Emissions of volatile organic compounds (VOCs) and hazardous air polutants (HAPS are a serioud environmental issue. These pollutants are requlated to protect human health and encourage the development of better control technologies. Current technologies to control thses emissions, until better materials are developed, include destructive and/or recovery-based technologies. Implementation of ads ...

Caviton has developed a novel technique for the continuous monitoring of trace metals emissions. This technique is based on a microdischarge light, which is collected by a spectrometer and analyzed. All metals tested to date can b detected and the focus of this Phase II project is to develop a sampling system, carry out laboratory tests, then move to field tests of sampling and analysis. Finall ...

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 ...

This SBIR proposal addresses worker and environmental safety concerns regarding the use of toxic cutting fluids in metal shaping operations. The toxicity of cutting fluids cn be caused by either the constituents fo the cutting fluid chemistyr or in the case of water-soluble emulsions, the toxicity can be caused by biocides intended to control baterial growth. This proposal seeks to adapt an adve ...

This Small Business Innovations Research Phase I project is designed to determine the feasibility of preparing an environmentally friendly isocyanate-free solvent-free hybrid resin system ssuitable fo industrial applications such as automobile refinishing and floor coatings. In particular, the overall objective of this program is to determine the most approptiate ratios or reactive groups of UV c ...

Lead is a soft, low melting point, high density, and inexpensivve material that can be easily shaped. All these attributes have made lead useful in appplications such as bullets, fishing rod sinkers, weights for balancing tires, hunting shots, etc. In spite of all these attractive properties, lead is a major environmental contaminant due to its toxicity. Leaed is toxic and cna be stored in biol ...

nGimat proposes an advancement of the versatile integrated optic chip sensor for detection/identificaton of waterborne bacterial and viral pathogens, and toxins. nGimat will utilize magnetic nanoparticles to enable an advanced signal processing scheme that promises the enhanced optical biosensor detection sensitivity (sub-ppb). The fabrication of the necessary magnetic nanoprticles will be facil ...

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, ...

Cupric chloride and ammoniacla etchants are used to remove unwanted copper form printed circuit boards. They are used in a continuous"bleed and feed" mode, which leads to the formation of a hazardous copper containing waste. This waste material must be hauled form the site for disposal. In addition, cupric hcloride etchant requires the use of hazardous oxidants such as chlorine gas or sodium ch ...
