Removal of airborne swine dust by electrostatic precipitation
January 1, 1995
An electrostatic precipitator used in conjunction with a recirculation duct was developed to remove airborne pig dust from an environmental chamber. The collection efficiency of the precipitator was...
Potential reduction of struvite formation from anaerobic swine lagoon effluent by treatment in constructed wetlands
January 1, 1994By Dennis M. Sievers
Effluents from both cells of a two-cell anaerobic lagoon system treating flushed swine waste from the University of Missouri Swine Farm were treated in parallel constructed wetlands - submerged flow...
Headspace analysis of malodorous compounds from swine wastewater under aerobic treatment
January 1, 1994By A. Chen
Static headspace sampling and gas chromatograph (GC) analyses were used to monitor the concentration of malodorous compounds (volatile fatty acids (VFA), phenol, p-cresol, indole, and skatole)...
Effects of swine lagoon effluent and commercial fertilizer applications on phosphorus status of an acid and alkaline soil
January 1, 1994By Ardeshir Adeli
Two separate field experiments were conducted in Brooksville, Mississippi to evaluate the effects of swine lagoon effluent relative to inorganic fertilizer at equivalent rates on phosphorus (P)...
Denitrification in a Coastal Plain Riparian Zone Contiguous to a Heavily Loaded Swine Wastewater Spray Field
January 1, 1994
Riparian zones are recognized worldwide as important landscape features that are able to buffer streams from pollutants, particularly nitrogen. The objectives of this experiment were to 1) assess the...
Swine lagoon effluent as a source of nitrogen and phosphorus for summer forage grasses
January 1, 1994
Efficient crop utilization of N and P derived from anaerobic swine (Sus scrofa domesticus) lagoon effluent is critical to minimizing offsite nutrient movement. The objective of this study was to...
Removal of ammonia and odors from contaminated air in animal houses by a ferroelectric plasma reactor
January 1, 1994
The objective of this work was to develop an electric air-cleaning system for animal houses. An a.c.-powered ferroelectric packed-bed plasma reactor was tested to destroy ammonia and odours in the...
Gaseous nitrogen emissions from anaerobic swine lagoons: ammonia, nitrous oxide, and dinitrogen gas
January 1, 1994
Seventy-five percent of swine (Sus scrofa) production systems in North America use anaerobic or liquid-slurry systems for waste holding or disposal. Accurate emissions data and emission factors are...
A computer model for predicting ammonia release rates
January 1, 1994
A computer model for predicting ammonia release rates from manure pits in pig buildings is presented. The model couples ammonia diffusion and generation in the manure with ammonia release from the...
Comparability of anaerobic swine lagoon effluent to commercial fertilizer on soil nutrient dynamics
January 1, 1994By A. Adeli
The effects of swine effluent relative to commercial fertilizer on nutrient dynamics in two soils were studied in Mississippi, USA. Swine effluent and commercial fertilizer were applied to...
Designing Riparian Buffer Systems for Utilization and Treatment of Effluent
January 1, 1993By R. K. Hubbard
Management techniques for using riparian buffer systems to utilize and treat agricultural effluents are being developed in at the Coastal Plain Experiment Station, Tifton, GA. Riparian systems...
Treatment of Swine Wastewater Using a Saturated-Soil-Culture Soybean and Flooded Rice System
January 1, 1993By P. G. Hunt
Constructed wetlands have potential for treatment of livestock wastewater, but they generally contain wetland plants rather than agronomic crops. We evaluated two agronomic crops,...
