Rates and controls on denitrification in an agricultural soil fertilized with liquid lagoonal swine waste
January 1, 1998
Under laboratory conditions, we studied rates and controls on denitrification and denitrification potential (denitrifying enzyme activity, DEA) in agricultural soils in the southeastern United States...
Antimicrobial residues in animal waste and water resources proximal to large-scale swine and poultry feeding operations
January 1, 1998
Expansion and intensification of large-scale animal feeding operations (AFOs) in the United States has resulted in concern about environmental contamination and its potential public health impacts....
A laboratory study of an aerated lagoon bio-blanket for swine manure odor control
January 1, 1998
The effectiveness of an aerated, submerged bio-blanket for controlling the release of odorous and volatile compounds from pig manure storage lagoons was examined. Hydrogen peroxide was used as an...
Odor carrying characteristics of dust from swine facilities
January 1, 1998
Odour nuisance has become a major problem in the pig industry. Foul-smelling dust plays a major role in the spreading of odour. Gas chromatography equipped with a flame ionization detector has...
Anaerobic treatment of animal wastewater for odor control
January 1, 1998
Anaerobic treatment of pig and dairy manure was studied in the laboratory with 2-stage anaerobic sequencing batch reactor (ASBR) systems. The effects of anaerobic treatment on odour control in...
Ammonia emissions from a High-RiseTM swine finishing facility
January 1, 1998
Ammonia concentrations of exhaust air from a 960-head, High-RiseTM swine finishing facility and of air downwind from the facility were monitored during the facility's first year in operation,...
Testing of peats for removal of odors from liquid swine manure
January 1, 1998
This paper reports on research designed to investigate the capacities of different kinds of peat to remove odor-causing compounds from liquid swine manure (LSM). Two experiments were conducted. In...
Odor reduction bioreactor system
January 1, 1998
A laboratory scale odour reduction bioreactor system was designed and developed to provide initial evaluation of kenaf (Hibiscus cannabis) as a potential attached growth media for odour abatement and wastewater remediation of swine wastewater.
Outdoor hydrogen sulfide concentrations near a swine feeding facility
January 1, 1998
Ambient hydrogen sulfide concentrations were monitored for several months at the property line of a wean-to-finish swine production facility. Data was analysed to determine apparent influences of...
Volatile fatty acid emission during composting of swine waste amended with sawdust as a measure of odor potential
January 1, 1998
Offensive odours which evolve during the decomposition of swine waste have resulted in complaints from neighbours in agricultural areas. This study chronologically monitored the emissions of volatile...
An inflatable cover for a concrete manure storage in a swine facility
January 1, 1998
This study demonstrated that an air supported inflatable manure storage cover could be an economical and effective method for reducing odour emission into the atmosphere. To construct this inflatable...
Ammonia emissions from composting hog manure amended with sawdust under continuous and intermittent aeration
January 1, 1998
Ammonia emissions during composting of hog manure mixed with sawdust were studied in four runs comprising a total of 22 pilot-scale reactor vessels. These four runs extended previous work and both...
