Passenger ships are like great floating cities, gene rating vast amounts of putrescibles, packaging, hotties and cans; exactly the same kind of trash that land-based communities generate. Basking in the tropical sun, we would see crewmen heaving large containers of garbage over the stern, where it floated in the foaming wake of the ship's propellers before sinking beneath the waves.

Nitrogen Propelled Barrier packag ing provides a number of benefits to both the consumer and the environ ment;

In addition, the inner con tainer inside the can completely disintegrates during the recycling process and therefore will not con taminate the recycled steel. • End product can be dispensed in any orientation — upright, upsidedown or sideways — with no danger of losing propellant. Pure Air Spray will be customfilling the barrier packages at the 15,870 square foot plant.

A substantial number of water meters are also being installed for the first time.

The replacement project is using manual open cut techniques. Note the shallow depth of the pipe (approximately 18" in this case) which would certainly freeze in Canadian winters. The contractor used only picks and shovels to dig up and replace the water services right into the home.

Management Strategies

Establishing protocols for large decontamination projects

Large decontamination pro

jects raise serious logistic problems. Whether it be a major chemical product spUl in a sensitive area,the contami nation of groundwater used as a drinking water source or the pres ence of carcinogenic substances in a working environment following a fire, decontamination situations are so important and urgent that enlightened decisions have to be consistently made. The project manager faces sev eral choices;

•act immediately or examine the problem in more depth? • destroy or remove the contami nants?

•process wastes in situ or dispose of them elsewhere? •choose which measures should be

taken to protect the health and safety of all individuals and workers involved? •hire someone or call for tenders?

The success of the operation — as well as the cost involved — depends on the answer to these questions. Four main points must be consi

By Jean Paquin* situation can also have serious det

rimental consequences. The correct approach is one that halts or limits as much as possible the spreading of contaminants, one that involves mobilization of the

necessary resources and one that does not limit the scope of remedial measures that may be initiated afterwards.

Health and safety The next point to be taken into consideration is the one related to

the protection of those workers or individuals who could be affected by the contamination, once the project is in its realization phase. It might be tempting to set up maximum safety measures. Never theless, such an action can prevent actual implementation of the pro ject. For example, it would be use less to protect the individuals to such an extent that the daily doses

Depending on the decontamina tion process selected, a water, air or waste treatment station is normally required as soon as the project takes on a magnitude that goes beyond certain proportions. In several cases, managers had a limited knowledge of the available technol ogies or a limited grasp of the opti mum logistical approach, and clean-up operations have been more costly than necessary. A zoning system should be estab lished and strictly adhered to, according to the nature and concen trations

involved and the progress of the clean up operation. The zoning sys tem should be designed to minimize the amount of required decontami nation work and to avoid recontami-

defined for that is where effective ness and cost factors are most sensi tive.

Rapidity of action The project manager must first evaluate the urgency of the situa tion. A delay ofseveral hours before intervention might increase the clean up cost ten-fold in the case of an accidental spill on a water body. In the case of a land spill, a two month delay for calls and study of tenders can also substantially increase the clean-up cost. On the other hand, hasty measures taken without sufficient analysis of the

Clean up of the area may be achieved for example by lixiviation of the contaminants, biodegradation, solvent extraction or by physi cally removing the contaminated material. The best approach could consist of stopping the contamina tion through a chemical fixation process, or to confine the spill. All options should be looked at, without prejudice, in the initial part of an urgent clean-up project. Any large project must be based on an analy

Infrastructures

The next problem deals with the infrastructures required on the site, i.e. headquarters, communications and documentation, staging areas, workers' quarters, control of access, and the equipment decontamina tion section. In the absence of these

infrastructures, progress of the dec ontamination activities may evolve in the wrong direction. In clear lan guage, the clean up period will be much longer than necessary and the clean-up will most likely cost more than it ought to. As an example, let us consider a PCB fire within a large building. In the case of a fire, the PCBs will

form into PCDFs(furans)and possi bly PCDDs (dioxins), though in lesser quantities. These products are much more toxic than the PCBs

and their permissible concentration levels in a working environment are consequently very low. *M. Paquin is Director, Technical Services, Sanexen International Inc.

