Cover Story - All industries use heat and power but environmentai regs are posing new demands. A five-year project to create a computer program caiied ACES (Anaiysis of Clean Energy Systems) is supported by a 1.5 miilion pound grant from the UK Department of Trade and Industry. Here an engineer is using a laser to measure combustion characteristics in a 0.5 MW furnace. ACES will combine the benefits of established process inte

gration techniques with new practical methods for combustion and fouling modelling to provide more environmental benefits than existing models.

Regulations

By Andy Matwichuk and Hershel Guttman*

Ontario Proclaims Mandatory Certification of Water and Wastewater Operators

Ontarioenacted Regulation 435/93

July 26, 1993, under the Ontario Water Resources Act, creating a mandatory licensing system for operators of drinking water and domestic sewage facilities. In most areas the licens ing program will follow the guidelines for the voluntary certification program estab lished in 1986. The Regulation requires all drinking water and domestic sewage treat ment plants, water distribution and wastewater collection facilities, that are owned or operated by the Crown, or a mu nicipality, or a privately owned system, to be classified in accordance with the Regu lation.

The Regulation will not apply to a small water facility which has an average design flow of less than 100 cubic metres per day, is operated less than eleven (11) months a year, does not treat water except for disin-

fection, and in the opinion of the Ontario Ministry of the Environment and Energy (MGEE) is an excellent raw water source.

Owner Responsibilities The Owners of applicable facilities must file an application with the MOEE Director before February 1, 1994. Those facilities that were classified under the voluntary pro gram and are listed in the MOEE document titled "Water and Wastewater Facility Clas sifications" dated April 30, 1993, are con sidered valid classifications. But facilities

that were classified and do not appear on this list must submit the appropriate review schedules, which were mailed to the utili ties but were never submitted to the Certi fication Office.

By February 1, 1994,owners of applica ble facilities must ensure that all operators. Including operators-in-training have applied for a license. The issued license will be

valid for three (3) years. By July 1, 1994, owners must also ensure that the overall

operation of a facility is placed with an op erator (operator-in-charge) who is certified to the level of the facility classification. Related Requirements Facility owners must now ensure that

each operator attends at least 40 hours of continuing environmental training each cal endar year. The owner must keep accurate and appropriate records of all training ses sions.

Also related to operator certification, is the requirement for owners to provide ready access to comprehensive operations and maintenance (O&M) manuals. These manuals must contain plans, drawings and process descriptions for safe and efficient operation of the facility, and they must be reviewed and updated at least once every two years.

Owners must also ensure that logs are provided for chronological record keeping and are completed in accordance with the Regulation.

Operator Responsibilities All operators holding valid certificates issued under the voluntary program will be considered licensed under the mandatory program. All operators who were "grandfathered" under the Regulation 435 must pass the certification examination, at the level of "grandfathering", before the li cense expires.

The British Antarctic Survey (BAS) team, which first discovered a hole in the world's

protective ozone layer in the late 1970s, has now found that two thirds of the ozone shield

in Antarctica has been destroyed. This year's Antarctic ozone hole is the deepest ever. The ozone minimum is usu ally reached in the first half of October but this year a record low had already been es tablished by the end of September and even now may not have reached the limit of its depletion. The Antarctic ozone hole is an annual

phenomenum which has occurred in every southern hemisphere spring since the late 1970s. It is caused by the chemical action of chlorine and bromine released from man-

made chlorofluorocarbons (CFCs) and halons. Thanks to the International Montreal

Protocol, the annual production of these sub stances is now less than before, but the to

tal amount in the atmosphere continues to rise, dashing hopes of an early recovery for the ozone layer. The CFCs are not expected to reach their maximum concentration in the

atmosphere until around the turn of the cen tury, so the Antarctic ozone hole may con tinue to worsen until then.

Approvals streamlined for municipal projects The planning process for municipal projects such as road widening and some expansions of sewage treatment systems has been streamlined and improved. The improve ments come in the form of amendments to two Class Environmental Assessments

(Class EAs) for Municipal Road Projects and for Municipal Water and Wastewater Projects in Ontario. Class EAs are used for projects that are similar in nature and scale and that gener ally have predictable and minor impacts on the environment. If a project meets these requirements, an individual EA will not be required. The revised Class EAs were developed by the Municipal Engineers Association

thorities of Ontario). Benefits and protection John Bull of the MEA, welcomed the

amended Class EAs. "The changes will ben efit all municipalities. They will find the new process much clearer and easier to use," said Mr. Bull, who chaired the MEA/Min-

istry of Environment and Energy Monitor ing Committee. "But the bottom line is that the new Class EAs will protect the environ ment more effectively than their predeces sors."

Industry Update published by the Canada Communication Group, Flooding, the seventh in the series of Canada Water Books, is the first com prehensive portrayal of how Canadians have responded to flooding. Flooding chronicles how Canadians have

been affected by floods over the past 200 years. Feature stories throughout the book provide accounts of major floods or high light aspects of floodplain management. They cover; Hurricane Hazel flooding in 1954; the 1975 spring flood in Waterton Lakes National Park; a springtime disaster at Perth-Andover, New Brunswick, in 1987,

a flash flood in Rapid City, South Dakota, U.S.A., from which valuable lessons in

floodplain management were learned. Included is a detailed description of what Canadians have done to prevent and pre pare for floods through the identification of flood risk areas under the national Flood

Damage Reduction Program,the creation of flood forecasting centres, and by promoting public awareness of floodplains. Copies of Flooding - Canada Water Book are available for $29.95 in bookstores

or from the Canada Communication Group - Publishing, Ottawa, Canada KIA 0S9.

