Lead in household paint and dust is a serious health hazard, as low-level lead exposure can result in a number of adverse health effects, especially in children. Onsite and real-time detection and quantification of lead in paint/dust are very important to homeowners and certified lead-based paint removal professionals. Toward this end, both field-portable equipment (such as X-ray fluorescenc ...

Various oily wastes are generated when performing vehicle maintenance operations, including used oil drained from the engine, the oil filter, and even oil absorbent used to clean up oil that has spilled on the floor. At one time these wastes were placed in landfills. Concerns with oil from these wastes migrating into surface and groundwater has prompted a number of state and federal ...

Perchlorate is a widely used component of solid fuel, missile and rocket propellants, explosives, and pyrotechnics. It has been shown to reduce iodide uptake into the thyroid gland. The U.S. Environmental Protection Agency (EPA) has found perchlorate contamination in 18 states and believes contamination may exist in as many as 39 states. In early January 2005, the National Academy of Science ...

BIOLOGICAL AND HAZARDOUS SLUDGES AND SLURRIES REPRESENT A MAJOR DISPOSAL PROBLEM. DEWATERING IS A MAJOR COST ELEMENT. THIS TWO-STEP TECHNOLOGY INVOLVES A FIRST STEP ACHIEVING ESSENTIALLY COMPLETE DEWATERING IN A BACKMIX REACTOR BY DISPERSION OF SLUDGE IN HEAVY OIL REACTION MEDIA MAINTAINED AT WATER VAPORIZATION TEMPERATURE USING ENERGY EFFICIENT VAPOR RECOMPRESSION. THE OXIDIZABLE IN THE VAPOR PHA ...

SLUDGE WASTE CONTAINING CR(VI) FROM CHROMIUM PLATING OPERATIONS IS CLASSIFIED AS HAZARDOUS AND ITS DISPOSAL IS A MAJOR CONCERN. IT CAN BE RECOVERED FOR FUTURE METAL USE IN REMELTING OPERATIONS, CAN BE STORED, OR CAN BE DISPOSED AFTER MODIFICATION TO A LEGALLY ACCEPTABLE FORM. IN PHASE I, THE CONVERSION OF SLUDGE WASTE FROM CHROMIUM PLATING OPERATIONS INTO FERROCHROMIUM ALLOYS IS PROPOSED. BY MEANS ...

A HIGH EFFICIENCY ACTIVATED CARBON GRANULE WILL BE DEVELOPED FOR DRINKING WATER TREATMENT. THE FOUNDATION FOR THIS HIGH EFFICIENCY GRANULE IS A SUPERACTIVATED CARBON WITH A BET SURFACE AREA IN EXCESS OF 3000 M(2)/GM USING THE STANDARD PROCEDURE BY BRUNAUER, EMMETT, AND TELLER, AND AN IODINE NUMBER GREATER THAN 3000 MG/G. TWO GRANULATIN TECHNOLOGIES WILL BE EXPLORED: SPHERICAL AGGLOMERATION AND EXT ...

CONVENTIONAL RECYCLING OF WASTE PLASTICS IS LIMITED BY INEFFICIENT TECHNOLOGY AND NUMEROUS ECONOMIC BARRIERS. AS AN ALTERNATIVE, DIRECT PROCESSING OF RAW WASTE PLASTICS INTO FINISHED PRODUCTS HAS SHOWN PROMISE, BUT ITS FULL POTENTIAL REMAINS UNKNOWN. USING STATISTICALLY DESIGNED EXPERIMENTS, ROBERT MORGAN & COMPANY, INC. HAS SUCCESSFULLY PROCESSED BLENDS OF RAW WASTE PLASTICS INTO USEFUL COMPOSITE ...
