Municipalities and Developments.

Increase capacity at lower costs while | meeting stringent effluent criteria.

ZENON membrane technology is making possible what was impossible using conventional wastewater treatment technology. In municipalities and developments around the world, Zenon is producing wastewater effluent exceeding the highest effluent quality standards - and more stringent future criteria - while dramatically reducing chemical, energy, construction and ongoing operational costs. It delivers: â&#x20AC;˘B.O.D.< 2 mg./L

â&#x20AC;˘ NH2<Q.3mg./L

TP < 0.07 mg./L TN<2mg./L

In existing treatment facilities, retrofitting with Zenon technology is dramatically increasing wastewater treatment capacity without increasing infrastructure size. Zenon mem brane technology is simplifying the purification process to meet ever increasing needs for cleaner sewage effluent, and water reuse and recycle. Zenon plants are not only renowned for their consistency

and reliability, they can operate with minimal daily site super vision while meeting the strictest regulatory requirements. Zenon membrane technology. It is preserving waterhumankind's most essential commodity -for municipalities and developments around the world.

Industry Update Ro-Flo® Rotary Vane Gas Compressors CAPP gravely concerned about Kyoto agreement

Digester Gas Recirculation & Boosting Fuel Gas Boosting for Cogeneration Landfill Gas Recovery

"The Canadian Association of Petro

leum Producers(CAPP)has grave con cerns about the Kyoto agreement," says CAPP President David Manning. "In Kyoto, the federal government committed to such an aggressive target that consumers and businesses in every province will be scrambling to find ways to cope with this deal," says Manning. "The federal government will have to fully determine and explain to all Cana dians, industry and provincial govern ments, what the costs will be before

signing and ratifying the Kyoto deal, an agreement that commits Canada to a re duction of almost 30 percent by 2012." "Let's be clear. This is not an Alberta

issue or an industry issue -this deal will affect the lives of every Canadian. The real issue is how the government will reconcile the targets agreed to at Kyoto and its commitment to no punitive taxes, more jobs and continued economic growth for Canada." Manning also expressed disappoint ment at the lack of commitment by de veloping countries.

A full complement of Ro-Flo rotary sliding vane type gas compressors is available to suit your specific digester gas handling needs. Offered in single or two-stage configurations, these compressors are uniquely designed to provide extended operating life while handling a variety of dirty, corrosive gas mixtures. For convenience, the Ro-Flo compressor can be factory equipped with a full

Industry Update Ontario playing a major role in Great Lakes cleanup Significant reductions in dioxin and furan emissions from Ontario kraft pulp and paper mills into Lake Superior are one of many indicators that progress is being made in improving water quality in the Great Lakes. Discharges have been dramatically reduced as a result of enforcement of Ontario's regulation un der the province's Municipal/Industrial Strategy for Abatement, says the MOE. "Ontario is doing its part to get rid of

persistent toxic substances in Lake Su perior and throughout the Great Lakes basin," Environment Minister Norm

Sterling said. "Ontario has an impor tant role to play in helping Canada fulfill its commitments under the Great Lakes

Binational Toxics Strategy." An example of the province's com mitment is a $9.3-million project to re move contaminated sediment from

Thunder Bay harbour, a priority site under a federal provincial agreement. The province. Environment Canada and

three companies, Abitibi-Consolidated Inc., Canadian National Railway Com pany and Northern Wood, are contrib uting to the cleanup.

Detecting water leaks by radar A radar system capable of finding un derground water leaks has been devel oped by Mecon Limited, based in Cam bridge, England. The system, which works by detecting the vibrations of a leaking supply pipe, can sense less than a micrometre of motion and is therefore

sensitive enough to record very small water losses.

The dream of a

PCB-freeToronto is becoming reality. Great news for Toronto Hydro customers! Toronto Hydro and Ego Logic have joined forces to eliminate PCB-contaminated material.

Toronto Hydro's reputation as a leader in managing PCBs dates back to the early 1980s. In fact, we've transported more PCBs than any municipal utility in Canada - accident-free. Ontario-based Eco Logic has developed an award-winning PCB-destruction process that converts PCBs into methane ^ and other reusable products. Together, we offer a complete local solution that: • Provides convenient removal of all your PCB waste.

• Eliminates the cost and potential liability of storage. • Reduces the risk and liability of long distance transportation of your waste. • The process handles any concentration of PCBs.

• Employs non-incineration destruction technology. For more information about a cost-effective alternative

to PCB storage or incineration call us at(416)591-1806.

