Literature Review

Cover Story Greater public awareness of pollution and its iii-effects, coupled with increas ing legislation — including European Community Water Directives — have brought a need for industry, agriculture and water authorities to find some answers.

The problem of environmentallyharmful liquid waste is being tackled by scientists at the University of Kent in Canterbury, south-east England, whose work revolves around the use of ver

satile, natural, microbes (bacteria). La boratory-based biochemical and micro biological research is being put to the test in a pilot plant at a water treatment works. Here, researchers are gathering samples at a lake close by.

roorganisms in soil and water biodegrade many waste products and this process — together with chemical and photochemical breakdown, as well as the effects of dilution — reduces many potential pollutants to below detectable levels. However, the capacity of the na tural environment to eliminate pollu tion is far from absolute because of the

volume and diversity of organics in volved and their continued release.

Two triazine herbicides, atrazine and

simazine,have recentlyjoined the list of chemicals causing concern and the En vironmental Microbiology group at Kent's Biological Laboratory, com missioned by Britain's Foundation for Water Research, is investigating the use of naturally-occurring bacteria to de grade these.

Editorial Comment

Why are hot dog vendors and hairdressers licenced while chemists aren't?

In 1902. George G. Nasmith began serving as chemist and bacteriologist to the Ontario Board of Health. His quali fications were remarkable. He held an M.A.. Ph.D.. D.P.H. and D.Sc.. all from

While this analytical progress rivals space age technology,too many govern ment agencies commission laboratory services as if they were buying sand and

tario. Being a learned profession, the chemists wished to be licenced like ar

chitects. lawyers or doctors. Not for the first time the chemists were turned

down,probably on the advice ofgovern ment bureaucrats.

The government Is more concerned about protecting us from poor haircuts or bad hot dogs — than it is about protecting both the pubiic and the environment from unqualified chemists.

These days chemists routinely detect toxins in the parts per trillion ranges: indeed a few labs can find contaminants

History has shown many times that laboratory findings can be misread.The famous Birmingham Six in Britain were only recently acquitted after it was pro ved that prosecution"s forensic data were poorly interpreted. Chemicals in playing cards had been identified wrongly as being from explosives. The six men had been convicted following an IRA bombing incident. After serving long prison terms, they were acquitted after lengthy appeals.

Analytical chemistry is increasingly at the forefront of environmental regu lations. In rejecting the chemists" de mands for licencing, the public"s posi tion is now clear. The government is more concerned about protecting us from poor haircuts or bad hot dogs — than it is about protecting both the public and the environment from un qualified chemists.

Industry Update Lake Huron water

supply system saves

$200,000 on electricity charges The Ontario Ministry of the Environ ment (MOE) operates a Water Treat ment Plant in Grand Bend, Ontario to

provide London and thirteen other municipalities with potable water. The plant operates 24 hours per day. seven days a week and produces water at an average rate of 15 MIGPD and a peak rate of about 65 MIGPD. Electricity ac counts for approximately fifty five per cent of the total operating costs for the plant.

To reduce the power demand and electrical operating costs of the plant.

Ontario Hydro and the MOE have been working diligently on a demand man agement program. The strategies being employed are as follows: i) review operations to determine where load could be reduced or shif

ted to off-peak hours. ii) install more energy efficient equip ment

iii) conduct detailed engineering audits to determine the cost effectiveness

and feasibility of process and/or operating modifications The review of operations yielded sig nificant results. Certain lighting and electric heating loads totalling over 100 kW were deemed unnecessary and dis

mand charges was realized, resulting in a cost savings of over $100,000 per year.

All of these operating changes required no capital or operating costs but saved the facility over $200,000 in their power bills.

toxic compound, and a multiplier was chosen,based on the toxicity ofthe com pound,to build in a "safety factor".These levels were ultimately set for the purpose of protecting both aquatic and human life over long term exposure.