For highly contaminated loamy soils other more complex processes are nec essary. ENTSORGA 1994, the Interna tional Fair for Waste Disposal and Recy cling,from May 18 to 21 at Cologne's exhi bition centre, will present a wide range of machines and processes for the decontami nation of polluted soils. In simple terms the various pollutants can be treated as follows:

•sandy,oil-contaminated soil at gas stations, oil-refineries and due to oil-leakage can be treated at a soil washing plant. • kerosene-contaminated soil from airports or military sites is best treated by biologi cal means from an ecological point of view. • materials which can neither be washed

In environmental reporting, companies describe the impact their operations have on the environment, as well as any progress they have made in this area. The KPMG survey revealed that, despite growing regu latory and stakeholder pressures for disclo sures of environmentally related informa tion, environmental reporting is still in its infancy. However, the survey shows that Cana

These include consulting; R&D; water, air and soils analysis and remediation; technology transfer and the treatment of organic residues. Since 1990, this group has directed more than 300 projects and sales have risen from $254,985

in 1988 to $6 million for the year ending April, 1993. For these achievements, Le Groupe Serrener Inc. has been awarded win ner status in the 1993 Canada Awards for

Business Excellence Environment category. The group's four divisions each have their own specialty. The consultants of Serrener Consultation Inc. analyze environ mental projects and propose innovative so lutions in accordance with regional and regulatory needs; they also advise business leaders who wish to set up infrastructures to ensure the safe disposal, treatment and 8f

recycling of dangerous wastes. C.R.E.A. Lab Inc. directs the research and laboratory analysis for several municipalities and in dustries. Valoraction Inc. specializes in the dewatering of sludges from various sources, and a wide range of composting, as well as the treatment of waste waters. Alinag Bro kers Inc. acts as an intermediary for the pur chase and sales of industrial byproducts, notably industrial and agricultural residues. Over the last five years, Le Groupe Serrener has invested 10 percent of sales on average in R&D and conducts the larg est R&D environmental program in Que bec thanks to its association with four Que bec universities and supplementary funds from the public and private sectors. Since its creation in 1987, the business has grown rapidly, largely because of its application of cost-effective advanced tech nologies. The DAB Swedish sludge dewatering system, Hydrostop impermeable liners, the Mediaflex biological filter, Turborator lagoon aerators and Sittler windrow turners represent 40 percent of Le Groupe Serrener's sales in 1992.

element Is discovered In Ontario lab By Tom Davey

Itwasjust before Christmas and the ana

lytical laboratory was in darkness, save

for a lone work station at the far end of

the room. Despite the long recession, the glass skyscrapers still gleamed bril liantly on the Toronto skyline, colorful icons falsely proclaiming a long departed prosper ity. In the laboratory, the murmur of high tech machinery occasionally broke the si lence as Tina,a small slim woman,intently scanned the peaks of a print-out. A gradu ate chemist, she was affectionally called Tiny by some colleagues, not because of her stature, but for her enthusiasm in seeking infinitesimally small particles in .samples. To her, analytical chemistry was an art, as well as a science and she often stayed late in the lab, seeking what she termed, the tiny perfect particle. Some lab technicians fondly called her the femiogram fatale. Now Tina shook her head as she con centrated on the reams of data. Then she

spoke softly into an inter-office phone. Moments later the lab's two principals strode in.

Tina handed over the print-outs along with her notes. "I've never seen anything like this," she said. "What I have discov

The others waited respectfully, waiting for the revelation, as the crochety elder scientist paused for effect. His voice rose as he began to explain.

Marley appeared stunned. After more than two decades as a government scien tist, he had only vaguely been aware of the possibility that the dreaded black ink even existed; now he was confronted with its ter rifying reality.

Marley broke the silence, having scanned the print-out. "In all my years with the government I never saw anything even remotely like this. Perhaps it's a deviant carbon," he suggested, puzzled.'"Whatever it is, there hasn't been a trace of dark mat ter like this since the NDP came to power."

Aspres ures of our economy and

Bill Balfour, P.Eng., M.B.A.,

Canadian manufacturers are Ini

tiating new and innovative projects to re main competitive. Frequently, these projects require consultation and even formal ap proval from the Ministry of the Environment and Energy (MOEE)in order to proceed. It is amazing to see the range of issues that an industrial proponent must address when planning to build a new facility or to change an existing process. Presently, a Certificate of Approval(C of A)is required for the following types of projects: a) projects involving the disposal, handling, processing, or storage of waste materials; b)recycling projects at sites that do not meet the strict requirements set out in the new Ontario 3Rs Regulations (published as an unofficial copy in April 1993); c) projects to alter an existing process that is regulated by a C of A, including approv als for air emissions;

d) waste water treatment projects that will discharge to a waterway or sewer system.

While environmental approvals can and, in some cases, should be coordinated in-

house by the manufacturer, input from a third-party expert related to the viability and environmental impacts of a proposed project can often expedite the approval process. While many industrial companies are ex perts within their particular business niche they don't have, need, or necessarily want an in-house environmental or waste man

agement department. Although interesting and challenging, the coordination of environmental approv als for industrial clients is often somewhat

unusual and a little different than the typi cal services provided by traditional consult ing firms. This article describes some of the issues encountered during the approval process for Atlantic Packaging Products Ltd.

and Champion Photochdmistry Limited,two manufacturers assisted by an environmen tal consultant to introduce innovative recy cling technologies. The role played by a consultant on many environmental approval projects is unique and changes based on the needs of the cli ent. In Champion's case, the consultant and the proponent's staff worked closely to gether, with staff from each company han dling specific responsibilities based on ar eas of expertise. In Atlantic's case, the consultant was retained to coordinate and act as a spokes man for the company on most technical matters.

process whereby a photographic or x-ray image is developed as a negative or printed into a recognizable form. Disposal of used chemicals, classified as liquid industrial wastes, has historically been a problem for most photofinishers. Regulators have found that sewer discharges from photofinishing operations frequently exceed the local sewer use by-law limits for silver, iron, bromide, phosphorus, chlorides, sulphates, nitrogen, biological oxygen demand, and some organics.

Given the problems faced by their cus tomers, Champion introduced NatureCare, a new product line and a new approach to distributing photochemicals. It provides the following benefits: a)delivery of products in a ready-to-use for mat;

b) pick-up of used chemicals; c)elimination of sewer discharges and nonreusable packaging materials (bottles are washed and reused); and d) treatment of used chemicals to reuse, re cycle, and reduce residual wastes. To implement this system, they required two separate approvals, one to transport waste materials and a second to operate a facility to process the waste chemicals. To maintain their competitive advantage and

mated 275,000 tonnes of recycled newsprint and magazine stock annually, the facility also generated a by-product, known as pa per fibre sludge. The consultant assisted Atlantic Pack

aging in expediting approval for a program to utilize the paper fibre sludge as an or

ganic soil conditioner. The C of A required that a qualified consultant be retained to assist in the environmental management of the program. The consultant's role was in creased to encompass the following: a) project management; b) review and inspection of all farm sites proposed to receive paper sludge; c) technical communication and presenta tions on Atlantic's behalf with the public, farmers, and municipal councils; d) environmental testing of paper sludge, ground water, and soil; and e) design and implementation of field trials to assess the benefit of the landspreading program.