Dr. Mark Harper, technical director of Mecon, says: "Detecting a leaking pipe is normally a time-consuming and expensive operation. Acoustic devices in use are usually laborious and slow, usually entailing the attachment of de tectors to the buried pipe, which means of course that access has first to be

gained to the pipe. "The operation is repeated until the leak is found. The radar we are develop ing will allow someone to walk along the route of a pipeline and detect leaks with out any physical contact with the pipe." The conventional use of radar is to

exploit the Doppler effect to find and track moving objects. It compares the frequency of a reflected signal to a con stant reference, thus pinpointing an ob ject and indicating its speed. "Dealing with a vibrating object is a different matter," says Dr. Harper. "Leaking pipes vibrate but the Doppler technique is not suitable for the detec tion of vibrations of this kind. It's not

sensitive enough." "What we have done is to devise a

radar which uses a wavelength of 15 centimetres and is capable of detecting the sometimes tiny vibrations of a leak ing pipe.

Treatment plant on wheels! Sani Mobile has invested $2 million in

a mobile sludge treatment unit which can reduce the volume of industrial,

pjwia

municipal and agricultural liquid sludge. Liquid sludge is injected into the clarifier of the "treatment plant on wheels", which separates the solid material from the liquid through centrifugal action. The mobile unit can rapidly reduce the volume ofsludge from wastewater treat ment, resulting in lower disposal costs. Lime can be added during the process to control the pH balance of the sludge and reduce bacteria and odours.

Industry Update Supreme Court rules in favour of Federal Government on RGBs Canada's Supreme Court has upheld the Federal Government's right to control toxic substances in Canada.

The Supreme Court ruled that using the criminal law power to prohibit toxic substances is a legitimate way of pro tecting the environment. The Court said that protection of the environment re quires action by governments at all lev els both nationally and internationally. In 1990, Hydro-Quebec was charged with an illegal release of PCB-contaminated oil under the Polychlorinated Biphenyl (PCS) Interim Order made under the Canadian Environmental Pro

tection Act(CEPA). The Interim Order

has since been replaced by regulations. As a defence against the charges, Hy dro-Quebec challenged Federaljurisdic tion to enact the Interim Order.

The Quebec Court ofAppeal and two lower courts in Quebec ruled that por tions of the Interitn Order were beyond Federal jurisdiction. The Federal Gov ernment appealed the decision to the Supreme Court of Canada, which heard legal arguments on February 10, 1997.

In giving its judgment, the Supreme Court also acknowledged that the Fed eral Government's use of the Criminal

Law to protect the environment does not prevent provinces from using their pow ers to protect the environment as well. The use of the Criminal Law power does not affect provincial authority to regu late pollution. Ontario's environmental

regulations reformed Environment Minister Norm Sterling released a comprehensive reform pack age on November 27, 1997, that could make Qntario's environmental regula tions better, stronger and clearer. The 38 reforms mark the first major revision of the province's environmental regula tions in 25 years. The reforms range from consolida tion of some regulations (such as those on acid rain)from four into one,to elimi

nating measures that actually discour age good environmental practice (such as the regulation requiring burial of empty pesticide containers rather than recycling them). The change requires they be recycled. Other regulations are being strength ened and updated; a more stringent regu

lation to reduce smog-causing vapours from gasoline is one example of tougher standards. Another new regulation sets clear and tougher rules for new boilers and other combustion devices.

"The consultation process has proven invaluable," said Sterling. "More than 125 meetings and more than 370 writ ten submissions (half of them from in

dividuals)- have resulted in a signifi cantly improved reform package." The reform process began in Novem ber 1995 with broad stakeholder consul

tations. In July 1996, the discussion pa per, Responsive Environmental Protec tion, was released, followed by further consultations. The changes will be posted on the Environmental Bill of Rights (EBR) registry for a minimum 30-day comment period.

Industry Update Public-private partnership a "Win-Win" on Saltspring Island

A new septage treatment facility at Burgoyne Bay on Saltspring Island, was provided through a Design-Build-OwnOperate tender won by Hill, Murray & Associates Inc. of Victoria, British Co

lumbia. The state-of-the-ai1 facility is designed to treat septage and sewage sludge to ground discharge quality. The plant serves all the southern GulfIslands. Hill, Murray & Associates has en tered into a five-year agreement with

Capital Regional District for provision of septage treatment services. The $250,000 facility has the capacity to han dle 300,000 gallons of septage per year. A pilot project last year demonstrated the effectiveness of the treatment proc ess. The system produces very dry cake suitable for composting. The liquid re moved from the cake is further processed through a membrane-bioreactor system which produces tertiary quality effluent. The treated water is approved by the min istry of health for ground disposal.

This sealed, continuous process renders extremely dry cakes while greatly reduc ing odours often associated with septage treatment. This proven technology is fully automated, simple to operate and maintain, and requires an extremely small footprint for operations. The septage press is a Canadian technology, manufactured by Fournier Industries Inc. of Quebec.