There are several major drawbacks to this method of assessing industrial dis charge. Firstly, many of the limits were initially set at levels close to or below that which could actually be measured, even with today's technology, with any accuracy. In fact when using GC/MS chromatography, analytical technol ogy, which is heavily relied upon for detection of many chemicals, large peaks of nontoxic compounds can often hide smaller toxic components and con sequently only a few toxic compounds can be accurately identified.

Secondly, setting limits across the board using the results of laboratory tests, may not apply to natural systems.

Each industrial or municipal discharge has its own set of very unique chemical and physical characteristics that may alter(increasing or decreasing) the tox icity of the compound in question.

Ultimately a better way of determin ing effluent quality standards has be come recognized.That is to measure the effects of chronic exposure of aquatic systems to these effluent streams. Pre sently there are no standard methods of developing, maintaining and exposing these natural systems or mesocosms to industrial effluents. In an effort to sim

plify and more accurately reflect real world situations, while improving efflu ent quality,the use of whole effluent tox icity testing using single test species has become standard protocol.

of environmental regulators if toxicity persists.

The TIE is composed of three phases which if performed in a stepwise fa shion can identify the toxic component(s)of an effluent(Figure 1). With this information in hand, plant pro fessionals can perform site audits and initiate specific treatment programs and/or change plant procedures or pro cesses to reduce or eliminate that spe cific compound and in turn reduce overall effluent toxicity.

Phase I or toxicant characterization

tests are designed to identify the physi cal/chemical properties of the toxic components of the effluent stream

through a series of manipulations.Each manipulation is then followed by tox icity tests on standard test organisms.

The purpose of each manipulation is intended to change the physical or che mical characteristics of the sample and therefore remove or make a group of known toxicants biologically unavail able to the test organisms.

Phase I of the process only partially

An example of a Phase I test is one that has become familiar to Ontario in

The results of the TIE can be used in order to determine the most economical

method of dealing with the effluent tox icity. If the results of the TIE indicate a specific chemicalculprit it is often most efficient to eliminate or replace this chemical at source.

We Go Under

As is often the case though, in the older industrial complexes of southern Ontario, waste streams are not always fully defined or the toxicant may come from a process that is not always on line and may appear sporadically in the ef fluent. In these cases it becomes difficult to trace the toxic source or to follow its

Overseas waste management

Waste management techniques affecting the food industry

In Britain, public concern over

waste disposal matters and the in adequacy of laws to safeguard amenities, precipitated the setting up of a Royal Commission on Environ mental Pollution in 1971. It has con

tinuously investigated specific issues, publishing 12 reports to date, and has recommended changes in techniques, legislation and enforcement.

Supplementing these investigations, the European Community has passed 280 pieces of environmental legislation in the last 20 years. Many ofthese pollu tion control procedures and standards are incorporated in British legislation.

Future actions may include environ mental auditing, labelling of environ mentally friendly products, and eco nomic disincentives to complement regulatory methods of pollution

been a feature of the last two decades.

In Britain it is difficult to make an

accurate independent evaluation of gross expenditure on waste management techniques affecting the food industry.

For many years the Department of the Environment has funded research into

the technical aspects ofcontrolled waste management. In 1990 it financed the areas of work shown in the tables.

• The pricing and regulatory structure for surplus electricity, generated by combined heat and power schemes, should be made more favourable.

• Value added tax(VAT)on energy effi ciency products should be lowered to reduce the distortions caused by the

zero rating of energy. VAT is compar able to Canada's GST. • Incentive schemes should be con

sidered for implementing energy effi ciency measures.

Future Policies

Britain's target is for 25% of all house hold waste to be recycled before the year 2000. For industry to reduce waste, the requirement is to change production methods and use waste materials by up grading them, where necessary.

Major energy-consuming industries, such as food and drink, a significant proportion of whose running costs is devoted to energy,should set themselves targets for energy efficiency. They must also reduce their carbon dioxide emis sions.

