One of the program areas of interest to the U.S. Environmental Protection Agency (EPA) is the development of rapid, non-invasive monitors to detect exposure to toxic air pollutants at trace (ppt) levels. Of the 356 chemicals listed on the Chemical Emergency Preparedness and Prevention Office¿s List of Extremely Hazardous Substances (Section 302 of the Emergency Planning and Community Right-To-Kn ...

SAFE, COST EFFECTIVE ALTERNATIVES TO CHLORINE TREATMENT OF DRINKING WATER FOR DISTRIBUTION AND DISINFECTION HAVE BEEN SOUGHT FOR SOME TIME. CHLORINE DIOXIDE IS A VIABLE ALTERNATIVE TO CHLORINE FOR THE TREATMENT OF EVEN POOR QUALITY WATER SUPPLIES AND THE REDUCTION OF POTENTIAL CANCER CAUSING CHLORINATED ORGANICS. ITS WIDESPREAD USE HAS BEEN INHIBITED BY THE COSTS AND/OR COMPLEXITY OF ITS PRODUCTIO ...

THERE ARE NUMEROUS INDUSTRIAL PROCESSES REQUIRING THAT MATERIAL BE HEATED AND THEN SUBSEQUENTLY COOLED. IF MOST OF THIS HEAT IS RECOVERED AND RECYCLED TO THE OVEN, THE NET POWER INPUT TO THE OVEN COULD BE SUBSTANTIALLY REDUCED. THE KEY TO ACCOMPLISHING THIS IS AN INCREASE OF THE HEAT TRANSFER COEFFICIENT BETWEEN GAS AND MATERIAL SO THAT THE HEAT EXCHANGERS ARE RESASONABLY COMPACT. SIMPLE EXPERIMEN ...

Engineering Mechanics Corporation of Columbus¿ (Emc2) approach is to convert both municipal and industrial solid waste products into large dimensional composite timbers for structural and waterfront applications through a novel and efficient manufacturing process. The environmental benefits include: (1) diversion of solid waste plastics and reinforcements from landfills; (2) pollution prevention ...

HydroPure Technologies, working with Battelle Pacific Northwest Division, is proposing to determine the commercial feasibility of the high-capacity selective sorbent, self-assembled monolayers on mesoporous supports (SAMMS) as an effective and commercially viable process. This sorbent has the potential advantage of fully treating arsenic (As) in drinking waters to the new Drinking Water Standard. ...

THE U.S. POSSESSES HUGE COAL RESERVES, BUT SULFUR DIOXIDE (SO2) RELEASED UPON COMBUSTION IS A MAJOR CONTRIBUTOR TO ACID RAIN. SIGNIFICANT ADVANCES HAVE BEEN MADE IN THE DEVELOPMENT OF MICROBIAL PROCESSES FOR PRECOMBUSTION REMOVALOF INORGANIC SULFUR FROM COAL. THIOBACILLUS AND SULFOLOBUS SP. HAVE BEEN MOST FREQUENTLY EMPLOYED. THEY ARE OPTIMALLY ADAPTED TO FUNCTION AT A PH BELOW 3 AND OFTEN AT ELEV ...

OVER THE LAST SEVERAL YEARS, THE EPA HAS DEVOTED MAJOR EF- FORTS TO IDENTIFY AND DOCUMENT THE MAGNITUDE OF THE RISKS OFENVIRONMENTAL POLLUTION DUE TO LEAKING UDERGROUND STORAGE TANKS (UST). IN APRIL 1987, THE EPA PUBLISHED THE PROPOSED REGULATIONS FOR THE OWNERS AND OPERATORS OF UST, WHICH ARE EXPECTED TO BE FINALIZEDD IN EARLY 1988. THESE REGULATIONS INCLUDE REQUIREMENTS FOR TANK TIGHTNESS TESTS, ...

Heavy-duty highway diesel engine NOx emission standards will drop from the current 4.0 g/bhp-hr level to 0.2 g/bhp-hr in 2007. No technology, or combination of technologies, has yet demonstrated the ability to achieve such a NOx reduction on the road. During the last year, Sorbent Technologies Corporation has been working on a Phase II research project to develop a new NOx control concept for st ...