Research findings to be commercialized For the first time ever, the Centre de re cherche industrielle du Quebec, CRIQ (Quebec Industrial Research Centre), will commercialize a treatment process

that was perfected by the Centre. After 5 years of research, specialists at the CRIQ have developed an effective proc ess for the treatment of liquid waste from hog operations. Tests have demon strated that the new treatment, called

Simultaneous Sludge Digestion and Metal Leaching The objective of work described in Water Research was to determine

whether various sewage sludge types coming from different wastewater treatment plants could be microbially leached to solubilize toxic metals and

be simultaneously digested. Indigenous sulfur-oxidizing microorganisms from acclimated sludge were used by INRSFau scientists H. Benmoussa, R.D.

Tyagi and P.G.C. Jones to generate sulfuric acid in situ by the oxidation of added sulfur. The experiments were conducted in intemal loop tower type re actors with sulfur spheres (25 mm di ameter) placed at the bottom ofeach re actor. Batch experiments in bioreactors, using sludge from four different wastewater treatment plants, resulted in sub stantial solubilization of heavy metals during sludge digestion.

The adsorption of monophosphate ions from aqueous solutions by floes formed upon hydrolysis of alum was investi gated by J.-P. Boisvert and colleagues at the University of Sherbrooke. The phosphate adsorption processes were examined on pre-formed floes of alum and on in situ floe formation in the pres ence of phosphate ions. The results, published in Water Research, show that the phosphate-floc interactions on pre formed floes mainly involve specific interactions accompanied by or OHexchange. With in situ hydrolysis,complexation and charge neutralization ef fects play a significant part.

Elimination of Mercury by Fish Factors influencing mercury elimination by fish are poorly understood. McCill University scientists M.Trudel and J.B. Rasmussen developed a general model of mercury elimination from fish using literature data. Their analysis, published in Environmental Science and Technol

mercury and that inorganic mercury was excreted at three times the rate of

methylmercury. The model indicated that the methylmercury depuration rate was independent of mercury burden and concentration. Mercury elimination tended to be overestimated by a factor of 2-6 by empirical models that were published prior to this study.

Drinking Water

Aquifer storage recovery project at Mannheim, Ontario

During Phase 1 of the Mannheim Artificial Re

gional Municipality of Waterloo constructed a raw water pipe line from the Grand River and a water

treatment plant (MWTP) near Mann heim, Ontario. Subsequent phases of the project, which involved prototype test ing of artificial recharge, were put on hold pending completion of the Long Term Water Strategy (LTWS). The LTWS is reviewing the long-term water supply options for the Region, includ ing the use of new technology for the Mannheim project, development of new groundwater supplies, and construction of a pipeline to one of the Great Lakes. Evaluations undertaken during the LTWS confirmed the feasibility of arti ficial aquifer recharge at Mannheim,al though it was recommended that the system be re-designed to include Aqui fer Storage Recovery wells. Aquifer storage and recovery (ASR) is a more efficient water supply strategy which involves the storage of treated drinking water in a suitable underground aquifer storage zone by injection through a well when water is available.

Communal-size sewage and leachate treatment using biofiiters in process trains

The Waterloo Biofilter™ is a

new type of free-draining aerobic triciding filter devel oped in Ontario for domestic sewage but has been applied to other larger scale flows such as small munici

pass loading rates of 0.5-8 mVmVd de pending on filter bed depth, influent composition,solids content, and desired effluent quality and maintenance fre quency. The medium combines high re tention time, large open pores, concur rent aerobic and anaerobic reactions, and

high surface area for higher performance and long-term low maintenance. This article describes results from larger

In Prince Albert, Saskatchewan, a

105 mVd flow of municipal and com mercial-industrial wastewater is treated

using the Proteus® coagulation system and Waterloo Biofiiters. The facility was monitored by CETAC-West and is now operated by the City of Prince Albert. The Proteus system efficiently mixes alum with raw sewage to produce a sludge and a supernatant within a 20minute residence time.

The sludge is thickened and proc essed off-site, and the supernatant with BOD=50-100,TSS=10-40,and TP<0.5

mg/L is normally passed through graded sand filters and is then sprayed onto the biofdters in sequence(Figure 1).(BOD refers to biochemical oxygen demand over 5 days.) The sand removes solids to TSS<2 mg/L, but removes only mini mal BOD. Testing and monitoring was carried out from November 1995 to

August 1996 using one 4.5 m- biofilter,

Testing of the biofiiters without sand filters followed until mid-April 1997. The Proteus supernatant contained BOD=69-83 and TSS=21-31 mg/L and the Waterloo Biofilter polished this to

Wastewater Treatment - Cover Story

Snowfluent wins Schreyer A ward for wastewater treatment

In Canadatoday,over80%ofcom

munities have lagoons that provide either primary, or with the addition of chemicals, secondary treatment to community wastewater. Westport, Ontaiio utilized a lagoon system that dis charged into the Upper Rideau Lake twice annually. This release contained phosphorous which virtually destroyed the lake over a twenty-year period. The solution proposed by Delta Engineering was one that allowed "zero direct discharge" into the Upper Rideau

Lake. Westport is utilizing SnowfluentÂŽ as the sole wastewater treatment method.

