Chlorinated hydrocarbons represent the most prevalent contaminants of groundwater in the country. When released in the subsurface, they tend to persist below the water table, and it can take decades or centuries before slow-moving groundwater completely dissolves accumulations of chlorinated solvent product. Analytical methods currently available for monitoring these compounds require extensive ...

Heavy metal species mobilized and released into the environment by technological activities tend to persist indefinitely, circulating and eventually accumulating throughout the food chain, posing a serious threat to the environment, animals, and humans. Typical industrial metal-containing discharges can be considered as point-source emissions, which in turn offer the possibility of feasible remed ...

The photographic industry consumes about 70 million troy ounces of silver annually. The technology used to recover the silver from concentrated solution is more than 40 years old. However, investigators project that, based on industry experience, as much as 20% of this silver is lost in the wash water and goes unrecovered. The toxicity of silver in the effluent is a growing concern in the United ...

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 ...

THE CLEAN AIR ACT REQUIRES THAT CERTAIN EXHAUST EMISSIONS STANDARDS BE MET BY HEAVY DUTY TRUCKS AND BUSSES (CLASS 8 VEHICLES) POWERED BY DIESEL ENGINES. THE LIMITS SET FOR 1998 CAN ONLY BE MET THRU THE USE OF EXHAUST TREATMENT DEVICES. A NOVEL WOVEN CERAMIC YARN FILTER CAPABLE OF HIGH TEMPERATURE OPERATION HAS BEEN DEVISED WHICH HAS THE POTENTIAL FOR IMPROVED DURABILITY AND FILTRATION PERFORMANCE ...

MORE COST EFFECTIVE SYSTEMS ARE NEEDED FOR RECOVERING VOLATILE ORGANIC CONTAMINANTS (VOCS) FROM INDUSTRIAL EXHAUSTGAS. THE PROPOSED APPROACH IS TO COOL THE GAS WELL BELOW THE DEW POINT OF THE VOCS. NORMALLY, ICE AND DIRT FORM ON THE CONDENSING SURFACE, REDUCING THE HEAT TRANSFER RATE, REQUIRING SHUT-DOWN AND PREVENTIVE MAINTENANCE. ENERGY INNOVATION, INC.'S, INNOVATION WILL ELIMINATE THESE REQUIRE ...