Clarifiers are an integral com

The prin ciple is straight-forward: sus pended solids that are placed in a qui escent state will experience settling according to the relative specific gravity of the solids in the mixed liquor. Pri mary clarification is a simple mechani cal separation process to facilitate the reduction of the load on the secondary, or biological treatment unit. Final clari fiers accept biologically digested mixed liquor and perform final sedimentation prior to disinfection and discharge.

can handle the biological loads placed on the system. The recent emergence of intra-channel clarifiers has taken the

ditch concept one step further. By plac ing a clarification device into the oxida tion ditch channel to provide a quie scent settling zone, the need for a final

clarifier and return sludge pumping is eliminated.

The Boat Clarifierâ&#x201E;˘

One example ofan intra-channel cla rifier operating in combination with an oxidation ditch is the Boat Clarifier.

developed and marketed in the United States by United Industries and curren tly being introduced into the Canadian market place by Trenton Environmen tal Equipment.

This is a boat-shaped clarifier unit

ofthe clarifier.The shape ofthe clarifier permits floating debris in the ditch to pass along the sides of the unit, which avoids scum accumulation on the water surface. Clarified effluent flows over an

adjustable weir in the bow of the boat and passes on to disinfection.

Plant operators of the more than 100 treatment plants have praised this clari fier for its simplicity and effectiveness.

Initial capital costs are less and O&M costs significantly less than with con

ventional systems. Painting, preventa-

creases in velocity and creates the head differential required to remove the sludge from the clarifier. Influent enters at the stern of the boat. Sludge settles and is returned to the ditch through ports on the bottom of the boat. Sludge pumping is eliminated. Surface troughs within the unit collect floating material, including scum, and return it to the ditch through scum ports near the stern

Since external clarifiers and digesters are eliminated for the most part, land requirements are considerably less. Re liability is a strong feature since the majority of the treatment is hydraulic

fixed into an oxidation ditch. Waste

and thus maintenance free.

In many cases, samples can be analyzed with little or no pretreatment.

Major corporate moves at Gore & Storrie

The Board of Directors of Gore & Storrie Limited

George G. Powell, P.Eng. A civil engineering grad uate from the University of Toronto, Mr. Powell joined G&S In 1962. A vice-president of Gore & Storrie since 1980, he

was appointed President November 7, 1992.

Mr. Powell is currently a director of the Water Environment Federation

and a past president of the Pollution Control Asso ciation of Ontario. Other association work has

is pleased to announce the appointment of George G. Powell, P.Eng., as President and Chief Operat ing Officer. Robert A. Goodings will remain as Chairman and Chief Executive Officer, focusing on strategic planning.

Founded in 1919, Gore & Storrie provides environmental engineering and science services to governments, municipalities, and industry in Cana da and abroad. The company focuses on water sup ply, wastewater treatment, municipal services, water resources, and solid waste management.

The corporate moves are designed to respond to the increasingly complex demands of today's environmental problems. A more holistic approach is now required in planning capital works, which must encompass socio-economic factors, environ mental impacts, pollution prevention, water conser vation, higher levels of water treatment, and safe disposal practices. These corporate changes expand Gore & Storrie's leadership and scope of service in these pressing areas.

G&S has displayed innovative design skills in virtually every branch of environmental engineer ing. The number of honours awarded the company

included serving as com

— two of them in 1991 — is unmatched by any oth

Historical footnote 1919

The tradition continues...

1992

In 1919, Gore, Nasmith & Storrie established itself in the City of Toronto as "consulting civil engineers and public health specialists." The combination of engineering and science was highly unusual, but thanks to this distinctive specialization. Gore & Storrie is now at the forefront of today's fastest- growing industry — the en vironment.

An historical note from those early days when G&S was founded is of special interest today. In 1919, the City of Toronto's engineer was one George G. Powell. His son, John G. Powell, joined Gore & Storrie in 1932 and was made President in 1970. The tradition continues . .. but the George G. Powell that is President of Gore & Storrie today faces vastly different environmental and engineering challenges than his father or grandfather before him.