Snowfluent combines advanced

snowmaking techniques with the natu ral freezing process of water. The proc ess of Snowfluent or Atomizing Freeze Crystallization was developed by Delta Engineering in cooperation with the Ontario Ministry of the Environment and Energy.

Composting Wastewater Sludge, cont' facility roof area, and stored within a 5,000 gallon storage tank, again to use in maintaining the proper moisture lev els of the active windrows.

Due to the range of organic materi als which are processed, and the poten tial for odours which result, an elabo

rate air collection and biofiltration sys tem was developed. This system con sists of three 225 foot-long air intake pipes, each connected to a 25hp, 8,000 cfm collection fan. The entire facility is maintained at a negative atmospheric pressure, and the system provides four internal air changes per hour. Collected air is discharged into a common header pipe which is coupled to twenty 6-inch perforated diffusion pipes. Effluent air diffuses into a 5,600 square foot biofilter bed, where it is retained for sixty sec onds to undergo odourous compound removal.

Finished compost material is screen ed through both a 2.5 and 3/8 inch mesh trommel screen. Three-eighths inch material is then bagged and marketed under the Green Country Farms prod uct name. Coarser material is presently used by various contractors as a topsoil supplement. The facility has operated at the ton nage levels predicted during the design phase. The Compostit facility design has proven to be a low capital cost al ternative when compared to other invessel systems at an overall capital cost

of approximately 1.5 million dollars (Canadian). The focus for future im

provements will be on marketing initia tives to provide consistent outlets for product sales. Compostit Inc. data provided by George South, H.B. Sc., M.A., Manager, Waste Diversion, Muskoka Container ized Services, Ltd.

Profile #2 City of Guelph Works Department, Guelph, Ontario The City of Guelph wastewater treat ment plant cuiTently serves a population

top dressing or daily cover at landfills. The City of Guelph is the first in Canada to utilize a high-rate, totally enclosed mechanical sludge composting facility. Commissioned in 1995,the facility pro duces approximately 17,000 tonnes of compost per year.

The sludge is initially stabilized by anaerobic digestion prior to dewatering on belt filter presses that squeeze the sludge between a woven mesh filter cloth and increase the solids content of

the sludge from 3% to 18%. Amend

of over 90,000 and treats about 55 mil

ment derived from waste wood is deliv

lion litres of wastewater per day, with the treated effluent from the plant being discharged to the nearby Speed River. Because of the sensitivity of this receiv ing stream, the Guelph plant employs an advanced wastewater treatment proc ess to produce a high-quality effluent. What results from this process is a sub

ered from the amendment storage silo, and is ultimately combined with dewatered sludge from the sludge storage bin and recycled compost from the cure reactor. The amendment provides a car bon-based food source that comple ments the nitrogen-rich sludge to pro vide the correct proportions of nutrients required by the compost micro-organ-

stantial side-stream of concentrated sol

ids, more commonly termed as sludge. Guelph closely examined its sludge management options and selected sludge composting as the preferred method to produce a more useful by product. Sludge composting provides an en vironmentally sound method of enhanc ing the properties of, and recycling valu able nutrients back into, soil. Compost produced from sewage sludge has the potential for landscape application, ag ricultural use, land rehabilitation, and

isms. The amendment also increases the

dryness and porosity of the mix to al low efficient movement of air through the compost mass. Recycled compost is withdrawn from the cure reactor and

contributes a population of active com post micro-organisms while also in creasing the dryness of the mix. All three components: sewage sludge, amendment, and recycled com post are discharged into screw convey ors at a controlled but variable rate prior to delivery to the mixer. The mixer

Composting Wastewater Sludge

By Donald R. Hoekstra*

Composting wastewater sludge an outline of two case histories

Thefocus ofthe water pol ution control industry has histori cally been the collection and

treatment of wastewater, and

the production of a high quality liquid stream for reintroduction into the local

environment. With improved treatment technologies and methods,the results of these efforts have been largely success ful with many plants able to consistently remove 95+% of the solids in the wastewater stream.