has focused largely on the traditio nal"end ofthe pipe"solutions to the problems of municipal wastewater treatment. A paper by Inland Waters Directorate scientists R. Rivers and R. Kalinauska in Water

Science and Technology attempts to place one "at source"solution, water demand management,into the con text of the remedial action plan. Fully developed relationships bet ween volumes of water usage and the quality of sewage treatment facility effluent have not yet recei ved an adequate degree ofinvestiga tion. Nevertheless, ample evidence is available to suggest that water demand management is the most cost effective method for remedia

tion of municipal water pollution in Hamilton Harbour.

Volatile Organic Contaminants Removal

In a joint research study, H. Melcer of Environment Canada's Waste-

water Technology Centre, former CH2M Hill scientist S.G. Nutt, and Ontario Ministry of the Environ ment's H.Monteith operated laboratoryscale activated sludge treatment systems under dynamic loading conditions to investigate the nonsteady state behavior of volatile organic contaminants (VOCs) under controlled conditions. Four

step tests were conducted in which an incremental increase in the con centrations of selected contamin

ants was applied to the reactor feed up to 0.1 mg/L. As described to delegates attending the lAWPRC biennial conference in Kyoto, diffe rent mechanisms are responsible for the removal of short-term, nonsteady state inputs of chlorinated and non-chlorinated VOCs. Control of Wastewater Treatment Plants

A paper published by McMaster scientists G.G.Patry and I Takas in Advances in Water Pollution Control describes the basic elements

of simulator-based technologies for the analysis and control of wastewater treatment plants. Emphasis is on the development of a General Purpose Simulator for wastewater treatment plant modelling. The GPS consists of two major compo nents: a) a screen-oriented model ling interface allowing for the gra phical specification of the process flow sheet based on object-oriented concepts,and b)an interactive simu lation interface designed to provide control of the simulation as it pro ceeds. The GPS has been applied to

Concentrations of heavy metals and phosphorus were measured by T. Mayer and P.G. Manning in sus pended solids collected from Hamil ton Harbour. Two iron forms, wustite and hematite, originating from anthropogenic activities were iden tified in addition to naturally occur ring iron from chlorite, clays, and amorphous iron oxides. These National Water Research Institute

scientists reported in the Journal of Great Lakes Research that the high est metal concentrations are found

in deep water and in areas adjacent to outfalls. Heavy metals in sus pended solids exceed guidelines for open water disposal of dredged sedi ments. Manganese and iron were released from bottom sediments dur

ing summer anoxia in the hypolimnion of the deep water. Groundwater Vulnerability Mapping A paper published in Sciences et techniques de I'eau by D. Isabel, P. Gelinas and F. Auhre describes the

mapping of groundwater vulnerabi lity using the U.S. DRASTIC com

puterized program. A test case sample mapping of the Regional Municipality of Desjardins County is described by these Laval Univer sity Scientists. The analysis of this test case shows that the DRASTIC

vulnerability index can he improved and adapted to Quebec hydrogeological settings. Dechiorination of Chiorophenolic Compounds

Laccase-type phenol oxidases are the principal oxidative enzymes secreted by the white-rot basidiomycete Trametes (Coriolus) versicolor. Numerous reports indicate that these laccase enzymes can oxi dize, polymerize, and, under some conditions, cleave a wide variety of biological and synthetic phenolic compounds. Pulp and Paper Re search Institute scientists L. RoyArcand and F.S. Archibald treated

kraft bleachery effluent with the laccase protein fractions secreted by T. versicolor. As reported at the BIOFOR/BIOQUAL '90 confer ence, they found that the crude enzyme can account for most of the observed chiorophenolic degrada tion carried out by the complete organism. Each of the fungal lac case proteins tested can rapidly par tially dechlorinate a number oftoxic polychlorinated phenols and guaiacols.

They are used commercially as pes ticide constituents in marine anti-

fouling paints and as additives in various PVC plastics. Recent research work carried out by Natio nal Water Research Institute scien tist B.F. Scott has resulted in the

development of a protocol for the determination of butyltin species in environmental samples using a gas chromatography-atomic emission spectroscopy system. With this method,it is possible to detect butyl tin species in fish and sediment samples at the low parts per trillion level.

