TECHNOL TRANSFER The Bridge Between Research and Use ENVIRONMENTAL PROTECTION AGENCY DESIGN MANUALS TO BE AVAILABLE AT WPCF CONFERENCE Four design manuals describing the tech- nology used for phosphorus removal, suspended solids removal, activated carbon adsorption, and for upgrading existing municipal wastewater treatment plants will be available to the at- tendees of the Water Pollution Control Federa- tion's annual conference to be held in San Francisco, Calif., Oct. 3 to Oct. 8, 1971. The design manuals were developed through con- tracts with various consulting engineering firms, with considerable technical input from the staff of the Environmental Protection Agency's Cincinnati Advanced Waste Treatment Research Laboratory. Contractors for the design manuals were: Black & Veatch — Phosphorus Removal Burns & Roe — Suspended Solids Removal Swindell-Dressier — Activated Carbon Adsorption Roy F. Weston — Upgrading Existing Wastewater Treatment Plants The design manuals can be obtained at no cost at EPA's Technology Transfer exhibit center in Brooks Hall of the Civic Auditorium. The exhibit will feature specially built displays of flow diagrams illustrating Physical-Chemical Treatment, Phosphorus Removal, and Upgrading Existing Wastewater Plants. Additional displays on Storm and Combined Sewers, and Federal- State programs will also be part of EPA's Technology Transfer exhibit. These design manuals provide detailed infor- mation on new treatment processes and techni- ques, along with their associated costs. Informa- tion is included on manpower requirements; case histories of municipalities using these new processes are also cited. It is felt that if engineers utilize the recommendations contained in these manuals when designing new or upgrading exist- ing waste treatment facilities, a major impact can be made on improving the quality of wastewater treatment. In addition, the manuals will provide guidance to engineers so that they will be able to advise municipalities on the best methods to meet present and future water quality standards. For those engineers who are unable to attend the WPCF annual conference, the design manuals will be available free of charge through the Technology Transfer committee located in their region. The names and addresses of the regional committee chairmen are listed at the end of this fact sheet. Covers of Design Manuals SUSPENDED CARBON ADSORPflON upgrading BdSUNG wmNm TREAIMM PLANTS ------- Additional design manuals on physical- chemical treatment, nitrogen removal, and sewer system corrosion control are planned for 1972 as part of a continuing series to transfer new technology as soon as it becomes available. All the design manuals will be constantly updated as appropriate. DESIGN SEMINAR PROGRAM CONTINUES The Technology Transfer design seminar program continued its tour through Charlottes- ville, Va., on June 8 and 9, and Dallas, Tex., on July 27 and 28, 1971. These seminars, planned to transfer new research findings to consultant, State, and local design engineers, included a first half-day session covering the EPA construction grants program and Federal Guidelines for Design, Operation, and Maintenance of Waste- water Treatment Facilities. Attendees were then divided into three groups, with each group participating in a separate technology subject area that had been selected to answer the specific needs of the region. The attendees received detailed half-day sessions on each specific subject. Each session included a brief summary of the specific problem and a technical discussion by a leading authority in the field, followed by a case history of a municipality using this new technology. The Charlottesville, Va., seminar included sessions on phosphorus removal, nitrogen removal, and the use of activated carbon for Working session at Dallas Seminar being addressed by Dr. Irwin Kugelman from EPA's Advanced Waste Treatment Laboratory increased organics removal. Feature presenta- tions were given by Mr. James Laughlin of Shrimek, Roming, Jacobs & Finklea, consulting Russell Culp addressing session on media filtration and carbon adsorption Albert C. Trakowski, Deputy Assistant Administrator for Program Review, Office of Research & Monitoring, being introduced as speaker at Dallas Seminar luncheon engineers on phosphorus removal; Dr. Clair Sawyer of Metcalf & Eddy, consulting engineers on nitrogen removal; and Mr. C. Donald Wood of Swindell-Dressier Co., on the use of activated carbon for increased organics removal. In addi- tion, each session included a presentation summarizing the specific problem presented by a representative from EPA's Cincinnati Advanced ------- Waste Treatment Research Laboratory. Case histories of municipalities using this new tech- nology were also presented. The examples cited were: Rocky River, Ohio,for activated carbon;., the District of Columbia for nitrogen removal; and Piscataway, Md.,for phosphorus removal. The Dallas seminar followed the same general pattern for these meetings, with technology presented on phosphorus removal, nitrogen removal, and media filtration and carbon treat- ment. The sessions included presentations from the following consulting engineers: Metcalf & Eddy; Shimek, Roming, Jacobs & Finklea; and Forest & Cotton. A highlight of the session on media filtration and carbon treatment was the presentation by Mr. Russell Culp, South Lake Tahoe, Calif. VIDEO TAPES NOW AVAILABLE AT EPA REGIONS The Technology Transfer Program is pre- paring an entire series of video tapes on waste- water treatment process systems and techniques. Each tape is presented by a leading authority in that particular field. The first of this series, which is now available, features Arthur Masse, Chief of the Municipal Pollution Research Program of the Advanced Waste Treatment Research Laboratory in