This increased removal efficiency has produced an increased disposal problem for many facilities, while prompting others to pursue a method of producing a value-added product from these organic residuals. Sewage sludge which has been sufficiently stabilized and subjected to a "process to signifi cantly reduce pathogens"(PSRP)can be

with a wide range of beneficial uses. One method to achieve the production of biosolids is composting. Composting holds a significant and increasingly important position in Cana da's waste management infrastructure. The Composting Council of Canada re ports(based upon information provided by provincial/territorial ministries of environment) that there are currently 252 centralized composting facilities

located across Canada and more than 30

sites that utilize in-vessel technology. Leaf and yard waste, wood by-products, IC&I (Industrial Commercial & Insti tutional) organics (including restaurant and supermarket food waste), and pa per materials are the most commonly composted materials; however, sewage sludge is being composted or co-composted in a number of these facilities. The following profiles of two suc cessfully operating facilities provide an interesting comparison of approaches to the production of biosolids compost. The first profile represents a low capi tal cost"home grown" design for the cocomposting of mixed organic waste, where sewage sludge is a main feedstock. The second represents a fully engineered "in -vessel" system designed to process only sewage sludge. Profile#! CompostitInc. Compostit Inc. was developed in *Prism Resource Management, Ltd.

wood fibre recovery and organic mate rials (including sewage sludge) may be processed at this location. Compostit, and the indoor windrow composting process it utilizes, was de veloped in an attempt to provide a low capital cost indoor composting facility, equipped with "best available technol ogy" environmental controls and suffi cient throughput capacity to serve the central Ontario marketplace. This fa cility processes 7000 to 10,000 metric tonnes of source-separated organic ma terial (inclusive of bulking agent) per year on a 4.6 acre site. The facility it self is 32,000 square feet in size with 2,000 squai-e feet committed to a public education area, a 10,000 square foot ni trogenous material tipping floor and mixing area, and a 20,000 square foot high-rate composting area. All nitrogenous materials (sewage sludge, manures, food wastes, etc) are received onto a common tip floor, where they are inspected for contaminants and overall material acceptability. Carbona ceous mateiials(including wood wastes.

S. I

wood chips, sawdust, and leaf and yard wastes) are received onto an outdoor

30.5 metre by 45.5 metre storage pad where they are stored until mixing. For processing, both nitrogen and carbon materials are placed into a twin auger paddlewheel mixer and mixed to achieve the appropriate bulk density and carbon to nitrogen ratio. Once the ma terial is mixed, it is discharged along a conveyor belt, and formed into a raw material stockpile ready for composting. Sewage Sludge Composting The raw mixed compostable material is then formed into windrows 200 feet

long by 15 feet wide by 7 feet high; it then undergoes moisture addition and aeration utilizing a Scat"elevating face" type windrow turner. The high-rate composting phase consists of 15 days at 55 degrees Celsius and five turnings. This first phase is completed in 28 days. Following the high-rate phase and at tainment of all Ontario Ministry of Environment and Energy specifications, the compost is removed from the active windrow area and placed onto an el evated curing pad where it remains for a minimum of two to three months until

cured. The curing pad is elevated to minimize the amount of runoff which

requires containment within a lined re tention pond. Water collected in the re tention pond is pumped underground into the building for recirculation onto actively composting windrows. Rain water is also collected from the main

removal (BEPR) systems have been shown to be a reli

able, effective and cost-effi

cient method for removing both nitro gen and phosphorous from wastewater. Removal is accomplished by combin ing nitrification, denitrification, and en hanced phosphorous uptake. The effect of various operating con ditions on biological phosphorous re moval processes has been studied in detail in the literature {Merseth, 1996). Furthermore,the impact ofenvironmen tal factors, i.e., temperature, pH, dis solved oxygen concentration as well as substrate availability, has been evaluated by Wentzel (1988) and Seldak (1993). Thus, the general principles for the de sign of biological phosphorous removal systems are well developed {Wentzel and Ekama, 1996). There is a definite paucity of infor mation related to the impact of inhibi tion on the performance of BEPR pro cesses, although inhibition of nitrifica tion and denitrification has been well

studied. Nitrifying organisms have been shown to be strongly inhibited by many compounds particularly heavy metals and certain organics {Gady, 1980; Topalova et al., 1995; Nowak and

Reusing sludge means cleaning it first, and Parkson has a unique prod uct for doing just that. The StrainPress SludgeCleaner removes from primary or secondary sludge etc., the nonorganic solids, e.g. plastics, pa pers, rags, that may settle or float in downstream processes. These trash solids are then compressed and ex truded as a dry product that can be disposed of with trash and screenings from other sources in the facility. The cleaned sludge can then be proc essed further to produce what the EPA has defined as "Class A sludge".