Prior to retaining an environmental con sultant, Atlantic worked for almost two years to have their application approved. Upon retaining a consultant, Atlantic received approval within two months. The ability of a manufacturing company to manage such a massive and environmentally sensitive project appeared to be a major considera tion in the MOEE's review of the project. The sludge spreading program is now entering its third year. The team consisted of Atlantic, advised and supported by an environmental consultant, and serviced by a licensed contractor. To date, in excess of 16,000 acres (6,500 ha) of farmland have

Atlantic Packaging Products Ltd. In 1991, Atlantic Packaging opened a new, state-of-the-art newspaper recycling facility in Whitby, Ontario. The two new mills and associated de-inking processes were capable of producing newsprint and tissue paper from 100 percent recycled feed stock. The mills were the first of their kind

in Canada and quickly became an integral part of provincial recycling initiatives. The mills also presented Atlantic Packaging with a serious and unforeseen waste management problem. In addition to utilizing an esti

program's success the management system has been successful and has become rou

tine to the point that Atlantic now manages it internally. Both of the recycling programs approved for these two manufacturers were recognized by the Recycling Council of Ontario(RCO) during their annual Waste Minimization Awards. Atlantic Packaging Products was presented the Chairman's Award for signifi cant contributions to local recycling efforts and for responsible management of a recy cling by-product. Champion Photochemis try was recognized for developing new mar kets for recycling used photochemicals. This year. Champion Photochemistry was one of six recipients of Environment

Reviving our water and wastewater infrastructure

Wafer and wastewater upgrades are stalled - but we have both the means and

the money to revive them

Infrastructure renewal conjures up pic

tures of multi-lane expressways, bridges, airports and new public build ings. An even more important infra structure is seldom given the attention it de serves because it is mainly hidden from view - our water supply and sewerage systems. To look at it another way, potholes in our highways are obvious and important exam ples of infrastructure deterioration. But they are usually small compared to a watermain break or of a sewer collapse, either of which can cause major disruptions to transporta tion as well as to the organizations and peo ple directly affected by a loss of service. The availability of clean water and the proper treatment of sewage are important to almost all economic activities and are fundamental

to public health. Ontario is among the most advanced ju risdictions in North America in the devel

opment and planning of infrastructure. Our lead is especially significant in the fields of water and wastewater. China, Central Eu

budgets solely on rate revenue without tax assistance. They can set rates to pay for re habilitation and system improvements, and establish capital impost funds so that they are able to expand their systems to accom modate growth. Utilities in Ontario, and elsewhere in Canada, have led the way toward stand alone organizations serving their popu lations with a wide range of municipal serv ices including telephone, cable, television, electricity, gas, and public transportation. The recently proclaimed Ontario Clean Water Agency (OCWA) is indeed an ex tension of this approach to public utility fi nance and is now operational. It will serve

The dilemma we face in Ontario is

largely due to the impossible tasks our mu nicipal governments are facing in keeping their books balanced while paying signifi cant sums toward other public services. The remedy is to begin to regard both water and wastewater systems as one stand-alone, selffinancing entity. We believe that our municipal water sup ply and wastewater administrations must be

OCWA's investment in systems is legis lated so as to be accounted on a cost-recov

ery basis. The debt resulting from OCWA's capital expenditure will not be considered as part of the Province's debt, but will be guaranteed by the Province. Another very important change that should be encouraged by OCWA is to help municipalities combine responsibility for their water supply systems with their sewer systems. If this can be accomplished, the combined utility can set rates that will fur ther the goals of conservation and rehabili tation.

In Ontario alone, the water supply and sewerage infrastructure has an estimated total asset value of $50 billion â&#x20AC;&#x201D; $35 bil

Provincial Lifeline programs were of fered to municipalities to assist them in cor recting the state of these hidden, but essen tial, "hard" services, and to develop pro grams to rectify the problems identified. However, this assistance falls well short of the target. If one considers a $35 billion in-ground asset and a hypothetical 100-year life (a best-case scenario) then, in the simplest terms, about $350 million should be spent each year to look after existing water and sewerage systems.

Water industry experts are recommend ing annual rehabilitation programs in the order of two percent of the current replace ment value. At present, we are not even close. Less than $100 million is being spent annually on rebuilding our infrastructure. The above-ground assets are also in need of rehabilitation.

Treatment plant optimization studies are being encouraged to identify where deficien cies exist. As an example, if we look at sew

age treatment facilities, 24 percent of On tario's plants failed to meet their certificatesof-approval or Ministry ofEnvironment and Energy (MOEE) policy effluent guidelines in 1990. This is not surprising considering that the total average daily flow of all plants has now reached 85 percent of the hydrau lic design capacities of these facilities.

Servicing growth requires more capital If we look at the Greater Toronto Area,

where the highest rate of growth in Canada is expected to occur, we find that an addi tional two million people are expected to be living here by the year 2011.But,in 1991, more than 92 percent of the water, and 80 percent of the wastewater treatment plant design capacities were already being used. The fact that many treatment facilities are reaching their design capacities while growth is projected at a significant rate means that water and wastewater infrastruc

ture will have to be upgraded and expanded. Based on MOEE infrastructure needs in

the next 15 years, the following capital works programs have been identified: $ Million

Can we afford it?

We believe there is an important first step. We must identify the full costs of our water and wastewater services. All Ontario

municipalities should be required to iden tify these costs according to universal ac counting principles that recognize full cost recovery â&#x20AC;&#x201D; including costs associated with systems and plant maintenance, and replace ment.

Anyone familiar with the planning and management of water and wastewater sys tems may find this first step obvious. How ever, the public and elected officials must be informed. We discovered a lack of un

derstanding when we made presentations to government related to Bill 17, setting up the Ontario Clean Water Agency. In developed countries, such as Canada, one to two percent of the total household income is generally considered to be afford able for water and sewage services. In 1991, StatsCan indicated that the average family income in Ontario is $58,634. This level of income suggests that a household expendi ture in the range of$580 to $ 1,160 is within reason for water and sewage. In 1991, a program to up-grade infra structure was proposed by the Ontario Re gional Municipalities. It recommended a gradual increase in water and sewage rates to about $800 per household. It is interest ing to note that in many areas of the United States and Europe expenditures are already

at this level.

Five steps to stability There are five steps that must be taken to put our water and wastewater systems in sound financial and operational order. 1. Implement water conservation to ensure water is supplied effectively. 2;. Make full cost pricing a requirement for all Ontario Municipalities. 3. Raise user rates to support full cost pric ing. 4. Reserve the revenues generated solely for capital and operating costs of water systems. 5. Provide special funding for smaller mu nicipalities that are unable to catch up on their own.

