 effluent was at the discharge limit, while Column 5 effluent was comfortably below it.

Treatment costs Based on these results, estimated operating costs for full-scale treatment using St. Cloud clinoptilolite (Test #2) are shown in Figure 1. Costs are based on a 0.32% thallium loading rate in the first

column and a price of $0.24/lb for zeolites. This is based on the quoted price for clinoptilolite ($0.14/lb) plus estimated shipping costs ($0.10/lb).

Anticipated thallium concentrations range from 0.30 to 0.46 mg/L. At the loading rate seen in Pilot Test #2 and a St. Cloud clinoptilolite cost of $0.24/lb, anticipated treatment costs are quite low (about $7,500/yr. for the base case at average flow and average concentration).

• Effluent quality monitoring to ensure proper operation and thallium removal prior to groundwater discharge. • Placement of water treatment residuals (spent zeolites and suspended solids) in a high-capacity lined pond.

Inflow rate to the storage ponds will vary seasonally. Total average annual flow

is expected to be approximately 16 m3/hr.

The typical treatment flow rate will be 18 m3/hr, which will partially fluidize zeolites in the columns, but still provide adequate contact time. If inflow rates do not provide enough water to meet minimum treatment system flows, treatment will be temporarily suspended until water is available.

Initial influent water quality will be similar to the range of concentrations predicted by the mixing model. Influent concentrations will decrease over time due to improving mine water quality.

Pilot testing and previous full-scale operations have shown that zeolites will adsorb more thallium when exposed to higher concentrations, as is typical with adsorbents. To maximize thallium loading, zeolite in each column will be transferred backward (upstream) periodically, with fresh material being loaded into Column 5 (the effluent or downstream end of the system), and material from Column 1 (the beginning or influent end of the system) being discarded.

It is anticipated that zeolite will be transferred by slurrying it with treated water, and pumping it from one column to another. Influent concentrations may be managed by adjusting source flows to increase removal efficiency.

Water Treatment

Measuring pH in Canadian water treatment plants can be challenging By G.A. (Redir) Obaji

M

easuring pH in a water treatment plant seems like a very simple process.

However, this measurement can be daunting due to the characteristics of the raw water and the type of treatment used in various plants.

Four of the main problems for pH measurement in Canadian water treatment plants are: • Low conductivity of some raw water sources.

• Conductivity of reverse osmosis permeate.

• Low temperature of the water source.

• Potential settling of floc and other solid particles on the face of the pH sensor.

Many raw water source intakes in Canada come from lakes and rivers that do not contain a high level of dissolved salts. These salts (sodium, calcium and potassium salts) are the main contributors to higher conductivity of water. Also, if a plant uses a reverse osmosis process, most of the salts are removed by the membranes, leaving permeate with a conductivity of under 40 μS. Why is low conductivity a problem?

A pH sensor is an electrochemical device that, when placed in an aqueous liquid, produces a voltage proportional to the concentration of hydrogen ions in the solution. The sensor acts like a battery with two half cells: a glass electrode and a ref-

erence electrode.

The glass electrode outputs a voltage that varies with the hydrogen ion concentration, while the reference electrode produces a voltage that must not be affected by the measured solution.

The reference electrode consists of a silver/silver chloride (Ag/AgCl) wire in contact with a saturated solution of potassium chloride (KCl). In order to complete the electric circuit with the glass electrode, the reference allows a small amount of

Another issue for Canadian water treatment plants is that, for much of the year, the water temperature is very close to freezing.

KCl to pass through a porous membrane, called a “liquid junction,” interfacing between the two liquids. This junction is typically made of porous Teflon, ceramic or wood.

When measuring pH in low-conductivity water (below 100 μS), the low ion concentration of the water will act as a magnet for the high ion concentration (KCl ions) inside the reference electrode.

This can quickly leach out the KCl solution, rendering the probe ineffective. The lower the conductivity, the faster the leaching.

The main symptom of this problem is initially drift, necessitating frequent recalibration, and then instability as the electrical resistance of the junction increases. As this develops, the reading will start to show flow dependence, where the actual reading will change with sample flow rate.

Also, if the “liquid junction” gets plugged with solid particles, such as floc, during the treatment process, movement of the electrolyte ions will be hindered.

This will affect the voltage produced by the element in the reference electrode and cause instability and drift as the junction resistance increases.