Torbo - Wet Abrasive Blasting System tor removal of coatings, painted surfaces. Including lead and asbestos. Torbo is superior to any other wet or dry blast system In use today. The Torbo method of abrasive blasting prevents the spread of air-borne lead particuiate material. Lead In the air levels is consistently below EP/VOSHAActlon Levels. Torbo provides a reduction of contaminated dust emissions of 95%. There Is a decrease In abrasive consump tion up to 50% compared to dry blast systems, and very low use of water(18 gal. per hour),thus signifi cantly reducing the cost of contaminated waste dis posal.

Composting Wastewater Sludge, cont' blends these components into a homo geneous mix prior to discharging onto the elevating conveyor. The elevating conveyor moves the mix horizontally and vertically in a "C"configuration by sandwiching the material between two continuous vulcanized rubber belts. The

elevating conveyor discharges the com post into a series ofscrew conveyors that allow the material to be deposited into the top of any of the three reactors. Five days per week, the finished

compost material is withdrawn off the bottom of the two initial reactors and

transferred to the cure reactor. Compost is also withdrawn daily off the bottom of the cure reactor and conveyed to trucks for transport off-site. As the ma terial moves in a plug flow fashion from the top of the bioreactors to the bottom of the cure reactor, bacteria and fungi consume the organics in the mix as they grow and replicate. Heat is produced by the growth of the micro-organisms, quickly raising the temperature of the compost mix in the reactors. The tem perature ranges between 40 and 60 de grees Celsius for the 28 days of mate rial residence time within the facility. Temperatures of 55 degrees or greater

warm and moist, from the top of the compost reactors and maintain a slightly negative pressure within the reactors to ensure no escape of odours,. These offgases are passed through an air-to-air heat exchanger, where the heat is recov ered and used in the building during winter months. The off-gases are sub sequently diffused into the WWTP ac tivated sludge aeration tanks, where any odourous compounds are neutralized.

the receiving bin, the amendment is ei ther conveyed to a hammermill for size reduction or the hammermill is bypassed and the amendment is pneumatically conveyed directly to the amendment storage silo. Damaged wooden pallets which have been ground up are typically used as an amendment source; however,

larger wood chips, which can be recov ered in the screening system, may also be used.

A screening system, consisting of a flexible perforated mat, has been incor porated to allow the final product to be screened prior to discharge from the fa cility. The mat allows smaller compost particles to fall through the perforations during agitation of the mat, while the larger particles continue to travel off the end of the mat. The "overs" from the

screen are typically larger wood chips, which may be used again in the proc ess. These are metered out of the recy cled chip storage bin and blended in the mixer with the sludge, amendment and compost recycle. The material that passes through the mat of the screen is conveyed to trucks for transport off-site. City of Guelph Works Department data provided by CH2M Gore and Storrie Limited. Conclusion

The two plant profiles provided il lustrate that composting is an effective method of producing useful biosolids from sewage sludge, treated alone, or in a matrix of other organic residuals. The two approaches to design, technology, and implementation indicate room for creativity and cost-effectiveness. If each existing and anticipated fa cility is operated with end-product qual ity as its focus, and if systems are in place to preclude potential impacts to the local community, then composting can help to achieve local waste diversion goals while providing a source of valu able organic soil amendment products. Composting,along with alkaline stabili zation and heat drying/pelletization can produce marketable products which will offset the cost of production. In order for marketing to occur and expand, we will need to develop a regulatory frame work which supports the merchant ability of these useful products, and builds public confidence which will lead to their acceptance in the marketplace.

sides of ozonation

Though news reports have focused on ozone as a

serious air pollutant, this oxygen variant has a good, lesser known side. When generated artificially and applied under controlled conditions, ozone can solve a number of pressing environmental problems. Over the years, ozone research sponsored by the(US)Elec tric Power Research Institute (EPRI) has branched into a

variety of areas, exploring ozone's effectiveness as a disin fectant for drinking water, as a bleach and detergent substi tute in large-scale laundry facilities, and as a way to treat VABCOtW'

several kinds of industrial wastes.

