Odor flux measurements at a facultative swine lagoon stratified by surface aeration
January 1, 2002
Odour-related complaints are a major concern of pork producers. Open manure storage and treatment facilities such as uncovered anaerobic treatment lagoons are a major contributor to odour nuisance....
Fate of Salmonella following application of swine manure to tile-drained clay loam soil
January 1, 2002
Land application of animal manure is an important means of utilization of nitrogen and phosphorus. However, the presence of pathogens in manure and their occasional leaching into subsurface water has...
Nitrous oxide and ammonia fluxes in a soybean field irrigated with swine effluent
January 1, 2002
In the USA, swine (Sus scrofa) operations produce more than 14 Tg of manure each year. Approximately 30% of this manure is stored in anaerobic lagoons before application to land. While land...
Effects of Solids Separation and Time on the Production of Odorous Compounds in Stored Pig Slurry
January 1, 2002
Fresh pig faeces were separated into seven different liquid portions with particle size ranges pig manure through a series of seven American Society for Testing Materials (ASTM) standard wire screen...
Carvacrol and thymol reduce swine waste odor and pathogens: stability of oils
January 1, 2002
An incomplete anoxic fermentation of livestock waste results in offensive odour emissions. Antimicrobial additives may be useful in controlling odour emissions and pathogens. Natural antimicrobial...
Oxidation kinetics of phenolic and indolic compounds by ozone: applications to synthetic and real swine manure slurry
January 1, 2002By Jerry J. Wu
In this study, an oxidation model combining the mass transfer of ozone and ozonation kinetics was developed to predict the degradation of several phenolic and indolic compounds in a semi-batch...
Summertime concentrations and emissions of hydrogen sulfide at a mechanically ventilated swine finishing building
January 1, 2002
Hydrogen sulfide (H2S) concentration and emission at a modern mechanically ventilated swine finishing building with a deep pit were continuously measured for three summer months. The building is...
Simulating Swine Manure Transport in Soils Using the Mobile-Immobile Contaminant Transport Model
January 1, 2002By Victor B. Ella
Modeling swine manure transport is an important initial step not only in understanding the behavior of this potential contaminant in the subsurface environment but also in providing a basis for...
Swine Wastewater Treatment in an Integrated System of Anaerobic Digestion and Duckweed Nutrient Removal
January 1, 2002By J. Cheng
Organics destruction and nutrient uptake in an integrated pilot system of anaerobic digestion and duckweed nutrient removal for swine wastewater treatment were monitored under field conditions. Raw...
Solid-liquid separation of flushed swine manure with PAM: effect of wastewater strength
January 1, 2002By Matias B. Vanotti
Organic polymers are useful to increase separation of suspended solids and reduced carbon compounds from liquid swine manure. Along with the solids, there is a capture of the nutrients associated...
