Phosphorus fractions in manure from growing pigs receiving diets containing micronized peas and supplemental enzymes
January 1, 2006By O.O. Akinremi
Different livestock feeds manipulations have been reported to reduce the total P concentration in manure. Information on the influence of these dietary manipulation strategies on the forms of P in...
Bioleaching of zinc and copper from anaerobically digested swine manure: Effect of sulfur levels and solids contents
January 1, 2006By Shihwu Sung
Anaerobically digested swine manure (ADSM) generally contains high concentrations of zinc (Zn) and copper (Cu). These metals levels exceed the land application regulations of municipal biosolids of...
Characteristics of solids, BOD5 and VFAs in liquid swine manure treated by short-term low-intensity aeration for long-term storage
January 1, 2006By JUN ZHU
A laboratory-scale experiment presents data that reveal the temporal characteristics of solids, biochemical oxygen demand (BOD5) and volatile fatty acids (VFAs) in the aerated liquid swine manure for...
Effect of microbial additives combined with aeration on reduction of nutrients in swine manure
January 1, 2006By JUN ZHU
The research presented in this article evaluated a technique using manure additives (Sporzyme and activated sludge) coupled with aeration treatment in reducing nutrients from liquid swine manure....
Distribution of phosphorus in manure slurry and its infiltration after application to soils
January 1, 2006By Peter Vadas
Computer models help identify agricultural areas where P transport potential is high, but commonly used models do not simulate surface application of manures and P transport from manures to runoff....
Methane and carbon dioxide emissions from simulated anaerobic swine manure treatment lagoons under summer conditions
January 1, 2006
Most estimates of carbonaceous gas emissions from manure treatment lagoons are based on biogas production from anaerobic digesters, gases collected over covered lagoons, or the CH4 production...
Multi-component analysis of tetracyclines, sulfonamides and tylosin in swine manure by liquid chromatography-tandem mass spectrometry
January 1, 2006By A. M. Jacobsen
A multi-component method focussing on thorough sample preparation has been developed for simultaneous analysis of swine manure for three classes of antibiotic-tetracyclines, sulfonamides, and...
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...
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...
Ammonia emissions from swine waste lagoons in the Utah Great Basin
January 1, 2006
In animal production systems (poultry, beef, and swine), current production, storage, and disposal techniques present a challenge to manage wastes to minimize the emissions of trace gases within...
Environment - Manure Storage / Application
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...
Environment - Manure Storage / Application
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...