Nutrient Removal from Lagoons Scientists from the University of Sherbrooke, Gendron Lefehvre Inc., and Environment Quebec conduc ted laboratory and on-site studies on an aerated lagoon treating domestic wastes. K.S. Narasiah, C. Morasse and J. Lemay used alum and ferric chloride for nutrient removal. As described in Water Science and

Technology alum reacted preferen tially with polyphosphates and with orthophosphates in the precipita tion process. Seasonal temperature variations did not appear to affect the coagulation and flocculation process adversely. The molar capa city of alum for precipitating the orthophosphate fraction was grea ter with secondary treatment than with primary. The phosphorus removal efficiency varied between 90 and 95 percent with both coagu lants.

Hydrocarbons in Ground Water Scientists from Gartner Lee Limited

and the University of Waterloo de tected benzene,toluene,and xylenes in ground water during a contami nant hydrogeological investigation of a landfill site. The landfill site

was situated on approximately 10 m of clay and glacial till overburden soils, which were underlain by a shaly limestone bedrock. Although it was initially thought that the landfill was the source of these con

taminants, D.D. Slaine and J.F. Barker showed that the hydrocar bons could be leached from the bitu

minous layers of shale that were interbedded in limestone.

According to Dr. Oilman, who has done extensive research into the health effects of PCBs with the Health Protection Branch of Health

and Welfare Canada, "scientists

generally agree that short-term, low-level exposure to PCBs is unlikely to have a significant helath impact." Dr. Safe, a Canadian who leads the Department of Veterinary Phy siology at Texas A&M,said several studies have indicated that past alarm and public fear concerning PCBs were to some degree, unfounded.

"At present, there is no evidence which suggests that PCB exposure in the workplace results in increased mortality or cancer," said Dr. Safe. "However, there are data which indi cate that prenatal exposure to envir onmental toxicants may cause developmental problems in the offsp ring and this is an area of research which requires further study."

"There is no

question that this has lead to uneven and sometimes inaccurate

coverage ofPCB issues and this has lead to fear and suspicion of all PCB issues in the public."

Society (LIS) Air Program focused on reducing ambient levels of etbylene, and developing methods to trace and eliminate unpleasant odours in Sarnia's Chemical Valley. Bob Sones, plant manager at Du Font's Corunna manufacturing plant and a chairman of the LIS air committee, unveiled the news at the Society's 38th annual review meet ing. Though greatly reduced since the 196Gs, Sones said odours still remain a concern in this area and

solving the problem will be complex and costly. "Technically, we believe this will be the air challenge of the

According to Sones, this ability to detect low levels of certain com

pounds, particularly in the early morning, has caused some people to accept the suggestion that Valley companies release these gases only at night. "People think they (com panies) open the pollution valve at night," said Sones. "In some ways we (the LIS) wish it were true," he added. "Stopping odours would be a relatively easy task of finding the valve and shutting it off." Although current levels of ethylene,(a chemi cal building block used extensively by local companies), pose no threat

one percent of all the wastewater treatment plants have solids incin eration, and this percentage is lower in the rest of the country. At least 15% of my exam was either directly or indirectly based on solids inciner ation. There was such a heavy pre ponderance of the process questions based on solids incineration that by necessity, more common processes were totally left out ofthe exam. For

example, there wasn't a single ques tion on either lagoons or aerobic digesters. It is now very clear why Ministry of the Environment level IV opera tors have done so poorly on their

that there would be plenty of time. This advice came from the W.P.C.F.

My colleagues, whom I questioned on this point, found that they also could not com plete this exam on time. There was no time to recheck any questions. In themselves the math ques tions were not difficult, however, they ate up far too much time. The paper allowed 1.8 minutes per ques tion. Many of the math questions couldn't be read in 1.8 minutes, let alone answered in that time. Sev

anybody conduct a time study on this exam, and if so, on what basis? Future WWT IV exams are going to have to be more realistic with

respect to the quantity of math ques tions in relation to the available

time. I would suggest the quantity of math questions more into line with the Water Pollution Control

Federation's study guide, the pro cess questions should reflect all level IV plants, not just those with incineration.