Operations

Flow monitoring — at no extra cost?

An unexpected bonus was found

in the SCADA (Supervisory Con trol and Data Acquisition) sys tem recently installed by the City of Burnaby for its Public Works central alarm system — the ability to monitor in flow and infiltration (PI). PI is an environmental problem becom ing increasingly important to arrest. Burnaby,B.C. is just east of Vancouver,and the Greater Vancouver Regional District is already well into the process of coordinat ing local activity in the Region to tackle this problem. Bumaby's new flow monitoring capability has made it a leader in local I/I abatement programs. The new SCADA system was intended, initially at least, to provide only a central alarm system for its water, sanitary, and stormwater pumping stations. But the sys tem's industrial controller — called the

Unitec AT-RTU(Advanced Technology Re mote Terminal Unit) — features a real time

calendar clock for time-and-date stamping events. A small program was written into the alarm system configuration, so the timeand-date stamping of a pump's on and off cycles can now be used to calculate flow volumes over time. This has made flow

monitoring simple and inexpensive. The AT-RTU is fully integrated to pro vide a full range of SCADA operating ca pabilities, so Burnaby's flow monitoring needs were fully met by what is now a stand ard feature of Unitec's system. The built-in clock in the AT-RTU allows

the flow monitoring feature to be used in a polling-based or on-line real-time system. When time-and-date stamped, information about events, alarms, and other activities is

transmitted to a master station when polled. The polling period may be seconds, min utes, or hours apart. But the AT-RTU re tains the information until requested by the master terminal unit (MTU). The informa tion received by the MTU is converted to flows by the system's Man Machine Inter face(MMI)software, FactoryLink. The system configuration and specifica tion was prepared by consulting engineers Kerr Wood Leidal Associates and their

electrical sub-consultants,Emeo Engineer ing. Kerr Wood Leidal project engineer,Ted

Burnaby Public Works Engineer Dana Soong at master terminal unit computer demonstrates monitoring capabilities of Unitec SCADA system. Steele, says,"The combination of flexibil ity inherent in the MMI software with the broad capabilities of the Unitec equipment allow this type of remote data logging to be very effective." Dana Soong is Water and Sewer Engi

neer for Burnaby Public Works."Being able to calculate continuously in real time the

flows coming out of and into our pumping stations is very valuable for our sanitary analysis," he says."Now we are able to iden tify areas of higher inflow and infiltration and take appropriate measures for abate ment."

As for its central alarm setup, the origi nal reason for Burnaby's installing the Unitec SCADA system, the City has been able to save significantly in day-to-day op erating costs as well. Bill Carey is Chief Dispatcher for Bumaby Public Works. He has 16 years of broad-based experience working for the City and estimates their new alarm system alone could be saving them, on average, about $2,000 a month through the reduced dou ble-time and travel costs of nuisance calls.

"Before installing this system, we had to send someone out to investigate every single alarm, because we didn't know what

it was until we got there," Carey explains.

"Now, because the central computer identi fies the type of problem that's being alarmed, we can determine if the problem is a false alarm, perhaps due to an identi fied problem at the site that's already being taken care of," Carey explains. "Or, we can tell if an alarmed event at night is a real emergency or if it's just a stuck float switch that can wait until morning when crew time is less expensive." The system, already in place, has the po tential for huge future expansion with mini mal extra capital costs (such as additional remote units and wiring). "We're confident enough in the system now that we're definitely going to expand it during the next several years," Soong says. "We're planning to add all our water PRV (Pressure Reducing Valve)stations onto the system over the next five years. And if we do decide at some point down the road to use the system for control of plant functions, then we won't have to purchase any addi tional major equipment."

Design innovation = cost savings Unitec president John Smyth says his company's AT-RTU is the result of a tech nological design innovation, claiming his

unit has 200 times more processing power and speed than a standard RTU, yet it's no bigger than a PLC (Programmable Logic Controller). Smyth claims too that the AT-RTU in

cludes — as standard built-ins — many fea tures that normally have to be purchased as additional accessories for PLCs or RTUs.

Bumaby had previously estimated, for example, that a separate flow monitoring system alone could cost it up to $27,000 per station for magmeters, dataloggers, commu nications system, and programming. The fully-integrated Unitec AT-RTUs, however, cost under $5,000 per station. For more information,

Subsurface contamination

Assessments and solutions for

soil gas infiltration problems petroleum hydrocarbons, or volatile organic compounds (VOCs), the amount, type, and time when it was released will determine if

such a contaminant can cause a problem. Subsurface Soil Gas Pressure

Soil gases move in the subsurface and into buildings either by advection (move ment due to pressure) or molecular diffu sion. Although both mechanisms can influ ence indoor concentrations of pollutants, it has been shown that gas movement by advection is typically the major transport mechanism into buildings where soil gas problems are experienced. Soil gas pres sure differentials between the inside of the

Fig. 1: Soil gas infiltration

In the context of investigating subsur

face contamination problems,environ mental professionals are frequently called upon to assess the quality of in door air for safety and health concerns. Many such problems may emerge from the migration of landfill gas, or the nearby spill age of petroleum hydrocarbons, and other miscellaneous volatile organic compounds

(VOCs). A recent survey of houses affected by soil gas infiltration, commissioned by Canada

Mortgage and Housing Corporation (CMHC), showed that a common protocol used for making such an assessment in volved taking a few isolated indoor meas urements, and then interpreting the results. Readings are normally obtained with the use of portable meters, or more infrequently with sorption tubes and personal sampling pumps. The practice of taking a few iso lated readings does not provide sufficient data for an accurate assessment of the prob lem. For professionals working in the en vironmental field, this is particularly rel evant from a liability perspective. This arti cle outlines:

The need for well developed approaches to indoor air sampling, and Typical solutions used if soil gas infil tration problems are identified. Much ofthe current understanding ofsoil gas entry mechanisms into buildings has 24

been derived through research aimed at pol lutants such as radon, methane, and water

vapour. One of the most important lessons learned through the study of these gases is that indoor air pollutant concentrations re sulting from soil gas influx can be extremely variable in time and space. Longer term monitoring of soil gas influx problems has shown that the level of soil gas pollutants indoors may change orders of magnitude over several hours. As can be appreciated, if only a few isolated indoor air samples are randomly taken over time, the conclusions derived from the analytical data may not be complete. Resulting interpretations may be: inconclusive, which could result in further

unwarranted testing; erroneously low, result ing in possible dangers; or erroneously high, resulting in excessive remedial efforts. In order to make accurate assessments

of indoor air problems resulting from soil gas influx,an understanding of the basic fac tors influencing this variability must be evaluated. The variability of indoor con centrations of soil gas pollutants is related to the five following principle factors: Gas Production