But perhaps one of the most dramatic EPRI-instigated achievements on the ozone front is an expert panel's recent

affirmation of"generally recognized as safe" status for ozone as a sanitizer or disinfectant for foods. This affirmation was

delivered to the FDA and cleared the way for ozone's use in the(US)$430 billion food processing industry. Ozone can be used as a gas to disinfect a room for food

Ozone's health and environmental benefits are working to

secure it a place in a wide variety of other markets. More than 200 US drinking water plants use ozonation and the number is expected to climb rapidly. Ozone is far more ef fective than conventional disinfectants against the microbial contaminants - including Escherichia coli, Salmonella, Giardia, and chlorine-resistant Cryptosporidium - that have invaded food and water supplies and claimed numerous lives in recent years. Ozone isn't always used as a disinfectant in water treat ment. It can also be used as an oxidant. In fact, the city of Orlando, Florida is building five full-scale plants to oxidize hydrogen sulfide, which causes "rotten egg" taste and odour problems in the local water. There is, however, ample opportunity to improve the effi ciency of ozonation, especially in the way it is deployed. In an ongoing ozone optimization study,EPRI is assessing ozone systems in drinking water treatment plants across the coun try. Goals include helping plants determine coiTcct dosages of ozone, improving the energy efficiency of ozone systems, and developing design standards for new plants deploying ozonation.

In an entirely different water-based application, ozonation has been used to recycle saltwater in aquarium environments, where water discharge can contain brine, excess food, and animal waste. To encourage this use of ozone, EPRI and the New York Power Authority helped sponsor a demonstration of ozonation at the Central Park Wildlife Center in New York

City. The system, which was used to purify the water habitat of polar bears, penguins, sea lions, and other animals, per formed well during a year-long pilot and, as a result, was installed as a permanent system. ■

Jet Fuel Infrastructure

By Greg Baker and Bill Penny

Rebuilding ofjet fuel infrastructure at Pearson International Airport

The Greater Toronto Airport Authority (GTAA)released a Terminal Development Master

Plan in March 1997, which

outlined in detail the proposed redevel opment of Lester B. Pearson Interna tional Airport(LBPIA). The Master Plan consolidates both

Terminals One and Two into a single ter minal building. It also includes the demolition of the existing cargo facility and the construction of a new cargo processing area within the infield, dual taxiways, an additional taxiway that will surround the entire terminal complex as well as new runway construction. An ticipated cost for this massive redevel opment will be in excess of two billion dollars.

Existing combined facilities of Ter minals One and Two have a total of 78

bridged gates and 17 commuter posi tions. The new terminal will be designed with 130 gates and will be capable of handling 45-50 million enplaned/ deplaned passengers per year.

He writes: "The least controversial expla nation of the warming observed over the past 130 years or so is that it is a return to normal from the Little Ice Age, and possibly, an entry into the next warm period." Ellsaesser points out that even the Intergovernmental Panel on Climate Change(IPCC)concluded:'"The Little lee Age came to end only in the 19th century.

The study argues that global warming is largely attributable to the Earth's naturally-occumng and cy clical climate change pattern. In Global Climate Science Is Still

global warming and cooling, and illus trates the cyclical nature of the earth's changing temperatures. "We are cur rently in an interglacial period, which

He notes that over the last 1,000 years, the earth ex perienced both warming and cooling trends, including the most recent cold period from about 1450 to 1900 AD known as the "Little Ice Age". According to Dr. Ellsaesser, the fact

"Global climate policy may have reached a crescendo in Kyoto in Decem ber, 1997 but it will not be because a

warming is well established, models of humans'contribution to the greenhouse effect are less well formulated. Ellsaes

We do not yet know what the de tailed 'signal'[fingeiprint] looks like be cause we have limited confidence in our

Whenthe Ontario Ministry

of Energy and Environ ment (MGEE) incorpo rated site-specific risk as sessment(SSRA)into their 1997 Guide line for Use at Contaminated Sites, an excellent opportunity was created for land owners, financial institutions, in

A site specific risk-based approach offers nu merous advantages over site cleanup to generic soil quality standards, most no tably by providing a greater flexibility in site management alterna tives and,consequently, greater proponent con

In respect of cleanup liability, by re quiring that a Certificate of Prohibition be registered on title to the piece of land in question, the SSRA option does not in itself remove the issue of land blight.

Firstly, it is essential that the propo nent understands the underlying philoso phy of risk assessment, i.e., as a frame work for identifying, understanding,dis criminating between, prioritising and managing human and ecological health risks.

Focus on Site Remediation

By Rene de Vries, B.Sc.

Is Ontario winning the site redevelopment race?-An industry perspective

When the Guideline for Use at Contaminated Sites was introduced in Ontario in 1996 after

more than two years of public consul tation, it was compared to a new racing car that would likely require some tinkering along the way in order to work properly. The Globe & Mail reported, some what optimistically in July 1996,that the Ontario Guideline would likely increase urban renewal because it provided land owners and their consultants with more

criteria, advice, and flexibility than did the previous Guidelines, developed in 1989. But in September 1996,the Daily Commercial News reported that con taminated site redevelopment in Ontario was in limbo because of fear of liability and risks. It is now time for a perform ance review and for a look at the road ahead.

