OVER 25 BILLION GALLONS OF WASTE WATER ARE PRODUCED EACH YEAR AS BY-PRODUCTS OF CIRCUIT BOARD PRODUCTION. WASTES, INCLUDING COPPER, LEAD, NICKEL, CHROMIUM, DISSOLVED ORGANICSACIDS, CAUSTICS AND CHLORINATED SOLVENTS MUST BE TREATED ANDDISPOSED OF OR RECYCLED. COMPLIANCE WITH ANTI-POLLUTION REGULATIONS HAS BECOME EXTREMELY COSTLY AND INCREASINGLY COMPLEX. A TECHNIQUE IS PROPOSED IN THIS PROJECT FOR ...

ABOUT 28 MILLION POUNDS OF SPENT HYDROTREATING CATALYST CONTAINING $23,000,000 IN RECOVERABLE CHEMICALS WAS DIS POSED OF IN THE UNITED STATES DURING 1985. ONLY 20% OF THE SPENT CATALYST UNDERWENT SOME FORM OF RECLAMATION PROCESS- ING. THE AMOUNT OF SPENT HYDROTREATING CATALYST REQUIRING DISPOSAL IS EXPECTED TO DOUBLE BY 1994 WITH THE EX DISPOSAL IS EXPECTED TO DOUBLE BY 1994 WITH THE HYDRODESUL- F ...

THE COST FOR REMOVING TOXIC CHEMICALS FROM THE SOIL WITH PRESENT TECHNOLOGY IS ENORMOUS, IN SOME CASES, POPULATIONS THE COST FOR REMOVING TOXIC CHEMICALS FROM THE SOIL WITH PRESENT TECHNOLOGY IS ENORMOUS. IN SOME CASES, POPULATIONS MUST BE RELOCATED AND MANY ACRE-FEET OF SOIL MUST BE EXCAVA-TED AND TREATED OR STORED IN "SAFE" STORAGE FACILITIES. IM-PROVED TECHNOLOGY IS NEEDED TO REDUCE CLEAN-UP CO ...

IN THIS RESEARCH, AN ELECTRON BEAM PROCESS WILL BE INVESTI- GATED WHICH HAS THE POTENTIAL TO DESTROY TOXIC MOLECULES SUCH AS DIOXINS, FURANS, AND POLYNUCLEAR AROMATIC HYDROCAR- CARBONS PRODUCED, FOR EXAMPLE, BY THE INCINERATION OF MUNICIPAL SOLID WASTE. SOME ISOMERS OF THESE COMPOUNDS ARE HIGHLY TOXIC; THEREFORE,THE WORK WILL BE ACCOMPLISHED USING NON-TOXIC MODEL COMPOUNDS EXHIBITING CHEMICAL FUNC ...

NEW FEDERAL STANDARDS THAT COME INTO EFFECT IN 1988 WILL REQUIRE HEAVY DUTY DIESEL EXHAUST PARTICULATE EMISSION REDUCTIONS OF APPROXIMATELY 60%. IT HAS BEEN SHOWN THAT APPROXIMATELY 75% OF DIESEL PARTICLES ARE CHANGED DURING COMBUSTION AND COULD BE COLLECTED ON THE SURFACES OF AN ELECTROSTATIC AGGLOMERATOR (ESA). THESE PARTICLES WOULD GROW ON THE SURFACES BY AGGLOMERATION AND BE REENTRAINED INTO T ...

THE USE OF SOLAR AND/OR ARTIFICIALLY IRRADIATED SEMICONDUCTOR POWDERS TO PHOTOCATALYTICALLY MINERALIZE 12-400 PPM TRICHLOROETHYLENE (TCE) CONTAMINATED WATER OBTAINED FROM A CANDIDATE SUPERFUND SITE IS PROPOSED. THESESEMICONDUCTOR POWDERS ARE INEXPENSIVE, NONTOXIC, RECYCABLE AND HAVE BEEN SUCCESSFULLY EMPLOYED TO MINERALIZE TCE, PENTACHLOROPHENOL AND MANY OTHER HALOGENATED HYDROCARBONS RAPIDLY. THE ...

IN PHASE I, RESEARCH WILL BE CONDUCTED TO DEVELOP AN AP- PROACH FOR A NEW COST-EFFECTIVE TECHNOLOGY TO MINERALIZE A WIDE VARIETY OF TOXIC ORGANIC COMPOUNDS WHICH OCCUR IN LARGEAMOUNTS IN SOLID AND LIQUID INDUSTRIAL WATES. THIS APPROACH EMPLOYS PHOTOPROMOTED SOLID-CATALYZED OXIDATIVE DEGRADATION TO CONVERT THE TOXIC COMPOUNDS TO EN- VIRONMENTALLY COMPATIBLE PRODUCTS, NAMELY, CO2 FROM CHEMICALLY BOU ...