Deciding you prefer fish over 'foul' is the easy part. Resolving the environmental challenges on your menu is a lot harder. For one thing, the area of Pollution Control and Environmental Protection

today is a confusion of options, restrictions and regulations.

We urge you to attend our 22nd Annual

Conference for answers and practical approaches to a wide-range of environmental concerns. Exchange ideas with over 1600 members representing government,industry, consulting engineering, and academia - professionals in pollution control and water quality.

Presentations will cover innovative technolo

gies, practical measures,legal issues, management strategies, policy positions and more.

In addition. The Ontario Pollution Control

Equipment Association(OPCEA)will sponsor an extensive equipment exhibition.

We are the Pollution Control Association of

Ontario, a non-profit association of environmental professionals from all sectors, dedicated to the devel opment and dissemination of information about environmental technologies. We are the Ontario affiliate of the world-wide Water Environment

Federation. Our goal is to meaningfully advance the Science of Environmental Preservation.

Here's your opportunity to become a better informed participant in a concern that affects us all.

Sink or swim, we're all in this together. Don't miss it!

Clean air: It's a basic need for employee safety In your mine or plant.

Combustible and toxic gases are cause for increasing concern in the workplace. Many constitute hidden hazards not detectable by the five basic senses. However, new technologies and services from Heath now make it possible to greatly improve health and safety standards through advanced air quality control.

Heath's industrial inspection crews are fully equipped to minimize costly hazards in your mine or plant. They combine today's most advanced leak detection and gas monitoring technology with years of field experience. Heath will tailor a program to your specifications for emergency service,

scheduled inspections, independent audits or employee training. Each program is designed to do the job quickly, accurately and with minimal interference to your operations.

Heath manufactures and distributes a wide range of portable and stationary gas monitoring instruments for area air quality and safety applications. Many instruments are stock items

available for immediate

shipment. Full field servicing and calibration is provided by our instrument technicians.

Unless you screen the intake or processing water, debris in the water can choke off your pumps and processing equipment.

Modern FMC Link-Belt traveling water

screens greatly reduce the possibility of damage to valuable equipment. Their efficiency and reliability in removing floating and underwater refuse has been proven in countless installations. For the benefit of

marine ecology,FMC has developed a remote acoustic fish behavioural control device

located upstream to divert fish away from the water intake. Also available, are FMC Link-

Belt No-Well traveling water screens that eliminate the need for a concrete intake well or chamber.

NEW EXTENDED LIFE COMPONENTS AVAILABLE New FMC traveling water screen components are made of non-me tallic materials designed to with stand the harshest environments.

They provide substantial weight re duction and reduce the need for

maintenance. These newly-avail able components are completelyIn terchangeable with FMC's stand ard components, so existing traveling waterscreens can be eas ily upgraded.

tions from 0.1 to 200 ppm. No further adjustment is necessary. The meter is pre-calibrated. so that only a simple one-point calibration is required on site.

The EC63 allows users to quickly obtain accurate data in the field; thereby elimi nating sample degradation during transport and/or storage.

SUMMARY AND CONCLUSIONS

The ZenoGem™ process integrates biological treatment with state-of-theart ultrafiltration technology. The pro cess derives its technical advantages from the inherent ability of a UF to re ject suspended solids, bacteria, emul sified oils and large molecular weight soluble organics independent of the bioreactor operating conditions, wastewater quality, UF pressures or biomass settleability. Two of the key advantages are superior effluent quality(because of the absolute filtration achieved) and reduced vulnerability to upsets(because bacteria 'are not lost during upsets).