A refillable or flowing reference electrode can be used to overcome these issues.

1. Refillable sealed reference. This type of electrode is the simplest. It requires frequent “topping up” to maintain the level of the internal filling solution.

This electrode is mainly used in the laboratory, on a few industrial electrodes and in on-line ion-selective monitors. The liquid junction can also be changed regularly.

This sensor requires constant maintenance and does not address particle buildup on the liquid junction.

Water Treatment

ABB’s “Blue Glass” option is specifically designed to measure the pH of cold water. The low-resistance membrane has a much faster pH response, by a factor of 10, because of its lower resistance.

2. Reservoir-fed reference (flowing reference). As the name suggests, a container filled with internal filling solution acts as a reservoir to bleed solution into the reference chamber. This greatly reduces the frequency of “topping up,” and because the reservoir can be placed much higher than the sample (providing a large head pressure) the flow of solution through the junction can be increased. A greater reference solution flow rate helps prevent blockage of the junction and prevents the contamination sample from entering the reference chamber.

Flowing reference probes also offer replaceable liquid junction and a separate pH electrode that can be removed for inspection and replacement at low cost.

Using flowing reference system op-

tions will cut down on the frequency and cost of pH probe calibration and also on unnecessary sensor replacements. In this system, pH electrodes should last a long time when used in clean water.

Measuring pH at low temperatures Another issue for Canadian water treatment plants is that, for much of the year, the water temperature is very close to freezing. The pH glass electrodes are normally high-impedance devices, due to the resistance of the glass membrane, which is in series with the overall electrical circuit. It is this impedance that determines the speed of response to changes in the sample pH. As the temperature of the sample decreases, resistance increases, thus increasing response time of the measurement.

General-purpose electrodes that have impedances approaching 1,000 M Ω offer a very slow response at temperatures below 10°C. In these instances, electrodes with special formulated glass membranes that exhibit low impedance (less that 100 MΩ) have the advantage of much faster response. ABB’s “Blue Glass” option is specifically designed to measure the pH of cold water. The low-resistance membrane has a much faster pH response, by a factor of 10, because of its lower resistance. But it can only be used over a pH range of 0 to 10, and up to temperatures of 60°C. G.A. (Redir) Obaji is with ABB Inc, Burlington, Ontario.

Water Separation

Dissolved air flotation helps harvest algae for biodiesel research By Jim McMahon

S

ince 2008, the San Diego Center for Algae Biotechnology (SDCAB) has been conducting research into algal applications for biofuel. This has been a joint collaboration between several departments of the University of California/San Diego (UCSD) faculty and students, the University’s Scripps Institution of Oceanography, the Scripps Research Institute, as well as nonacademic industrial corporate participants.

In 2011, the Center moved beyond its campus-oriented algae research facility in San Diego and utilized a field laboratory in the Imperial Valley of California, about 100 miles east in the Sonoran Desert. One-acre ponds were made available by Carbon Capture Corporation, which also provided some of the on-site lab necessities.

The field location, which SD-CAB used for two months, gave the Center the opportunity to considerably expand its algae growing volume from in-laboratory vats to one-acre ponds. During this twomonth effort, the ponds used by SD-CAB were the largest field laboratory of any academic institution in North America for the growing and research of algae for use as a biofuel.

ter, and in all types of water up to a salinity of about 0.5 percent (50 percent higher than seawater). It can grow in desert ponds, using high-saline water from aquifers that cannot be used in any other ways. Algae growth is not dependent on a particular season, and can proliferate wherever there are nutrients and light.

Having performed previous in-lab research, processing smaller quantities of algae, the Center was well versed in a) growing algae; b) handling drying the biomass on racks to remove 90 percent of the

water; c) extracting the oil with a screw press, then purifying it in a centrifuge; and d) converting the oil to biodiesel using a traditional open-processing reaction method.

The algae would be tested first for levels of free fatty acids and moisture content to determine what mixture of chemistry was needed, balancing the methanol and sodium hydroxide to effect the desired reaction. However, the Center had little experience with harvesting algae from one-acre ponds.

