Review of the use of aerobic thermophilic bioprocesses for the treatment of swine waste
January 1, 2006By Pierre Juteau
For 40 years, aerobic thermophilic (AT) processes have been presented as a possible way of treating liquid manure, especially swine wastes. If they are well designed, bioreactors can be self-heating...
Characterization of volatile organic compounds and odorants associated with swine barn particulate matter using solid-phase microextraction and gas chromatography-mass spectrometry-olfactometry
January 1, 2006By Jacek A. Koziel
Swine operations can affect air quality by emissions of odor, volatile organic compounds (VOCs) and other gases, and particulate matter (PM). Particulate matter has been proposed to be an important...
Response of selected soil physical and hydrologic properties to manure amendment rates, levels, and types
January 1, 2006By Fares
Manure amendments affect several soil physical and hydrologic properties. The objectives of this study were to evaluate the effect of (i) manure amendment rates (0, 168, 336, and 672 kg total N...
Modeling sources of gaseous emissions in a pig house with recharge pit
January 1, 2006By Peter Kai
Ammonia, methane, and odor from a fully slatted pig housing facility equipped with a pit-recharge manure system were modeled with a view to quantify the sources of ammonia, methane, and odor...
A two-step fed SBR for treating swine manure
January 1, 2006By JUN ZHU
Specially designed sequencing batch reactors (SBR) may be a solution to disposal of massive pig manure, rich in nitrogen (N) and phosphorus (P), produced by concentrated swine operations. In this...
Use of polyacrylamide in simulated land application of lagoon effluent: Part II. Nutrient loss
January 1, 2006By Dennis C. Flanagan
Land application of agricultural wastewater can contribute to eutrophication of water bodies by increasing the quantities of dissolved and particulate nutrients that are transported in runoff during...
Treatment of swine manure effluent using freshwater algae: Production, nutrient recovery, and elemental composition of algal biomass at four effluent loading rates
January 1, 2006By Walter W. Mulbry United States Department of Agriculture
Cultivating algae on nitrogen (N) and phosphorus ( P) in animal manure effluents presents an alternative to the current practice of land application. The objective of this study was to determine how...

Disposal of Swine Lagoon Sludge with Nutrient Recovery
December 21, 2005By M. Todd See
Gasification offers many advantages for processing undesirable waste materials. Tests on gasifier emissions reveal very low levels of NOx, SOx and volatile organic carbons in the flue gas, well...

Disposal of Swine Lagoon Sludge with Nutrient Recovery
December 21, 2005By Dr. M. Todd See
Sludge accumulation in lagoons reduces their treatment efficiency over time
and, ultimately, may cause the decommissioning of the lagoon. Gasification is an ideal
technology for sludge disposal since...

Control of Salmonella by segregated early weaning, topical disinfection and administration of sodium chlorate
December 15, 2005By Peter Bahnson
The results of this study document that sodium chlorate / nitrate / lactate, used alone or combination with early weaning and/or topical disinfection can be effective in reducing Salmonella...