Water Treatment

Process modifications improve the Wanapitei Water Treatment Piant

Modifications to water treatment processes and upgrades of plant and pumping facilities at the

Wanapitei Water Treatment Plant have eased a water supply problem in the City of Sudbury. A signifi cant decline in the water level of

Ramsey Lake in 1987 reduced the

ability of the Sudbury System to meet demand.

Some modifications to the plant's processes were required due to new developments in technology and plant operation difficulties. To speed up the modifications,the over all scope of work was split into a series of consecutive contracts. This allowed for construction to take

place through one contract, while the design of the following contract proceeded at the same time. The first contract awarded was

for the replacement of the filter media in the existing filter boxes and supply of the media and underdrain system for equipping two unused filter boxes. Changing the

filter media in the existing two fil ters alone, permitted plant produc tion to increase from approximately 22,700 mVd(5MGD)to 31,800 mVd (7MGD), an increase of 40%. Subsequent contracts called for installing equipment in the unused filters; supply oflow lift and high lift pumping units, standby diesel gen erator sets and switchgear;installa tion of prepurchased equipment; modifications to waste handling; and, building modifications to pro vide new office, lunchroom and meeting areas, as well as changes to meet current codes.

The pacing system for chemical addition was changed to a continu ous feed system, which is paced directly by the incoming flow. The pre-chlorine injection point was moved to a location ahead of injec tion points of all other chemicals. This allows for addition of chlorine/ chlorine dioxide to the raw water

and the monitoring of its residual

before any other chemicals are added.

Installation of a new flow propor tioning system solved difficulties with splitting and maintaining the flow between the two clarifiers. An ultrasonic flow meter and electric

operators on the flow control valves modulate and control the flow enter

ing each clarifier. A new mixing tunnel was con structed in the existing clearwell and a closed loop control postchlorine pacing system was pro vided for proper mixing of post chlorine solution and constant mon

installed to gather data from var ious points of the treatment process, and to command separate control devices to actually change condi tions at different stages of the pro cess. The control room operator is able to call up data on the computer screen for any stage or process in the plant. The operation of each remotely located pump at the raw water pumping station, or the Kingsway Booster Pumping Station on the dis charge main is initiated at the com puter. The control room operator can make adjustments through the computer to set-points of chemical feed pumps, or change the flow rate through the new filters. Backwashing of the new filters is automati cally sequenced following manual Full automation of the

plant was not undertaken because of the cost involved in updating all existing equipment, and also because the plant is manned 24 hours a day. The Wanapitei Water Supply System was developed in 1973 to increase the capacity of the City of Sudbury System in response to growing demand for water, and to supplement the Ramsey Lake source. Drawing its water supply from the Wanapitei River, the plant is approximately 10 km east of Sud bury on Highway 17. The raw water intake is an additional 3.5 km east of

the plant, and the intake pumping station delivers water to the plant through a 750 mm diameter main. 'Manager, Water&WastewaterTechnology, The Proctor & Redfern Group

Business and the Environment

A Partnership or... a $10 Miliion Lawsuit? Every business must recognize situations potentially dangerous to the environment and comply with the regulations established to protect our natural resources. When you need help, do you know where to turn? Have you complied with the regulations? Do you need government approval or an environmental assessment? Do you have a problem with contaminated land or with waste transportation and disposal? What are your civil remedies? If you have responsibility for environmental issues in your organization, you should already know the answers, or where to find them.

combines mixing, clarification and thickening in one compact unit, cutting your capital and operating costs substantially. External sludge recirculation produces the dense sludge for which the Densadeg is named — a much reduced volume of solids so well conditioned that it can be

directly dewatered.

Versatile Densadeg systems are being used everywhere for such varied applications as water treatment, wastewater reuse, and heavy metals removal. The Densadeg can defy the gravity of your water treatment problems! Need clarification?

