A METHOD FOR RECYCLING ZINC PHOSPHATING PROCESS WASTE IS PROPOSED. ABOUT THREE MILLION POUNDS OF SOLID CHEMICAL WASTE IS GENERATED ANNUALLY FROM ZINC PHOSPHATING IN NORTH AMERICA. THE WASTE IS AN INORGANIC MIXED ZINC/IRON TERTIARY SALT OF PHOSPHORIC ACID. TOXICITY LEVELS VARY BUT MOST WASTES CONTAIN NICKEL, CHROME, LEAD, AND OTHER TOXINS IN SMALL QUANTITIES. THE METHOD DEPENDS UPON CONTINUOUS REMO ...

THE TECHNICAL OBJECTIVES OF THIS PROPOSAL ARE ORIENTED TOWARD THE DEVELOPMENT OF SOIL SURFACTANT FLUSHING AND WASHING AS A LOW-COST, LOW-IMPACT, LOW-RISK, EFFECTIVE TECHNIQUE FOR THE REMOVAL AND ULTIMATE DESTRUCTION OF THE ORGANIC CONTAMINANTS IN SOIL. THESE OBJECTIVES ARE: DEMONSTRATION OF THE EFFECTIVENESS OF AN IONIC SURFACTANT SOLUTION AT CONCENTRATIONS ABOVE THE CRITICAL MICELLE CONCENTRATION ...

N/A

A NEW METHOD OF APPLYING THIN, ELECTRICALLY CONDUCTIVE FILMSTO A SUBSTRATE AS A REPLACEMENT FOR CONTINUOUS STRIP ELECTROPLATING (CSEP) IS DESIRABLE FROM AN ENVIRONMENTAL STANDPOINT AS A MEANS OF LIMITING CHEMICAL AND METALLIC CONTAMINATION OF WASTEWATER AND THE ECONOMIC COSTS OF TREATMENT. AVCA CORPORATION HAS DONE PRELIMINARY DESIGN WORK ON A METHOD AND APPARATUS FOR GENERATING THIN FILMS BY LEVI ...

N/A

THE 1986 AMENDMENTS TO THE SAFE DRINKING WATER ACT REQUIRES 99.9% INACTIVATION OF GIARDIA WATER TREATMENT FACILITIES THAT UTILIZE SURFACE WATER WILL HAVE TO USE OZONE OR CHLORINE DIOXIDE TO BE COST EFFECTIVE IN MEETING THE NEW REGULATION. ]THE SPECIFIC AIMS OF THIS PROJECT ARE TO EVALUATE THE PROCEDURES FOR ELIMINATION OF CHLORITE ION AND CHLORATE ION BY-PRODUCTS WHEN CHLORINE DIOXIDE IS USED IN D ...

MOTOR OPERATED GATE VALVE OPERABILITY PROBLEMS AND FAILURES AT NUCLEAR POWER PLANTS ARE A MAJOR SAFETY CONCERN AS STATEDIN NRC IE BULLETIN 85-03 AND GENERIC LETTER 89-10. THIS PROPOSAL IS AIMED AT IMPROVING GATE VALVE PERFORMANCE BY (1) DEVELOPING COMPREHENSIVE PERFORMANCE PREDICTION MODELS FOR USE OVER A RANGE OF OPERATING CONDITIONS, (2) DEFINING LIMITS, BASED ON SPECIFIC DESIGNS, BEYOND WHICH E ...

THE AIR WE BREATHE IS POLLUTED MAINLY BY THE FACTORIES AND VEHICLES THAT ARE AN INTEGRAL PART OF MODERN TECHNOLOGICAL SOCIETY. THE CONTINUED RESEARCH FOR BETTER CONTROL OF THE FACTORS THAT EFFECT ENVIRONMENTAL QUALITY AND PUBLIC SAFETY,MUST BE INTENSIFIED. BEHNKEN AND ASSOCIATES, INC. PERSONNELHAVE DISCOVERED A CONCEPT THAT OFFERS A SIGNIFICANT CONTRIBUTION TOWARD ELIMINATING AIR POLLUTION FROM TH ...

THE MTIC INDIRECT STEAM REFORMING PROCESS OFFERS A COST EFFECTIVE ALTERNATIVE TO THE EXISTING WASTE-TO-ENERGY INCINERATION OF MUNICIPAL SLUDGE WASTE (MSW) OR REFUSE- DERIVED FUEL (RDF). THE PROCESS HAS THE POTENTIAL FOR RESOLVING MANY OF THE ENVIRONMENTAL ISSUES ASSOCIATED WITH INCINERATION, ESPECIALLY IN THE CONTROL OF CHLORINATED DIOXINS AND FURANS AS WELL AS EMISSIONS OF TOXIC METALS; PARTICULA ...

THE PHASE I RESEARCH WILL COMPLETE DEVELOPMENT OF A MATHEMATICAL MODEL AND CONDUCT CONTINUOUS FLOW BENCH-SCALE STUDIES TO EVALUATE THE FEASIBILITY AND APPLICABILITY OF A PROPOSED ALTERNATIVE OFFGAS VOC CONTROL STRATEGY. THE PROPOSED SYSTEM UTILIZED OFFGAS CAPTURE FROM WASTEWATER TREATMENT AND STORAGE UNITS FOR RECYCLE TO AN AEROBIC BIOLOGICAL TREATMENT PROCESS. THE RECYCLED GAS PHASE WILL INCREASE ...