Economic Driver versus

Regulatory Driver Cost is a very important factor in any decision, including those concerning contaminated site development. This observation may seem obvious, but this kind ofcommon sense has, unfortunately, not always been applied in the site as sessment and remediation field. Corpo rations have sometimes learned the hard

way, that they cannot spend much more on any particular issue than their com petitors and still successfully compete in the market place in the long run. In an era where governments are less and less relied on for protection from these market forces, the economic driver

with the guideline as its racing car seemed the logical tool of choice to tackle the contaminated site redevelop ment race. Ontario bought into this ap proach. However, Ontario's counter parts in British Colombia decided to pass a law (Bill 26) to deal with the is sue of environmental protection in the area of contaminated site redevelopment and let the regulatory driver do its work. These different approaches reflect the philosophical differences between the two parties in power in these provinces. It is fascinating to see the results of the two different regulatory regimes in this area. It is a bench-scale test of what

vironmental management: the economic driver or the regulatory driver, or the car rot versus the stick approach. The former Minister of the Environ

ment in the Netherlands, Peter Winsemius, conducted detailed studies on the

issue of effective government and envi ronmental management. He concluded that if everything else is equal, people and, therefore, corporations respond better to positive stimuli than to nega tive (punitive) stimuli to get the envi ronmental protection job done. Yet he also concluded that in order

would expect that Ontario would be the winning contender in this race. Tinkering along the way That there is more to winning a race than having a shiny new car became clear rather quickly. If there are obsta cles on the road, it may be hard to reach the finish line at all, let alone win a race.

The Daily Commercial News was right: one of these obstacles is the issue of al

location of environmental liability and risks. To elaborate on the metaphor used,let's compare environmental liabil ity to a pool of slippery oil on the race track surface - a formidable challenge

When there are no responsible par ties, such as Imperial Oil, the biggest horror story in the contaminated lands saga in Canada develops: orphan sites. Estimates of the number of these sites

in Canada vary from 3,000 to 30,000. There are no responsible parties to be found. They have either gone bankrupt, moved on to their next money-making enterprise, and/or are not taking respon sibility for their actions in other ways. These contaminated sites will eventu

ally wind up on the books of our gov ernments, transferring private responsi bility and accountability to the public's domain.

The Guideline for Use at Contami nated Sites in Ontario has provided a good general framework that will need some additional tinkering down the road in order to work properly. One of the uncertainties related to the process the MOE envisioned will hopefully end now the status and wording of the Record of Site Condition has received clarification.

Ongoing efforts to clarify the roles and responsibilities of the parties involved, and the continued introduction of gen erally accepted and affordable rules, processes, and standards are essential. The Guideline has not so far resulted

in a race to clean up contaminated sites

in Ontario due to a lack of financial in centives and the risks and uncertainties involved. An economic driver will not

do the job if there are no financial in centives or if the risks are too big. Even though using the economic driver in stead of the regulatory driver is likely the preferred way to tackle the issue of contaminated site redevelopment, it re mains to be seen if the market forces will

create enough financial incentives on their own for responsible parties to take action. If not, governments and corpo

rations may have to start looking at ways to create these incentives and reduce the risks and uncertainties related to con

taminated site redevelopment. Orphan sites may become the biggest challenge our society will need to come to grips with in the area ofcontaminated

Water Supply

Water supply to Cono Norte and you thought you had problems

TheCity of Lima is the capital of Peru, with a rapidly grow ing population currently

pegged at about six and a half million. Water supply is provided by a combination of groundwater and treated surface water taken from the Rimac River that flows from the Andes. Con

trary to any preconceived notions you might have about these snow capped

Andes with the ultimate goal of supply ing more of the city from La Atarjea. This is where Delcan entered the pic ture on a $L2M project funded by the World Bank.

Delcan's task was to model the north

end of the city, assuming a gravity sup ply from Atarjea via an extension of an existing 1600 millimetre diameter watermain.

The model is shown

water demand of 2.3 cubic metres per second or 43.5 million gallons a day. The region is currently supplied by fiftyseven wells drawing from a declining resource and demand outstrips supply by an ever-widening margin. Despite the shortages, people continue to flood into the area and the city has been un able to stem the tide. The best they can do is ensure that each new development has its own system of wells and an el evated "head" reservoir paid for by the developer. The economics are perhaps

Groundwater is the only option for supply to the city's fringes because every drop of water from the Rimac is already spoken for. The entire Rimac flow is diverted to La Atarjea water treatment plant as it enters the city, leaving a bone dry river bed downstream until it mys teriously begins to flow again before it enters the ocean. One suspects that raw water quality is a little poorer than that upstream of the plant-enough said! As the city grows therefore, the pressure on groundwater increases and the water ta ble is falling rapidly, leaving well pumps high and dry. In areas close to the
