Drinking water filtration plants nationwide are failing to adequately reduce the public health risk due to exposure to sometimes lethal Cryptosporidium and other microbial particle levels. New regulations also will require reduction of dissolved organic carbon (DOC) to minimize the risk from potentially carcinogenic reaction by-products resulting from disinfection. Particle and DBP precursors ar ...

Q-DOT proposes to develop a unizue, lower-power, low-cost beamformer for portable imaging sonars. The original two chip set will form 100 beams from 100 input channels. A 0.3 cm2 BiCMOS chip comprises a low noise amplifier (LNA), a time-gain control (TGC), an apodizer and a Delta-Signma modulation (ADC) for each channel. A 0.66 cm2 CMOS chip accepts 100 digital input channels and produces 100 d ...

The U.S. demand for chlorinated hydrocarbons exceeds 15 million tons annually. The production of these chemicals requires chlorine (Cl2) and produces HCl as an unavoidable by-product. Stringent environmental regulations limit the shipment of hazardous wastes like HCl, and the disposal of HCl by neutralization is costly. A consortium of 15 companies is developing an in-process recycling system t ...

Scientific Fishery Systems, Inc. (SciFish) recently completed a Phase I SBIR that used neural networks to learn the relationship between temperature and the spectra of broadband returns for a fixed location during a fixed time of the year. This approach relaxes the assumption of the consistency of backscatterers: now we will assume that the backscatter will be consistent at the same location at ...

THE MAJOR OBJECTIVE OF THE RESEARCH PROPOSED IS EVALUATION OF THE TECHNICAL FEASIBILITY OF THE NEW DESIGN FEATURES OF THE FILTER AND A COMPARISON OF ITS PERFORMANCE WITH CONVEN- TIONAL FILTERS IN TREATMENT OF WASTEWATERS. THE MAJOR SPECIFIC FEATURE OF THE FILTER IS A STONE-GRANULAR MEDIA BED WHICH IS EXPECTED TO PROVIDE A NON CLOGGING OPERATION, LONGER FILTRATION RUNS AND GREATER DIRT CAPACITY THA ...

ELECTRIC ARC FURNACE DUST IS LISTED AS A HAZARDOUS WASTE. TOTAL PRODUCTION OF THIS DUST IS ESTIMATED TO BE 500,000 TONS AT SOME 77 LOCATION RANGING IN SCALE FORM LESS THAN 1,000 TONS TO OVER 20,000 TONS PER YEAR. A PROCESS IS PROPOSED WHICH MAY PERMIT ON-SITE, SIMPLE RECOVERY OF CONTAMINANT METALS IN THE DUST. THE PROCESS RECYCLES RECYCLES CHEMICAL REAGENTS AND AQUEOUS LEACH , MINIMIZIN COST AND A ...

THE DEVELOPMENT OF NEW SELECTIVE DETECTORS FOR GAS AND LIQUID CHROMTOGRAPHY FOR THE SENSITIVE MEASUREMENT OF SULFUR-CONTAINING COMPOUNDS IS PROPOSED. THESE DETECTORS ARE BASEDON FLUORINE-INDUCED CHEMILUMINESCENCE AND ARE HIGHLY SE SELECTIVE FOR SULFIDES, DISULFIDES AND MERCAPTANS. THE MAJORRESEARCH PROPOSED IS THE DEVELOPMENT OF NEW SOURCES OF FLU FLUORINE WHICH WILL BE SAFE, PROTABLE, AND LOW IN ...
