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 ...

WASTE PICKLING LIQUOR IS PRODUCED WHIN ACID IS USED TO RE- MOVED SCALE FROM STEEL PRODUCTS. TYPICALLY IT CONTAINS 10% ACID AND 5% IRON IN THE FORM OF THE FERROUS SALT OF THE ACIDUSED. IT IS PRODUCED IN LARGE QUANTITIES. ITS DISPOSAL IS DIFFICULT AND WILL BECOME MORE SO WHEN THE PLANNED TOTAL BANON ON DEPOSITION OF LIQUIDS IN A LAND DISPOSAL SITES BECOMES EFFECTIVE. AN ELECTROLYTIC PROCESS WILL BE ...

THE CONTAINMENT OF TOXIC MATERIALS ALREADY BURIED IN THE GROUND AND THE CONSTRUCTION OF NEW DISPOSAL SITES ARE DIFFI-CULT TASKS. IN BOTH CASES THERE IS A NEED FOR VERTICAL AND HORIZONTAL BARRIER WALLS IN THE GROUND THAT ARE KNOWN TO BE DIFFICULT AND EXPENSIVE TO CONSTRUCT WITH CURRENTLY-AVAILA- BLE TECHNOLOGIES. FLUIDYNE PROPOSES TO CONSTRUCT SUCH BARRIER WALLS WITH A NOVEL ONE-STEP PROCESS THT IN ...

AN ATTRACTIVE POTENTIAL ALTERNATIVE TO CURRENT HAZARDOUS ORGANICS INCINERATORS IS THE CATALYTICALLY STABILIZED THER- MAL (CST) COMBUSTOR. EXPLORED IN THE LATE 1970'S (WITH EPA FUNDING) AS A COMBUSTION SYSTEM TO ELIMINATE GAS TURBINE NOXEMISSIONS, THE CST COMBUSTOR USES CATALYTIC SURFACE REAC- TIONS TO STABILIZE GAS PHASE COMBUSTION, COMBINING HIGH GAS PHASE REACTION RATES WITH THE LEAN BURN CAPABI ...

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 ...

RECENT PROMISING DEVELOPMENTS IN THE PETROLEUM INDUSTRY "PROFILE MODIFICATION TECHNOLOGY" (PMT) WILL BE EVALUATED FOR THEIR APPLICATION TO LEAKING LANDFILL SITES. PROFILE FLOW MODIFICATION TREATMENTS ARE USED TO INCREASE FLOW RESISTANCE IN HIGH PERMEABILITY AREAS FAR (75 FEET TO AS MUCH AS 1000 FEET) FROM THE INJECTION WELLBORE. THESE TREATMENTS CAN WITHSTAND FORMATION PRESSURES AND TEMPERATURES U ...

USE OF PULSED ULTRAVIOLET RADIATION IS PROPOSED AS A MEANS TTO DETOXIFY EQUIPMENT USED IN THE PREPARATION OF TOXIC CH CHEMICAL COMPOUNDS. THE RADIATION WILL SERVE TO BOTH V VAPORIZE MATERIAL ADHERING TO THE SURFACE AS WELL AS TO BRING ABOUT PHOTOLYTIC DESTRUCTION. THIS COMBINATION OF EFFEFFECT IS PROJECTED TO PROVIDE A DRY CLEANING CONCEPT WHERE THE TOXIC MATERIAL AND ITS BYPRODUCTS (POTENTIALLY T ...

STUDIES INDICATE THAT STRAIGHT SEPTAGE INTRODUCTION TO ACT IVATED SLUDGE PLANTS CAUSES SHOCK LOADING AND SUBSEQUENT VIOLATION OF EFFLUENT PERMIT STANDARDS. THIS PROJECT INTENDS TO EVALUATE DEWATERING OF SLUDGE BY THEUSE OF WIRE CLOTH SCREENING TO DETERMINE IF THE DEWATERED SLUDGE MEETS LANDFILL ACCEPTABILITY STANDARDS. IT INTENDS A ALSO TO DETERMINE IF THE RETURN OF THE FILTRATE TO THE S SEPTIC TA ...