The greater and more consistent the pro duction of soil gases, the more likely these gases will become a problem. Methane pro duction, for example, is dependant on the nature of the waste, age, and degree of mois ture content. For other pollutants, such as

buildings and the soil are affected by: baro metric pressure changes, wind,stack effects, and mechanical ventilation or heating sys tems. Surface sealing such as wet or frozen soils, paved parking areas, or tight clay material can effectively trap gases causing subsurface pressures to increase. Availability and Extent of Travel Pathways Permeable subsurface geologic forma tions from source areas to the building en velope as well as entry pathways into the building are necessary for effective soil gas transport. Various (unsaturated) geologic formations such as sand,gravel (often found in utility corridors), fractured till, or rock facilitate gas movement. Common entry pathways into basements include: cracks, construction joints, exposed earth surfaces, untreated concrete slabs, or weeping tile systems.

Air Exchange Rate Air exchange with the outside air can vary from house to house depending on tem perature differences, vapour tightness of the building, mechanical air exchange systems, etc. Air exchange rates are often lower in compartmentalized basements, a condition conducive to the buildup of gases. If suffi cient air exchange occurs, indoor concen trations may be significantly lower. Other Sources

The identification of soil gases indoors may be complicated by the presence of other indoor and outdoor sources. Contaminants

that are present indoors may be a result of outdoor contamination, building material emissions, or the activities of occupants. In order to evaluate soil gas sources, a good understanding of the indoor airflow regime and sorption effects is necessary. Soil gas infiltration assessments are car ried out for two purposes: safety or health concerns. Safety concerns are normally re lated to short-term events, typically when concentrations reach explosive levels. Health concerns are related to both short-

inferences could be drawn, documentation of indoor concentrations and the factors in

fluencing the variability would be required.When long-term exposure is being assessed, sampling should be conducted over a long enough period to reasonably re flect temporal fluctuations. Long-term ex posure would need to consider source strength, exposure times, average air ex change rates, and mixing factors. For many problems, it is not practical or financially possible to fully assess the vari ability of soil-gas pollutants indoors or the factors that influence this variability. Nev ertheless, the practice of measuring/ analyzing only a few isolated indoor air sam ples will not provide sufficient data for making credible conclusions.

medium for water, says the au thor, presents a viable alternative to chlorine. The Europeans have been using ozonation technology to treat their water for many years. The technology came to North America in the early 1970s and, by 1977, 24 water treatment plants in the U.S. had installed ozone systems and 15 more were under construction or design. Today,according to one AWWA report,there are approximately 40 facilities in the United States and 40 to 50 in Canada which use an

ozonation process for water treatment. The trend is towards the use of treatment

and disinfection techniques that minimize the use of chlorine in order to limit the for

mation

of trihalomethanes (THM).

Ozonation has been shown to be the most

viable alternative to chlorine in the design of new facilities.

In recent years owners and operating en gineers of many existing water treatment fa cilities are planning to modify their facili ties not only in terms of disinfection tech nology, but also to improve the control of taste, odour, and colour and remove

trihalomethane precursors. Ozonation ret rofit of older plants is a practical alterna tive to consider.

Delcan recently undertook to upgrade the water treatment plant for the Town of

Dunviiie in Newfoundland. And this project demonstrates how ozonation technology can be applied to a medium sized plant of 1400

mVday capacity. Dunviiie lies just west of St. John's and draws its water from a natural impoundment known as Wyse's Pond. Water quality var ies throughout the year, depending on the amount of snow melt or rainfall. Typically, spring raw water quality is high in turbidity and suspended solids, whereas fall water quality is high in colour caused by organic material. The raw water is typically soft, highly aggressive with a strong, musty taste and colour. The existing water treatment facility included a raw water screen, chemi cal dosing pumps for pH adjustment and a gas chlorine injection system. The Town actually contacted Delcan as far back as the early 1980s, when it decided to improve drinking water quality. We con ducted treatability studies to assess means of colour removal, improvements to taste and odour,turbidity reduction, iron removal and corrosion control. We also conducted

treatability screen tests using pH adjustment in conjunction with such treatment alter natives as:

The preliminary tests served to identify a suitable treatment process; the ozone dos age rate is highly dependant on the specific raw water quality variables such as pH value, turbidity, alkalinity, colour, taste and odour. We recommended an on-site pilot test program to determine an effective treat ment process for all the variables, to optimize the ozonation process, chemical dosages, type of filter media, mixing times, ozone contact time, etc. For example, raw

physical chemical process included: • Low sludge production, • Significantly reduced chemical costs and chemical handling, • Lower overall operation cost, • Simplicity of operation, • Produces better water quality. The major cost is the power consump tion of the ozone generator, typically at 30 kWh/pound of ozone generation. However, based on a typical dosage of6 mg/L of ozone at 1400 m^/day water consumption, the power costs at $13,000/year would be sig nificantly less than the chemical cost for a lime/soda treatment process ($120,000). Based on this, the ozonation treatment proc ess became the preferred option for the wa ter treatment facility improvement.

Evaluations were made under the follow

3. dual stage ozonation incorporating filtra tion between stages, 4. ozonation plus sodium hydroxide and lime/carbonate.

Water samples were analyzed for pH, colour, TOC,iron and odour. The results of

the pilot plant study showed that the pre ferred treatment consists of a single stage ozonation with a dosage of 6 mg/L with a minimum contact time of 5 minutes. Ozone in this case serves as a chemical

oxidant and disinfectant; a measurable re

sidual of ozone is used to control dosage. However, this residual is not sufficiently stable in the water distribution system to provide continuing bacteriostatic-activity. It is recommended that after the ozone disin

fection process, 2-5 ppm of chlorine be added.

Treatment Plant Design Detailed process, mechanical and elec trical designs were carried out in 1990. Special attention was paid to the specifica tion and selection of an appropriate ozonation system based on operator safety, existing plant constraints, and system con trol.