Water Separation “We knew, starting off, that the biggest challenge would be the harvesting,� says Kristian Gustavson, part of the UCSD student-led, algae-based biodiesel research study. “We could grow the algae all day long, and once we had the dry biomass we could turn it into fuel, but it was the matter of harvesting. We experimented with several methods that were not very successful.�

After careful review, the Center selected World Water Works’ Algae Harvesting Technology Optimized (AHTO) dissolved air flotation system (DAF), which provided a highly efficient and compact treatment method.

AHTO is specifically tailored to algae harvesting. Pond water is pumped into the DAF where suspended solids in the form of algae are separated from the water by a process of dissolving air into the water under pressure, with the addition of a polyacrylamide flocculent. Upon release of that pressure, micro-bubbles form.

These micro-bubbles interact with the algae particles, attaching to the biomass surface and affecting the particle density, causing them to float to the surface of the DAF. They are then skimmed with a chain and flight mechanism to a sieved Thickening Beach™, which allows free water to be drained and thickens the algae particles, achieving an efficient liquids and biomass separation.

Patented NikuniÂŽ air dissolving technology is used to create the robust whitewater in the AHTO system, which saturates the effluent pond water entering the DAF with atmospheric air.

Up to 9,000 gallons of algae-laden water can be processed per minute, at a 95 percent capture rate, yielding up to 20 percent algae concentrations.

Heavy sand and grit particles settle to the bottom, where a timer function controls removal. The clean water is continuously removed from the DAF and piped back into the ponds, allowing new pond water laden with algae to enter for separation.

The AHTO process is a highly efficient system for separating algae from liquids. It can achieve biomass removal efficiencies exceeding traditional DAF performance. Up to 9,000 gallons of algae-laden water can be processed per minute, at a 95 percent capture rate, yielding up to 20 percent algae concentrations.

Algae - biofuel of the future When processed properly, biodiesel runs cleaner and more efficiently than petroleum-based diesel, and provides needed lubricity to petroleum-based diesel. Use of biodiesel in a conventional diesel engine re-

sults in a substantial reduction of unburned hydrocarbons, carbon monoxide and carbon dioxide emissions, as well as particulate matter, according to U.S. Department of Energy statistics.

Compared to crops used to produce vegetable oil for biofuels, algae is far more productive, being able to generate up to 50 times the yield of oil per acre.

The San Diego Center for Algae Biotechnology scientists plan to make sustainable algae-based fuel production a reality within five to 10 years. Its goal is to create a facility that provides a national and global model for the commercialization of algae fuel.

Precautionary principles needed to protect groundwater from fracking By Dr. Molly Whitworth

F

ollowing years of complaints and evidence that the controversial practice known as hydrologic fracturing or fracking was negatively affecting groundwater sources, the U.S. Environmental Protection Agency (EPA) is now supplying water to stricken families in Dimrock, Pennsylvania.

The EPA is also conducting tests to see if the hydrologic fracturing energy extraction process may make drinking water unsafe. These actions were the result of numerous complaints and a string of lawsuits. But the question remains: “Why does it often take legal action before environmental regulators act?”

The wait-and-see approach to regulation arises from a desire for conclusive information to support controversial regulatory decisions. Since the United States is a democracy and there is an army of lobbyists representing utility companies, the oil and gas industry, and chambers of commerce, all these competing interests frequently prevent quick action.

EPA regulations, like the actions of other federal agencies, are heavily influenced by the political appointees of each presidential administration. There are many interests that EPA must consider before issuing regulations. Unfortunately, the environment represents only one of these interests.

The evolution of precaution vs reaction Students of biology and sociology are familiar with the “flight or fight” responses of humans and animals, the product of our evolutionary heritage and brought on by the hormone adrenalin. In her provocative study of societal collapse, Rebecca Costa concludes that our genetic makeup predisposes us to react to present danger (e.g., rising sea levels) and that we are not hard-wired to respond to longrange threats (e.g., climate change).

Sociobiologists, most notably E.O. Wilson, who Time magazine called one of the most important figures of the last century, recognizes the limitations of our inherited abilities to deal with the complex problems of today. In an interview with Rebecca Costa, author of The Watchman’s www.esemag.com

Rattle, he notes that “the real problem of humanity is the following: We have paleolithic emotions; medieval institutions; and god-like technology.”

The politics of protection Politicians do not act easily on predicted risks, and environmental problems often fall into this category. The costs of fixing today’s problems are what voters and opponents focus on, so it is easier and politically wiser to put off fixing a future problem.