Ask yourself this.."Do my test results balance?... Are they complete?"... or . . . don't you really know! At MANN AQUA we know! Quality comes first because our expert system says so. And to prove it, we give you all of your theoretical Quality Control data so you can see for yourself just what your water is or is not missing. It's really quite simple: our computer checks the ion balance. When the cations and anions (-F and -)are not equal, either an anaiytical error exists which we'll correct before it leaves the lab, or something is in your sample which has not been tested for; in either case the theoretical conductivity pinpoints the solution. So if you didn't know what you were missing before . . .

NOW YOU DO.

Where there is a need to monitor

Sampling and testing wastewater often provides companies with valuable process information. By Peter Smith, Epic Products UK, and John Coomey, Cancoppas Ltd.

Companies are increasingly

aware that sampling their wastewater can provide valu able information about production efficiency, often providing an indi cation of where savings can be

made. So it is inevitable that sam

pling will assume an increasing vital role in industry. Sophisticated sampling techniques will be requi red to provide the data necessary to satisfy the new criteria. In the late 1980's, Ontario, like many industrialized areas, was faced with the challenge of dealing effectively with the level of toxic contaminants that threatened

aquatic life, public health and drin king water quality. The growth in knowledge about the risks posed by certain com pounds, even at very low concentra tions, prompted authorities to tackle the problem with vigour.

T^e result was MISA, the Muni

cipal /Industrial Strategy for Aba tement with its stated aim of stop ping water pollution at the source. Contaminant indicators such as

level of suspended solids, COD and BOD were of course, of interest, but they can provide information about only simple pollutants such as Phe nols, PCBs, Cyanides, and so on. As well as this, they needed to detect extremely low levels of these and other toxic contaminants with high accuracy.

is to reduce the level of persistent toxic contaminants to as near zero

as possible within the constraints of practical measurement of contami nants. Consequently, the regula tions refer to the use of Best Avail

the discharge over specified conse cutive time intervals, for example, it provides a bottle grouping facility. A group of bottles are addressed, for a period of say a day, followed by the adjacent set of bottles being addres sed for the next period. This is extremely useful in providing divi ded composite samples over a wee kend for example. The use of inert materials such as

glass, stainless steel or PTFE for the wetted parts of a sampler, solves the problem of analysis results being distorted by the material of the unit. This development also resulted in profound modifications being made to the mechanical design of the sam pler. The Epic system can be used either in a portable form â&#x20AC;&#x201D; ideal for industries new to sampling who need to assess the most suitable

sampling point â&#x20AC;&#x201D; or as a fixed sys tem installed at the points identified for regular sampling. Pollution legislation and dis charge sampling in Ontario have now overtaken that in the U.K. The new Environmental Protection Bill

will ensure that the most sophistica ted sampling techniques will be used in future developments.

Big 'O' solution for PCB problems Big '0' Inc. is offering a unique imbibing polymer product as a solu tion to PCB problems. Expanda-

beads, lightly crosslinked polymer beads, are chemically engineered to absorb a wide range of organic fluids, including PCBs. Cross-linking prevents the beads from dissolving and instead causes them to swell as they absorb, as much as twenty seven times their original volume. Expandabeads differ from adsorbent products cur rently in use in that they entrap a compatible liquid within their molecular structure, rather than merely spreading it across surfaces. The end product is an easy to handle

solid. Organic fluid cannot be removed from Expandabeads once absorbed. A fully swollen bead can even be chopped up without releas ing fluid. To promote faster absorption and rapid penetration of liquid to all beads, they are blended with a wicking material. This product is availa ble in pouches and pillows, for fast cleanup of spills, and in hulk for solidification of liquids - for trans port and safe storage. Big '0' Expandabeads are nontoxic and extremely inert, but should be treated with the same

respect as the material they have absorbed. Big 'O' Inc.