Past experience from Europe and from Quebec showed that an ozonation system requires specialized technology for design and manufacture. As the components are closely interrelated, the onus is on the ozone system manufacturer to develop a process package which is efficient and durable. Consequently, emphasis was placed on the development of bidding documents that in cluded performance guarantees. Operation Safety Ozone is a noxious gas, causing irrita tion to the respiratory tract. The current standard for ozone level in the workplace is 0.1 part of ozone per million parts of air (ppm) average over an 8 hour work shift. This may also be expressed as 0.2 milligram of ozone per cubic meter of air (mg/m^). The ozonation system is placed in a con fined room and isolated from the rest of the

treatment plant. The room is of air-tight design with a continuous trace ozone gas monitor, remote alarm and emergency ex haust system. In cases where ozone is de tected, the ozonation system will shut down automatically and the emergency exhaust system will be energized to evacuate the excess ozone gas. The ozonation system and alarm must then be reset manually, after the operator has diagnosed and corrected the problem. To prevent the discharge of ex cess ozone to the atmosphere, the off gases are passed through a catalytic ozone destruc tion system with a removal efficiency over

Wastewater Treatment

A New Single-Pass Aerobic Blofliter for On-Slte Wastewater Treatment

The most widely used apparatus for

on-site treatment and disposal of domestic sewage wastewater is the conventional septic system. The septic tank is an effective biological reactor that treats the wastewater anaerobically and then discharges it directly to the tile bed for

removes organic matter, ammonium, bacte ria and other undesirable contaminants. The

treated water percolates down through the unsaturated soil horizon and is discharged directly to the groundwater. Because the septic tank is independent of the environment, it provides consistent treatment regardless of soil and drainage conditions in many climates. Not so with

The majority of these deaths oc cur in people over age 70. How ever, cancer is not just a disease of the eld erly; it is the leading cause of death for women aged 20 to 44, accounting for over 1,000 deaths in Canada each year. Given these sobering facts, it is vital that the public be informed about what causes cancer. A Gallup poll conducted for the Canadian Cancer Society discovered that: "Cancer is seen as having an unknown cause; as being a powerful disease with a mysterious course of its own,controlled by fate and not by its victim nor the medical profession." The poll also found that most people believe that cancer is the leading cause of death even though cardiovascular disease is actually the number one killer in Canada.'

Instead of focusing on the lifestyle decisions which can signifi cantly reduce one's risk of getting cancer, the television networks

focused on the environmental causes of cancer which pose a rela tively small risk but are not within the control of the individual.

This attention to the causes of cancer may have been a factor in the finding that Canadians think that cancer is "a powerful dis ease with a mysterious course of its own, controlled by fate and

Photocatalytic Treatment of Wastewater Effluents

In a paper presented at the 43rd Canadian Chemical Engineering Conference, J.E. Valladares described the work of his col

leagues at the University of Western On tario on a novel photocatalytic reactor for the mineralization of organic pollutants. The reactor is based on a flow-through annular system with the light source placed in the

centre surrounded with a TiO^ photocatalyst supported on glass mesh. Using methylene blue as a model pollutant, typical results showed essentially complete photo conversion in 30 minutes. Kinetic models

were developed for extrapolation and scaleup of this photocatalytic system.

Regeneration of Granular Activated Carbon

A paper accepted for publication in Water Research describes laboratory experiments undertaken to investigate the feasibility of regenerating granular activated carbon (GAC) electrochemically. Using GAC loaded with phenol, R.M. Narbaitz and J. Cen conducted the regeneration in a batch reactor filled with 1% NaCl solution as the

electrolyte. With cathodic regeneration, which was 5 to 10% more efficient than

anodic regeneration, at a current of 100 mA for five hours, these University of Ottawa scientists achieved a regeneration efficiency of 95%. Multiple regenerations only reduce the efficiency by 2% per cycle with no ap parent carbon losses.

Figure 1: Electromagnetic spectrum with expanded scale of UV radiation.

In the past ten years a great deal ofresearch has gone into the

designing and testing of uitravioiet disinfection systems for

wastewater.(Venosa, 1983; Thampi, 1990; Stover et al., 1986; Severin and Suidan, 1985; White et al., 1986 and Palmateer and Whitby, 1987). This has resulted in ultraviolet light being accepted as the alternative to chlorination and chlorination/dechlorination for the disinfection of wastewater.

Since ultraviolet light is not a chemical agent, no toxic residuals Visible light FLUORESCENT

LAMP

What is ultraviolet light and how is it produced? The term ultraviolet(UV) light is applied to electromagnetic radiation emitted from the region of the spectrum lying beyond the visible light and before X-rays (Figure 1). The energy of a photon of light is inversely related to the wavelength; therefore UV light is very powerful compared to visible light. All UV light is invisible to the human eye. For UV disinfection, we are inter ested in the wavelengths between 200 and 300 nm (Inm = lO'm). For practical applications, UV light must be generated from low pressure mercury germicidal lamps( Figure 2). These ger micidal lamps,operate electrically on the same basic principle as fluorescent lamps. UV light is emitted as a result of an electron flow through the ionized mercury vapour between the electrodes of the lamp. The two basic differences between a UV and fluo rescent lamp are phosphor compounds which convert UV to vis ible light on the inside of the glass of the fluorescent lamp and the soft glass of the fluorescent lamp which will not transmit UV light. This soft glass and phosphor coating are replaced in the UV lamp by a highly purified form of glass called quartz which transmits ninety percent of the UV light produced by the lamp. About eighty-six percent of the UV lamp's radiant energy is at a wavelength of 254 nm and about one percent is at other germi cidal wavelengths. Of the total power input to the UV lamp and ballast approximately 25 percent is emitted as germicidal light whereas a medium pressure lamp only produces 12 percent of its radiant energy below a wavelength of 300nm. The bluish-green glow which is observed from a UV lamp is a result of light given

which absorb or reflect UV light. Figure 5 shows the effect of a soluble organic compound and suspended solids on the UV trans mission (Whitby el ai, 1985). As the percent transmission gets lower (higher absorbance) the ability of the UV light to penetrate the wastewater and reach the target organisms decreases. Figure 6 illustrates the effect of an UV absorbing soluble compound on

How UV light Inactivates microorganisms As shown in Figure 3, UV light below a wavelength of 300 nm has the ability to kill Escherichia coli. As shown in Figure 3 the ability of UV light to destroy E. coli and the absorption spec trum of its genetic material or deoxyribonucleic acid (DNA) are identical. A microorganism can no longer divide and survive if a

vital genetic function is destroyed in the DNA by the UV light. All microorganisms are destroyed by UV light. The most de structive UV light is at 260 nm which is very close to the wave length of 254 nm produced by germicidal lamps. Therefore the UV light from a low pressure mercury lamp is very efficient as a germicidal agent. Figure 4 shows the log fraction survival curve of a pure culture of E. coli B/r and faecal coliforms in wastewater when they were irradiated with a constant intensity of UV light (Whitby, 1988).

