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 ...

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 ...

Phase I research proved the feasibility of EnerTech's Slurry Carbonization technology for economically producing clean and marketable fuels from high-moisture agricultural residues and wastes, especially animal manures. The Slury Carbonization technology effectively transformed low-grade animal residues, through a moderate temperature and pressure carbonization process, into a uniform and especial ...

Studies have found Cryptosporidium parvum (C. parvum) oocysts in 65-97% of surface water tested inthe United States. The current Surface Water Treatment Rule does not include analysis for C. parvum.However, the increased incidence of outbreaks involving Cryptosporidiosis have instigated aninvestigation into whether or not testing should be included in the Enhanced Surface Water TreatmentRule. Th ...

THE SPECIFIC OBJECTIVE OF THIS STUDY IS TO EVALUATE THE TECHNICAL FEASIBILITY OF EMPLOYING A FIXED FILM ANAEROBIC DIGESTER SYSTEM TO ACHIEVE AN ADEQUATE DEGREE OF BIOLOGICAL SLUDGE DIGESTION WITH A RETENTION TIME WHICH IS ONE ORDER OFMAGNITUDE SHORTER THAN THAT OF THE CONVENTIONAL SUSPENDED- GROWTH DIGESTER. IN ORDER TO MAXIMIZE THE BIOLOGICAL REACTION RATE, THE INFLUENT SLUDGE WILL BE TREATED WIT ...

Escherichia coli causes a number of serious poultry diseases, including colibacillosis resulting inmillions of dollars lost to the poultry industry each year. Contamination of poultry products bySalmonella is a major public health concern. Development of a bivalent poultry vaccine directedagainst both of these bacteria would benefit the public health and increase poultry production. Orallyadmin ...

THE PROPOSED FEASIBILITY RESEARCH IS TO USE A UNIQUE GRAFTI ING TECHNIQUE TO MODIFY MEMBRANE MATERIALS IN SUCH A WAY AS TO RENDER THEM USEFUL FOR SPECIFIC WATER TREATMENT SITUATIONS. THE WORK WILL SPECIFICALLY FOCUS ON THE DEVELOP MENT OF THE GRAFTING TECHNIQUE FOR POROUS MEMBRANE MATERIAL S. THE TECHNIQUE WILL BE DEMONSTRATED BY THE GRAFTING OF CHARGED MONOMER AND POLYMERS ONTO SEVERAL MATERIALS ...