That is one major reason why we see disasters like the 2010 Deepwater Horizon Gulf oil spill or post-Hurricane Katrina flooding in New Orleans. In the latter event, funding safer levies was put off because the danger was not imminent and the costs were high.

Politicians typically do not get credit for preventing environmental degradation.

Anticipating and paying to prevent catastrophes that rarely occur do not garner

much support because of the costs of prevention.

Applying the Precautionary Principle A proactive approach is to anticipate and mitigate environmental issues before they become more dangerous and more costly to mitigate. This approach, commonly known as the Precautionary Principle, consists of the following five key elements (condensed): 1. Anticipatory action. There is a duty to take anticipatory action to prevent harm.

2. Right to know. Anyone proposing a product, service, operation or plan is responsible for providing information to the public on potential human health and environmental impacts.

3. Alternatives assessment. There is an obligation to examine alternatives to the proposed action that might result in less environmental harm. continued overleaf...

Guest Comment 4. Full cost accounting. There is a duty to consider all foreseeable costs associated with a decision.

5. Participatory decision process. All decisions must be transparent, participatory and informed by the best science and other relevant information.

Let’s explore how the Precautionary Principle is applied in practice. As an example, the U.S. has long applied the principle to estimating chemical risks. Results

for decision-making at the federal level.

However, smaller municipalities are beginning to apply it when making local decisions. Mendocino County, California’s Environmental Commons and the Mendocino Partnership for the Precautionary Principle are implementing this approach to their long-term environmental health and ecological policies and programs.

Superfund sites are cleaned up with an established standard to ensure that only one person in a million has a chance of harm — even at the cost of billions of dollars.

As a nation, the U.S. has not progressed far in applying the entire Precautionary Principle as a guiding framework

cision-making today. For example, the EPA has the responsibility under the Clean Air Act to post the Toxic Release Inventory (TRI) on a schedule to inform the public of the load of toxic substances emitted by an industry. Laws such as the Environmental Justice (EJ) provisions require rigorous public notice of any action affecting the environment surrounding low-income and poorly represented communities and neighborhoods.

TRI are potentially powerful tools to strengthen public influence in regulatory decision-making.

As for the EPA’s future action on fracking, Administrator Lisa P. Jackson has made hydrologic fracturing a priority cross-office agency issue and is addressing it at the top levels. At this point the policy is not precautionary, but it is to be hoped that there is still time to spark meaningful action.

In an ideal society, preventative measures take precedence over cost considerations. For now, it is better to be an informed citizen and to be aware of your surroundings and the environmental consequences of actions taking place around you. Then make sure your opinion is heard!

Instrumentation

When and how should you clean, calibrate or check your pH sensors? By Fred Kohlmann

A

ll pH readings are supposed to be taken and accepted only when the pH sensor is clean. After all, a contaminated pH sensor may yield an incorrect reading. So one must make sure the sensor is clean before doing a calibration.

Once a pH sensor is installed and operating, how do you determine when it is time to take it out of the process and do a cleaning, or a calibration? Does one perform both a cleaning and a calibration, just a cleaning, or just a calibration?

This is something that can be quite confusing, especially when the operational practices and procedures documented by your company’s Quality Control or Environmental Practices department may not be specific enough or too specific when they describe the procedure or the timing of when to conduct the pH calibration and maintenance.

In practical terms, users must develop their own maintenance and calibration schedule. This is accomplished by taking the pH sensor out of the process after a set amount of time to perform a visual inspection. If you do not find debris or fouling on the electrode and reference surfaces with the naked eye, rinse the sensor off in distilled water and perform a buffer check.

To perform a buffer check, place the sensor into the calibration buffers typically used and note the readings. If the readings are within the tolerances defined by operational procedures, it is not necessary to perform a calibration. For example, let us use ±0.2 pH as the tolerances for pass/fail of a pH sensor reading in a calibration buffer. If the sensor reads within this value, in the offset (7 pH) and span buffers, (4 pH), the sensor needs no further action and can be reinstalled. A calibration is not necessary.

Repeat this exercise every few days until you see a change in either the level of debris/foulant on the electrode and reference surfaces, or more than the ±0.2 pH deviation.