There is a characteristic curve like this for all microorganisms. Algae (Whitby, 1988) yeasts (Whitby, 1988) and Ciardia (Rice and Hoff, 1981) are much more resistant to UV light and this results in a large shoulder or flat portion at the start of the frac tion survival curve and the slope of the linear portion of the frac tion survival curve is not as steep.

the fraction survival curve shows that a constant fraction of the

The flattening out at the bottom of the curve of E. coli B/r occurs because some of the bacteria which are in clumps are pro tected from the UV light.

Obtaining the proper information about the level of suspended solids is very important for the sizing of the UV system.

or size of the UV lamps must be propor tionately increased to maintain the same dis infection requirements. Therefore the UV system must be designed for the maximum flow rate at the end of lamp life. The UV unit must be designed so that it provides as much sideways motion as pos sible with very little forward mixing. This makes sure that every microorganism is ex posed to the average dose of UV light. This is especially important when the water has a low UV transmission or high suspended solids. The open channel UV system where the wastewater flows parallel to the sub merged lamps has a very good hydraulic profile as shown in Figure 8.

appreciable effect. A laboratory study using the collimated UV beam method of Quails and Johnson (1983) will determine whether the disinfec tion requirements can be obtained with UV light. This data will also provide the dose of UV light which can be used to size the UV system.

Figure 9: Results of the output of quartz- sheathed UV lamps in flowing water as determined at various lamp ages. The height of the wastevvater above the top row of UV lamps must be rigidly controlled by a flap gate or weir at all of the flow rates. Therefore the UV system must be designed for the maxi mum flow rate. This is especially important if the wastewater treatment plant receives stormwater runoff. Iron or Hardness

Iron affects UV disinfection by absorbing UV light. It does this in three ways. If the concentration of dissolved iron is high enough in the wastewater the UV light will be absorbed before it can kill any microorganisms. Iron will precipitate out on the quartz sleeves and absorb the UV light before it enters the wastewater. The third mechanism which is just being investigated is the ad

sorption of iron onto suspended solids, clumps of bacteria and other organic compounds. This adsorbed iron will prevent UV light from piercing the suspended solids eic. and killing the en trapped microbes. The UV industry has adopted a level of 0.3 ppm as the maximum allowable level of iron but there is no data to substantiate this limit. The level of iron should be measured

in the wastewater and if it approaches 0.3 ppm a pilot study should be instituted to determine whether the disinfection level can be

attained and what the cleaning frequency should be. An in-place cleaning system can be incorporated in the UV design. If possi ble a wastewater treatment plant should be designed with a noniron method of precipitating phosphate. Hardness affects UV disinfection because calcium and mag nesium salts crystallize out on the quartz sleeve which surrounds the UV lamp and this prevents the UV light from entering the wastewater. A pilot study will determine the frequency of clean ing if the wastewater is very hard so that an in-place or other cleaning system can be incorporated into the UV equipment. Wastewater Source It should be determined whether the wastewater treatment

plant receives periodic influxes of industrial wastewater which may contain UV absorbing organic compounds, iron or hardness which may affect UV performance. These sources may be re quired to pre-treat their wastewater. Disinfection Requirements The disinfection requirements will determine the size of the UV system and whether UV light can attain the level of disinfec tion that is required. 46

UV lamps will last much longer if the UV system is designed for the proper end of lamp life. The results of this study are shown in Figure 9. Therefore a UV system could be designed for an end of lamp life of three years. The UV lamps should only be replaced when the microbiological results become unacceptable and no other factors such as quartz sleeve fouling can be found to be causing poor disinfection. Extending lamp life dramatically reduces the operation and maintenance cost of a UV unit. Equipment Design Table 2 shows the features which should be incorporated into a UV system for wastewater.

The most important development in UV design for wastewater was the modular open channel system with the flow of water parallel to the submerged UV lamps. An example of this system is shown in Figure 10. Until this development, pressurized UV systems for drinking water were used. These systems suffered from large pressure drops due to the accumulation of debris on the UV lamps because the water flows perpendicular to the lamps. The entire system must be shut down to change a lamp or other component and this necessitated having one hundred percent back up. When the water flows parallel to the UV lamps debris can only catch on the front or back of the lamp rack where it can be removed by a high pressure hose. When the UV system is modu lar any component can be replaced without shutting down the entire system. The open channel modular system using weather proof components eliminates the need for pumps and buildings. A chlorine contact chamber can be turned into a UV disinfection channel.

Single open-ended quartz sleeves and UV lamps with all of the electrical connections at one end eliminate fifty percent of all the water seals and electrical connections.

Each UV lamp must be individually isolated from the rest of the system so that water cannot enter the entire UV rack if a quartz sleeve or water seal fails. The interior of the UV rack Environmental Science & Engineering, December 1993

Each UV lamp must be monitored so that an indicator lights up when the UV lamp bums out. If all of the indicator lights are always on the operator must search for the indicator light which is out. When hundreds of indicator lights are involved the lights out for normal operation is a much simpler system to monitor and the indicator lights have an unlimited lifetime. The system must have the proper ground fault detectors, fuses and circuit breakers for safe operation. An hour meter will give the operator an indication of when to replace the UV lamps. A UV sensor system consisting of an UV probe in each array of UV lamps and an alarm and/or meter will alert the operator to

All of the microbial indicators showed that UV light was more effective than chlorine at disinfecting wastewater. Bacteriophages or viruses to E. coli were measured as a surrogate for human viruses to determine whether UV light or chlorine was more effi

cient at killing viruses. UV light killed significantly more vi ruses than chlorine. Therefore UV light may be destroying more human viruses. SUMMARY

fouling of the quartz sleeves, aging of the UV lamps and changes in the UV transmission of the wastewater. The UV meter must

only measure light at a wavelength of 254nm. Sensors using filters to eliminate visible light may be degraded by moisture and the high intensity of UV light. The operator can correlate the readings of the UV meter with the indicator organisms and deter mine when the quartz sleeves must be cleaned or the UV lamps must be replaced. A low water level alarm can be used to turn off UV lights if

UV light is a viable alternative to the chemical disinfectants for destroying pathogenic microorganisms in wastewater without producing any toxic by-products. Practical experience has shown that an open channel modular UV system with submerged lamps which are parallel to the flow of water is the system of choice for ease of operation and maintenance.

the flow of water falls below a critical level.