Other advantages include reduced sludge production and the fact that

Mexico City calls for bids for water distribution network modernization

The biggest trade fair for waste water and waste

disposal in the world

The newly-created Mexico City Water Commission plans to involve the private sector in a major restructuring of the city's water distribution, pricing, billing, maintenance and dis charge systems. Undertaken to alleviate the city's chronic water shortages,the modernization process will place special emphasis on improving Mexico's water treatment capabilities and creating economic incentives for using treated water in stead of pure water in industrial activities. It is expected that the new systems will eventually reduce fresh water consump tion by 20 to 40 percent and halt depletion ofthe city's aquifer.

Carlos Casasus, General Director of the Commission,says the city plans to call for bids from private sector companies shortly. Phase one of the program will entail the awarding of contracts to companies who will establish means to track down and formally register households who are pirating water.This stage will also include the installation of meters to facilitate proper billing. Phase two will seek out private com panies to manage billing systems, and Phase three will entail the wholesaling of water to private companies for distribution in different areas of the city.

The implementation ofPhase three,is expected to go a long way towards ensuring that the distribution networks are kept in good repair. Due to geologic conditions, the city's water pipes break continuously. Currently, there are no economic incentives for keeping this network up. But when private com panies have to pay for the water they are going to distribute, it will be in their interest to maintain the networks.

Mr. Casasus also noted that recent legislation mandates a new federal tax on untreated water discharged into inland waterways. Revenues from the new tax will be used to finance waste water treatment.

In explaining Mexico's water problems he said that only 76 percent of households have access to running water in their homes and only 61 percent have indoor drainage systems.

Shortcomings in the nation's water distribution system were exacerbated by the economic crisis ofthe mid-1980s. With the Mexican economy on the mend, however, improvement of water and drainage systems is a top government priority.

Problems that have plagued the country's water system include unrealistically low fixed-water rates, a large percen

tage of households whose water use is not registered or billed, reluctance on the part of industry to use treated water and a general lack of maintenance of underground water pipeline networks.

"There is currently no economic incentive for reducing water consumption," Mr. Casasus said. "The reforms, how ever, now allow us to charge for water on the basis of metered consumption.The new rates are very progressive. That is, the more water you use, the more costly the water gets. The rates are designed to make water more expensive for big users."

Mr.Casasus is extremely optimistic about the prospects for environmental protection offered by the new program."The aquifer under Mexico City is currently dangerously overexploited," he said."If we don't do something about it now,the overexploitation will deplete the aquifer in less than a decade.

But, I believe in the next decade we're going to have substan tial water consumption savings and a water treatment pro gram that will reverse that decline and return this city to a much more stable water supply. I also think it will eventually be one of the world's largest waste water treatment programs in the world."

"Removing environmental insult at its source is a profitable game. It raises productivity and quality, lowers cost, and increases shippable-product to dis posable-waste ratios. For the environ mental industry to succeed in supplying pollution prevention technologies from outside the industry in question is going to be tougher than supplying environ mental controls, and involves higher levels ofindustry-specific know-how,he told the audience.

William T, Lorenz noted that between

1990 and 1995,the Mexican government

planned to spend $2.5 billion to fight pollution. The government plans to spend at least SlOO million on its pollu tion control program in Mexico City alone through 1992. Market demand has grown due to the liberalization of

Currently the Ontario Ministry of the Environment is suggesting that the needed annual capital improvements with respect to municipal water and

Typical household bills for water only will range from $400 to $430 per annum by the end of the century.

In respect to sewerage charges, the American Association of Metropolitan Sewerage Agencies estimates that typi cal household costs for sewage service only will increase from S190 per annum to $615 by 2000 and $2,000 perannumby 2010 â&#x20AC;&#x201D; this despite the impact of con

per 1000 litres.

These higher charges based on an annual family income ofapproximately $57,000 (1990) for Ontario represent about 0.6 percent of household income and compare to a stated figure by the Ministry of Energy of 2.6 percent for energy use within the home.

The US Environmental Protection

Agency indicated that in the same ge neral period, water and sewage services were equating to $375.00 per household per year or 1.0 percent of gross U.S. an nual household income. EPA indicated

that these charges would increase to $625 per year based only on increased waste water controls. The indications