In addition to the engineering challenges.Ford,Gore & Storrie,and the Regional Municipality of Halton, along with the Ontario Ministry ofthe Environment, had to engage in pro tracted negotiations to ensure that the project was both governmentally acceptable and viable from an envi ronmental engineering standpoint. The result was an evaluation, approval and design process that serves as a prototype for other indus tries now required to comply with MISA. The plant was successfully

Typical of the many problems to be overcome was the need to demon

stream for reprocessing. One ofthe many innovations was a modified cake-breaker to intercept the sludge discharge as it falls into dumpster boxes from recessed plate filters. The cake-breaker comprises twin counter-rotating auger-screws with multiple discharge ports. This eliminates sludge jams while in creasing the density of dump loads. Another challenge was to build this modern facility while keeping the existing lagoon treatment sys tem operating efficiently. Mixed chemicals and wastewater were treated and directed to two earthen

impoundments for settling, al lowing treatment to continue while the new facility was constructed. The auto assembly plants and treatment facilities were in an

Each pump is driven by a 335 kW (450 H.P.) variable speed motor. Standby power for the station is provided by two 565 kW (760 H.P.) diesel generators. Another unique energy saving feature is the compu ter control ofthe generators to "peak shave" thus reducing power costs during peak demand periods. The sewage is pumped through individual 750 mm (30 inch) dis charge pipes to the header gallery where they enter a 1200 mm (48 inch)forcemain. Future station dis charges will be to the Water Pollu

One of the more unique safety fea tures is the provision for the opera tions staff to continuously view the dry well pump floor (in order to detect a flooded condition) while descending in the elevator by observing conditions through the elevator's "glassed front wall panel".

Other safety features include automatic monitors for combustible

Operation Description During the 4-month winter stor age period, sludge from the Region's other WWTPs is trucked to the

remote transfer station, unloaded, and then pumped through the pipe line to the lagoon storage facility. During the spring/summer period, when landspreading of the sludge recommences, flows are reversed in the pipeline to the transfer station for truck loading. When the storage facility is dormant, the transfer sta tion is used for Kitchener's sludge alone, calculated to be 52 percent of the total Regional sludge volume.

Lagoon Design Three of the existing six sludge lagoon cells at the Kitchener WWTP were expanded to provide a total storage capacity of 200,000 m^, incorporating the most up-to-date design technologies. The work consisted of:

•excavation and removal of sludge accumulated at the bottom of the

existing cells and removal of berms

which were not structurally sound. • construction of a one-metre thick

floor using imported clay, with a permeability coefficient of 10-'' cm/sec.

• construction of new, elevated

berms of imported structural soils. The berms were lined with a buried

Lagoon Pumping Facilities A lagoon dredge pumping system was selected to excavate, slurry,and transfer sludge out of the storage lagoons, with a design flow rate of 359 m-'/hr. The'Mudcat'dredge and onshore booster pumping station, with a combined driver rating of300 hp, provide the total dynamic head required to pump sludge to the transfer station. The dredge and booster pump are both variable speed systems and operate in series. The dredge operator selects a setpoint flowrate and the booster pump, using a suction pressure con troller, automatically provides the additional head required to transfer sludge to the transfer station. The lagoon pumping facilities were com pleted in May 1990 for a construc tion cost of $700,000.

Sludge Pipeline The sludge pipeline serves two purposes: to transfer sludge from the transfer station to the lagoons during the winter storage period; to transfer sludge from the lagoons to the transfer station during the spring/summer period. Constructed of 400 mm diameter,

series 160, high density polyethy lene (HDPE) pipe, the 2.7 km pipe line was equipped with pig cleaning launchers and catchers to provide routine cleaning services. Pipeline air

chambers located near public areas were constructed with activated car bon canisters to control odours. The

pipeline also contains a pneumatic surge control vessel to protect the pipeline from excessive positive and negative pressures during extreme operating conditions. A major element of the pipeline design was routing of the forcemain through an environmentally sensi tive area near the Kitchener WWTP

by inserting it in an abandoned 1200 diameter sanitary sewer. This pre vented damage to a treed park area adjacent to the WWTP. The pipeline was completed in September 1989 for a construction cost of $860,000.

Sludge Transfer Station Major components ofthe transfer station, located in Kitchener's industrial park area include: •Two enclosed transport truck bays equipped with fully automatic "hands-off truck coupling/uncou pling equipment. •Pumps to transfer sludge, at a rate of 240 mVhr, to a 1600 m^' onsite
