Suspended ceiling tiles are widely used in commercial and residential construction because they offer flexibility and easy access to utilities. Most of the available tiles absorb water, resulting in sagging, staining, and mold/mildew growth. They also contain potentially hazardous chemicals and release airborne fibers when broken or cut. Existing tiles are not durable, requiring frequent replaceme ...

Small drinking water systems consistently provide safe, reliable drinking water to their customers; however challenges of such systems include; lack of financial resources, aging infrastructure, lack of scale, and technical/logistical challenges associated with regulation compliance. The deployment ofnew cost-effective monitoring technologies hold opportunities to substantially advance infrastruct ...

Polyurethanes are now made by reacting two components, one of which has toxic isocyanate groups. Isocyanates are especially hazardous to workers that spray-apply polyurethane paints. Researchers have developed less hazardous ways to make polyurethane, but they have poor performance, cure too slowly or are too expensive. In this project, TDA Research, Inc. (TDA) will develop new non-isocyanate two- ...

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 ...

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 ...

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 ...