A device to control the level of the water over the top row of lamps is very important because the water must be maintained between 1.3 and 2.5cm to insure proper disinfection. A flap gate or a weir can be used for this purpose.

Efficacy of UV Disinfection Table 3 (Palmateer and Whitby, 1987) shows the results of disinfecting two parallel streams of a secondarily treated wastewater with UV light and chlorine. A free chlorine residual of 0.5 mg/L was measured at the end of a 30 minute contact time.

An open channel parallel flow UV system with two banks of UV lights was used for the experiments.

tices for oily water treatment. These practices, although not necessar

ily mandated by regulators and legislators, have been widely accepted over the ensu ing years, mostly by the petroleum industry from the standpoint of environmental re sponsibility and liability concerns. Recently, regulators at all levels, have been considering and adopting more specific codes and criteria governing oily water ef fluent quality. These codes are covered gen erally by the Ministries or Departments of the Environment under various Environmen

tal Protection Acts and/or Water Resources Acts. The unofficial consensus for the maxi mum allowable concentration of "free oils

and grease" is 15 milligrams per litre (mg/ 1) or 15 parts per million (ppm). Accord ing to engineers in the field of hydrology, this level of oil could be visualized by the familiar "blue" sheen on the water surface.

The science of oily water treatment has evolved a great deal since the early days. Theory The earliest method for separating oils from water used settling ponds and lagoons. Allowed to remain in a quiescent state for an adequate amount of time, all components that were in separate phases (ie not dis-

The next development towards improv ing separator performance was the advent of a series of flat or corrugated plates ori ented parallel to one another, which permit ted flow between them in the long axis of the separator chamber. Some designs ori ented the plates in an incline to improve col lection and migration of contaminants (up for oils and down for solids).

The spacing of the plates ranges typi cally from 100 millimetres to 18 millime tres depending on the design. The plates, fabricated from steel, serve several pur poses:

Many distinguished engineers and scientists offered to serve on our advisory board when we launched Environ mental Science & Engineering six years ago. We are pleased to announce three more appointees, Jim Bishop, Pierre Beaumler and Don Kemp. All are ES&E contribu tors.

I first met Jim Bishop when we both served on an MOE advisory committee on drinking water. He was tireless in providing information on water resources, pollution impacts and remedial actions to correct water problems, terrestrial and sediment contamination as well as various MISA Im

plications for industry. He left the MOE to become Vice President of Environment Protection Laboratories some

four years ago. Jim was born in BC and received his B.Sc. in Analytical Chemistry from the University of Alberta. Dr. Pierre Michel Beaumler is Vice President of

Loyola College in 1969 with an honours degree in chemis try, later gaining his doctorate from the University of Wind sor. He is currently President of the Association of the Chemical Profession of Ontario and is most energetic in

trying to gain licencing status for chemists in Ontario. Some recent ES&E editorials on licencing stem directly from Pierre's ACPO initiatives.

Don Kemp, P.Eng., is a Director of MacViro Consult ants. He received his B.A. Sc. (Civil Engineering) and M.A. Sc. (Environmental Engineering) both from the Uni versity of Toronto. He has worked in both Industrial and municipal wastewater projects, as well as environmental planning. Don has been active in professional associa tions, such as the seminar committee for the Water Envi ronment Association of Ontario, formerly the PCAO, and the Executive Committee of the Environmental Engineer ing Division of the Canadian Society for Civii Engineering.

• substantially reduce the distance that a particle must rise to be collected. •increase the relative amount of surface area

available for collection (visualize a pond surface area stacked into a series of flat

plates.)

• provide a medium onto which small di ameter oil particles can agglomerate or coa lesce into relatively larger particles and droplets. Consistent with the Stokes' Law princi ple, these larger particles are more suscep tible to flotation at a higher rising velocity. Consequently higher efficiency oil/water separation occurs than with an API design. This type of technology has traditionally

To assist, the Director has formed an Advisory Committee made-up of Industry Stakeholders,such as operators and professional organizations. Concerns and questions can therefore be directed not only to the MOFF, but to these representatives. Earl Baldock who chaired the Advisory Board of Certification, has agreed to chair this committee.

ments:

• The cross sectional shape of the M-Pak combines corrugated plates (to Increase sur face area) that are inclined so as to guide the contaminants up or down the plate stack. These plate stacks are assembled in paral lel arrays. • Distance between adjacent plates has been reduced to 6.5 millimetres, resulting in a reduced rising distance. This plate spacing has been designed to optimize separation, without adversely affecting flow resistance. • The plate material Is molded from corro sion resistant polypropylene. Polypropylene is an "oleophilic" or oil attractive material. Small oil particles will temporarily adhere to the underside of the next vertically adja cent plate and in collision with other oil particles,"coalesce" into larger particles and droplets.

If you have CFCequipment, you have a problem. Venting CFCs and the law. Venting CFCs into the atmosphere is now illegal in many jurisdictions. •Replacing a commercial chiller can cost over a hundred thousand dollars.

•Converting it to HCFCs can cost up to a hundred thousand dollars.

•Adding on a high efficiency CFC capture unit can cost in the tens of thousands.

Halozone equals compliance. It's a technology, a system and a full ser vice team that lets you use CFC chillers to the end of their effective lives while com

plying with CFC emission legislation.

Comply without converting. Blue Bottle™ Service from Halozone is the

least expensive option to bring your CFC chiller into compliance. Once the Blue Bottle Cylinder is full of captured CFCs your Blue Bottle Service team replaces it, and takes it back to Halozone's plant to reclaim and recycle the CFCs.

• Is the influent flow intermittent or con tinuous?

• Will the separator require additional oil holding capacity? Coalescing separators are designed and available in general size ranges based on flow and effluent quality requirements. However,the design of these separators can be optimized to suit specific applications by using a special software program that con siders separator influent parameters and effluent requirements.

Product Review Diaphragm Seal

Toxic gas monitors

Red Valve's Series 742 Diaphragm Seal isolates and reads gauges, transmitters, and pressure switches, making it ideal for use in chemical or slurry service. The series can be installed perpendicular to the pipe line so that, in the event of plugging, the elastomer slurry ring area which isolates the instrument can be flushed or rodded clean.

As process pressure is sensed by the 360degree elastomer sleeve, the captive fluid transfers the process pressure to the instru ment, providing a consistent, accurate read ing. Features include mounting in any flow direction and threaded ends manufactured