Cincinnati, Ohio. Mr. Masse presents a technical discussion on acti- vated carbon adsorption. Other video tapes are being prepared and will feature such subjects as phosphorus removal, upgrading existing treat- ment plants, oxygen aeration, and nitrogen removal. EPA TECHNOLOGY TRANSFER BOOTHS TO BE A FEATURE AT ST. LOUIS The Annual Environmental meeting of the American Society of Civil Engineers (ASCE) will show the latest technology developments in the wastewater field with the EPA display booths. This show will essentially be the same as the one being introduced by EPA at the Water Pollution Control Federation annual meeting in San Francisco. Attendees of the ASCE meeting will have the opportunity to sign up for the new design manuals. FROM THE REGIONS - NEW TECHNOLOGY IN USE Following are several brief reports submitted by EPA's regional offices describing a few of the successful projects which have been supported by the Research and Monitoring Program of the Environmental Protection Agency, or which have been implemented as a result of new technology developed and demonstrated by EPA's Research Program. Specific information concerning individual projects may be obtained from the Technology Transfer committee in the region where the project is located. METRO SEATTLE, WASH. "Park Development With Wet Digested Sludge" — Region X Ultimate disposal of digested sludge is one of the more difficult problems associated with wastewater treatment. In July 1968, the community of Seattle embarked on a program to investigate and demonstrate the feasibility of utilizing digested wet wastewater sludge as a landfill material. The following requirements were established for the sludge: it must have proper settling characteristics; be capable of reducing its high water content; exhibit no undesirable interactions with underlying soil layers; and possess acceptable structural charac- teristics. This four-year study has examined all the above requirements and found that the digested wet wastewater sludge could provide adequate landfill material. METRO began actual fill operations this summer as a means of developing an urban recreational park land by filling an intertidal test area. This project is scheduled for completion in July 1972. METROPOLITAN SANITARY DISTRICT OF GREATER CHICAGO. "Hanover Tertiary Plant Studies" — Region IV In 1965, the Board of Directors of the District decided to devote one of their sewage treatment facilities to developing advanced waste treatment techniques for application to pollution control requirements throughout the District. The Hanover Plant was selected for this purpose. A 1-million-gallon-per-day (mgd) microstrainer system was placed in operation in parallel with a 1 mgd rapid sand filter system to evaluate effluent pollution procedures. The effluent biochemical oxygen demand of an average of 17.5 milligrams per liter (mg/l) has been reduced to an average of 3 mg/l while suspended solids have been reduced from 12 mg/l to 5 mg/l. The microstrainer occupies about 1 /20th the space of a rapid sand filter plant and costs about ------- 1/1 Oth as much. The microstrainer has been found to be highly reliable and provides low operating costs. While this microstrainer is believed to be the first of its size and type in this country providing tertiary treatment, it will soon be joined by a larger unit now under construction by the District at their Northside Plant. The new system will have 15 mgd capacity. CITY OF MARLBOROUGH, MASS. "Use of Metal Salts for Phosphorus Removal" — Region I The City of Marlborough, Mass., is currently having final plans and specifications prepared for a two-stage activated sludge wastewater treat- ment facility with a design capacity of 5.5 mgd. Phosphorus is to be removed by the addition of a metal salt to the effluent of the first-stage aeration tanks. This plant will replace an existing high-rate trickling filter plant which discharges its effluent to a string of several small ponds and brooks before discharging into the main water course. The use of existing trickling filters for such treatment was eliminated because of odor problems, adverse effects of cold weather, and the need to maintain the quality of the effluent as high as possible. Metcalf & Eddy Engineers, Inc., of Boston are designing the facilities. Results of preliminary studies on this facility along with Metcalf & Eddy's experience on phosphorus removal were presented at the Technology Transfer Design Seminar held in Boston on May 26 and 27,1971. ROY WESTON, INC., "Design, Construction and Operation of a Transportable Advanced Waste Treatment Facility" — Region III Through a contract with Roy Weston, Inc., a relocatable wastewater treatment facility that is designed to handle 75,000 gallons of wastewater per day has been constructed and erected in Fairfax County, Va. The purpose of this facility is to provide an interim treatment system for new subdivisions until the subdivision can tie into the centralized treatment system. The unit will then be relocated at another developing subdivision so that homebuilding will not be delayed because of inadequate waste treatment systems. The treatment scheme utilizes flow equilization, ferric chloride addition to primary clarifiers for phosphorus removal, aeration, biological denitrification, multimedia filtration, and chlorination. The goals of this facility are to achieve the proposed Potomac River effluent standards for 1976, which are: Biochemical Oxygen Demand — 0.04 lb/1,000 gal/day Phosphorus - 0.0017 lb/1,000 gal/day Nitrogen — 0.008 lb/1,000 gal/day Start-up operations began this summer. Plans are for the County of Fairfax to take over plant operation in the fall of 1971. After operating the plant for one year, and if funds are available, it is planned to relocate the treatment facility within Fairfax County.
