The U.S. poultry industry produces more than 45 billion pounds of poultry annually. A majority of this production is from concentrated animal feeding operations. In a modern poultry growing facility, small chicks are raised in several large houses that typically cover over 20,000 ft2. Starting with each grow-out period, fresh wood mulch bedding material is spread over the house floor. Over the co ...

In a modern poultry growing facility, small chicks are raised in several large “houses” that typically cover over 20,000 ft2. Starting with each grow-out period, fresh wood mulch bedding material is spread over the house floor. Ove ...

CeraTech, Inc., proposes the development of novel (patent pending) phosphate-based concrete for fresh water and wastewater pipeline. The materials being investigated utilize a very high percentage of residual materials (coal ash, municipal solid waste ash, bio-solids ash, etc., up to 80 wt%). The concrete exhibits zero shrinkage as well as extremely high bondability to both concrete and reinforc ...

THE CONTRACTOR SHALL DEVELOP A FUZZY SET METHODOLOGY FOR UNCERTAINTY ANALYSIS IN PROBABILISTIC SEISMIC SAFETY ASSESSMENT OF NUCLEAR POWER PLANTS. FUZZY SET LOGIC WILL BEUSED FOR COLLECTING, QUANTIFYING AND PROPAGATING SUBJECTIVE,ENGINEERING JUDGEMENT USED IN THE UNCERTAINTY ANALYSIS. IN PHASE I, FEASIBILITY OF THE PROPOSED APPROACH WILL BE DEMONSTRATED BY APPLYING IT TO SELECTED PARTS OF A PROBABI ...

THE DISPOSAL OF MUNICIPAL SOLID WASTE (MSW) IS A COSTLY PROBLEM FOR ALL MUNICIPALITIES. THE U.S. ENVIRONMENTAL PROTECTION AGENCY HAS RECOMMENDED THAT SOURCE REDUCTION, RECYCLING, VOLUME REDUCTION, AND LANDFILLING BE APPLIED, IN THAT ORDER, IN THE TREATMENT OF MSW. RECYCLING HAS RECENTLY BECOME A MAJOR COMPONENT OF MUNICIPAL WASTE MANAGEMENT PROGRAMS. HIGH COSTS OF LABOR INTENSIVE CURBSIDE RECYCLIN ...

A low-impact delivery system for in-situ treatment if contaminated sediment is proposed. Unlike most conventional delivery systems that rely on injection or mechanical mixing of sediment, the proposed approach make use of natural mixing (bioturbation) processes to work treatment materials into the biologically-active zone. To accomplish this, agglomerates will be developed with the following pro ...

Diesel engines are widely used due to their high fuel efficiency. However, conventional diesel engines have high NOx and soot emissions. Selective catalytic reduction (SCR) for NOx reduction is less accepted by the construction industry due to complexity and cost. In-cylinder NOx reduction is more desirable. When low temperature combustion and/or premixed charge compression ignition (PCCI) combus ...

OZONE IS A VALUABLE ALTERNATE TO CHLORINE FOR THE DISINFECTION OF WASTEWATER AND WATER. IT GENERATES NO CHLORINATED ORGANICS AND LEAVES NO RESIDUALS HARMFUL TO HUMAN HEALTH OR TOXIC TO MARINE LIFE. THE OZONE REACTS THROUGH FREE RADICAL OR POLAR MECHANISMS UNDER WATER TREATMENT CONDITIONS DEPENDING ON PH AND OTHER FACTORS. THE MECHANISM OF BACTERIAL DISINFECTION IS NOT COMPLETELY UNDERSTOOD. THE OZ ...

A MODIFICATION OF THE ACTIVATED SLUDGE PROCESS HAS BEEN DEVELOPED TO ELIMINATE SLUDGE BULKING, MINIMIZE REACTOR VOLUMES, AND ENHANCE NUTRIENT REMOVALS. THE FLOW SHEET UTILIZES TWO SEGMENTS IN SERIES. THE FIRST EMPLOYS A 10 MINUTE MIXED LIQUOR CONTACTOR TO ADSORB 50-60% OF THE SOLUBLE CARBON SUBSTRATE. CONTACTOR MIXED LIQUOR IS FLOTATION SEPARATED AND DISCHARGED TO A SEPARATE AERATION REACTOR FOR M ...