To a certain extent, the above procedure sets the benchmark for time be98 | January 2013

tween cleaning and calibration. Now, one needs to determine whether the sensor needs just a cleaning or a cleaning and re-calibration. This is done easily by first making sure the sensor is clean. It may be as easy as rinsing the sensor in water or as complicated as using acid or caustic solutions to remove the particular contaminate buildup. Should the above steps not yield results that are within your pass/fail criteria, it is time for a sensor cleaning.

For the pH sensor to maintain an accurate reading of the process pH, it must remain clean. Specifically, the glass measuring electrode cannot become coated and the reference electrode assembly must not become coated, plugged or otherwise contaminated by the process solution.

The following cleaning procedure should be followed: 1. Keep sensor as reasonably clean as possible.

2. Remove the bulk of contaminant by carefully blotting/wiping away debris.

Be careful not to rub too vigorously as this may cause static charge.

3. Rinse the sensor in warm tap water or distilled water.

4. Prepare a cleaning solution containing a soap and water mixture. Use dishwashing detergent and warm water.

Use only soaps that do not contain abra-

sives or lanolin.

5. Soak the sensor in this solution for up to five minutes and then gently or while soaking, use a soft bristle brush to gently scrub the bulb and reference area of the sensor.

6. Rinse the pH sensor in warm tap water and check/standardize the sensor in buffer solutions.

If the readings in buffers are still out of tolerance: 1. Soak the sensor in 5% to 10% HCI acid solution for a few – less than five – minutes. Do not use this procedure if the sensor has been used in a solution containing cyanide as this may produce poisonous cyanide gas.

2. Rinse the sensor in warm tap water and then place the sensor into a mild soap solution for a minute or two to neutralize any remaining acid and let the sensor come to equilibrium.

Rinse in warm tap water and check/standardize the sensor in buffer solutions.

If the above procedures yield results that are within your operational tolerances, the pH sensor is once again ready for use.

West Elgin operator jailed for drinking water violations The Municipality of West Elgin and three of its water distribution system operators were fined $154,500 for drinking water violations including providing false information and failing to report adverse test results. Additionally one of the operators was sentenced to 30 days in jail and received a Court Order as a result of charges by the Ministry’s Investigation and Enforcement Branch.

Lloyd Jarvis was the lead operator for the system. Chad Yokom and Michael Kalita were certified operators. Ministry staff conducted an inspection and found that the minimum level of chlorine had not been maintained in the system, log books had been altered, and false information had been provided to the Ministry.

In addition, the operators did not report occurrences to the Ministry or the Medical Officer of Health when chlorine levels in the distribution system were below the minimum level.

The Municipality of West Elgin, Lloyd Jarvis, Michael Kalita and Chad Yokom were fined a total of $154,500, plus victim fine surcharges of $38,625.

The municipality was given 30 days and the operators 180 days to pay their fines.

Mr. Jarvis was sentenced to 30 days in jail and ordered to surrender his certificate to operate a drinking water system and not to work at or operate any business or employment concerning or related to drinking water.

Biotechnology may help with hydraulic fracturing wastewater treatment Biotechnology may help with hydraulic fracturing wastewater treatment Fracking, the use of hydraulic pressure to release natural gas and oil from shale, carries possible environmental and public health risks, most notably water contamination.

A University of Minnesota research team is addressing this challenge by developing innovative biotechnology to purify fracking wastewater. The team is using naturally-occurring bacteria embedded in porous silica materials to biodegrade contaminants in fracking wastewater, a technology they originally

developed to remove agricultural pesticides from soil and water. They now have the ability to customize the technology to degrade chemicals in water used for fracking. Their goal is to make the water suitable for re-use in fracking of other wells and significantly reduce the amount of water used by industry.

The team will work with Tundra Companies of White Bear Lake, Minnesota, on silica encapsulation technologies, and Luca Technologies of Boulder, Colorado, on a related effort, using encapsulated microbes to recover natural gas from depleted coal beds.

Fracking relies on forcing millions of gallons of water, sand and chemicals deep into the earth, creating fissures that allow natural gas or oil to escape and be recovered. Wastewater returns to the surface where it is treated and released into surface water, injected back into the earth, or recycled for use for fracking of other wells.

Evaporation and filtration, the current treatment methods, are expensive. Moreover, they don’t eliminate chemicals, they simply reduce them to a concentrated form. Industrial scale evaporation and filtration are energy intensive, and both methods leave behind a chemical residue that presents a disposal challenge. www.nsf.gov
