INDUSTRY TRENDS Teradex Corp. (Walnut Creek, CA) announced a new service for environmental monitoring of radioactive radon and its “daughter” isotopes and elements for uranium exploration activities. The firm used Track Etch@ tech no logy . Acurex Corp. (Mountain View, C A ) will perform for EPA an environmental assessment of stationary combustion sources firing a variety of fuels. NO, and other pollutants will be emphasi7ed. Contract value: $850 000 over one year. Duke Scientific Corp. (Palo Alto, CA) is offering an expanded line of 0.1900-p analytical reference particles. These partjcles are asbestos, polystyrene, alumina, a.nd many other materials. There are pollution control applications. Zimpro Inc. (Rothschild, WI) is supplying systems to treat municipal/industrial wastewater a t Mt. Holly, N J . Thcy will use Zimpro@ wet-air oxidation with DuPont’s PACT powdered activated carbon. Carbon will be regenerated, and secondary sludge oxidized. Brown and Calclwell (Walnut Creek, C A I is preparing a resource recovery plan for the Puerto Rico Solid Waste Management Authority to cover the entire island---important, in this case, because PR is apparently running out of landfill space. Gould Inc. is providing motor controls for the sewage treatment plant at Wilton, ME, which will be partially powered by sofar energy and will handle 450 000 gpd.
IL’ Conkersion Systems, Inc. (Horsham, PA) has formed a subsidiary, Envirosafe Services, Inc., to provide safe. governmenl-approved disposal of industrial waste materials. Peabody Process Systems (Stamford, C T ) will supply a Holmes-Stretford desulfurization unit, for $2 million, to Northern California Power Agency‘s Geothermal Project at Geyserville,
C A . It will service I10 MW, and recover about 3 tpd of sulfur from vent gases.
dling 22 000 cfm at a salt mine processing plant after bags failed and wet collectors posed disposal problems.
Union Carbide Corp. says that its U N O X oxygen-activated sludge system is part of a recently completed $80-million sewer improvement project for the East Bay Municipal Utility District (CA). Treatment capacity is 300 million gpd (primary) and 168 million gpd (secondary).
FMC Corp. announced that its double alkali flue gas desulfurization process was selected for a planned coal gasification demonstration plant to make 24 million scf of pipeline gas and 2100 bbl/d of fuel and naphtha from 2300 tpd of Illinois coal.
Westinghouse Electric Corp. has listed the 575-MW Connecticut Yankee nuclear plant as an exemplary plant. I t is now 12 years old and produces electricity “at a lower cost than most other forms of energy.” Westinghouse provided the pressurized reactor.
The American Society for Testing and Materials has announced a new practice for describing environmental conditions relevant to spill control systems for use on water.
Envirotech/Hawley Industrial Exhaust Systems (Coraopolis, PA) will provide a coke-oven pushing emission control system to Chattanooga Coke and Chemical Co. to handle 100 000 cfm. Hydro Clear Corp. (Avon Lake, OH) will supply a multicelled filtering system to handle a peak flow of I29 mgd a t new wastewater treat men t (w w t ) facilities being built at Gary, IN. The system wJill use innovative backwash techniques to reduce energy use. Dames & Rloore (Los Angeles, CA) has been retained by Mobil Chemical Co., a Mobil Oil subsidiary. to do baseline surface .water studies for construction of a new phosphate mine south of Fort Meade, FL. KF’B, Inc. (Tustin, CA) a ResearchCottrell Energy Company. will supply 1 1 continuous flue-gas emission monitoring systems to the Los Angeles Dept. of Water and Power. Radian Corp. (Austin, T X ) has a $ I million contract to study secondary aerosol formation for the EPA. There is to be a 1 000-ft3 mobile flow reactor for simulation, as well as actual plume studies. Aerodyne Detelopment Corp. (Cleveland, O H ) says that its Type “ S V ” cyclone dust removers are easily han-
Combustion Equipment Associates w i I I design/supply/fabricate scrubbers and ductwork for lime-based venturi scrubbers to eliminate about 96% of SO? from coal to be burned by two 778-MW units at the Montana Colstrip Station. Research-Cottrell will design/con\truct a wood mechanical-draft cooling tower for Public Service of New Mexico, at a 50-MW geothermal unit. Biospherics Inc. (Rockville, MD) will operate the laboratory of the Blue PI ai n s Wastewater Treat ni e n t PI ant (Washington, DC), a 300-mgd facility. The contract is for $300 000/y. ERT (Concord, V A ) has devised a neu mathematical model which allows ;I power plant in Massachusetts to convert from oil to coal. Previously, such a change was not allowed in that state because of air “regs.“ Inco Metals Co. will commercially test a new process of nickel smelting at Port Colborne, Ontario, which will suppress SO? emissions by concentrating SO? as a feedstock for sulfuric acid manufacture . Baumco, Inc. (Pittsburgh, PA) has introduced the European Dumag Sludge Burner System that can burn many difficult materials and which works on a supersonic principle. Volume 14, Number 4 , April 1980
