THE DESTRUCTION OF ORGANIC HAZARDOUS WASTE BY ELECTRIC ARC PYROLYSIS HAS BEEN DEMONSTRATED TO BE TECHNICALLY FEASIBLE BY OTHERS. THE PRINCIPAL PROBLEMS LIE IN (1) THE SHORT LIFEOF THE ELECTRODES (AND RELATED STRUCTURES) DUE TO THE HIGH TEMPERATURES INVOLVED, AND (2) THE RELATIVELY HIGH COST OF THE ELECTRIC POWER NEEDED. APPLIED RESEARCH ASSOCIATES, INC. PROPOSE TO DESTROY ORGANIC HAZARDOUS WASTE B ...

RINSE WATER AND OTHER AQUEOUS WASTES FROM METAL FINISHING OPERATIONS PRESENT A DISPOSAL PROBLEM BECAUSE OF THEIR HEAVY METAL AND AGGRESSIVE CHEMICAL CONTENT. GENERALLY, THESE WASTES ARE TREATED CHEMICALLY TO PRECIPITATE THE METALIONS AS OXIDES OR HYDROXIDES. THIS TREATMENT IS COSTLY BECAUSE IT INVOLVES THE ADDITION OF CHEMICALS, DISPOSAL OF SLUDGE WITH LOSS OF VALUABLE METALS, AND LOSS OF THE HIGH ...

ORGANIC BIODEGRADABLE FILLERS ARE MANUFACTURED TO OPTIMIZE PARTICLE SHAPE FOR REINFORCEMENT VALUE IN POLYETHYLENE. FILLER IS ALSO "SURFACE MODIFIED" TO ENHANCE COMPATIBILITY AND BOND STRENGTH AT THE FILLER-POLYMER INTERFACE. THREE DIFFERENT PARTICLE SIZE FILLERS ARE USED IN POLYMER SUBSTITUTION RATES OF 10, 20, 30, AND 40% DURING COMPOUNDING. OPTIMUM COMPOUNDING AND MOLDING CONDITIONS AREDETERMINE ...

SOIL WASHING OR FLUSHING HAS BEEN SHOWN TO BE AN EFFECTIVE METHOD FOR REMOVING HEAVY METALS FROM METAL-CONTAMINATED SOILS AT SUPERFUND SITES. SANDY SOILS CAN OFTEN BE WASHED WITH WATER TO MOBILIZE METAL IONS IN AN AQUEOUS PHASE, BUT FOR CLAY SOILS OR SOILS WHICH CONTAIN INSOLUBLE METAL COMPOUNDS, E.G., LEAD SULFATE, OTHER ADDITIVES SUCH AS CHELATING AGENTS (EDTA) ARE USED TO EFFECT TRANSFER OF MET ...

MRC PROPOSES TO DEVELOP A SAFETY PERFORMANCE INDICATOR (PI) OF THE ELECTROMAGNETIC (EM) PROTECTION STATUS OF A NUCLEAR POWER PLANT (NPP). WE BELIEVE THAT SUCH A PI IS NEEDED BECAUSE: (1) EM ENVIRONMENTAL POLLUTION IS ON THE INCREASE,(2) ADDITIONAL EM THREATS MUST BE EVALUATED, AND (3) DISRUPTION OF NPP OPERATIONS BY EM EFFECTS CAN AND MUST BE AVOIDED. PREVIOUS STUDIES HAVE ADDRESSED THE ISSUE OF E ...

THE UNCERTAINTY IN MEASURING NEUTRON DOSE EQUIVALENT RATES RESULTS IN UNCERTAINTY IN ASSIGNMENT OF THE PROPER DOSE TO OCCUPATIONAL RECORDS AND CAN RESULT IN IMPROPER IMPLEMENTATION OF CONTROLS TO LIMIT THE EXPOSURE. A NOVEL PORTABLE NEUTRON SPECTROMETER IS PROPOSED WHICH WILL REDUCE THE UNCERTAINTY OF SUCH MEASUREMENTS TO LESS THAN 20%. MANYCOMPONENTS OF THIS DEVICE ARE COMMERCIALLY AVAILABLE. SYS ...

N/A

CURRENT METAL CUTTING AND FINISHING OPERATIONS USE SKIMMING AND FILTRATION TO TRY TO SEPARATE WASTES FROM THEIR WATER BASED CUTTING FLUIDS. THE RESIDUAL LIQUID FROM THE FILTRATION CONSISTS OF ULTRAFINE METAL PARTICLES CONTAINING HAZARDOUS HEAVY METALS LIKE LEAD, ZINC, AND CADMIUM AND A TIGHTLY EMULSIFIED OIL-IN-WATER PHASE. THIS SLUDGE IS NOT AMENABLE TO FURTHER TREATMENT AND MUST BE HAULED OFF AS ...
