Constructed Wetlands as Remediation Tools for Shallow Groundwater Contaminated by Swine Lagoon Seepage
January 1, 2000By Michael R. Burchell II
Constructed wetlands have been implemented as treatment systems for wastewater. Wetlands may remove nutrients and sediment through biogeochemical functions such as adsorption, nitrification,...
Lagoon-biogas emissions and carbon balance estimates of a swine production facility
January 1, 2000
Gaseous emissions from animal manure storage facilities can contribute to global greenhouse gas inventories. Biogas fluxes were measured for one year from a 2-ha anaerobic lagoon that received waste...
Solids-liquid separation of swine manure for odor control
January 1, 2000
Fresh swine manure was separated into seven different liquid portions with size-ranges; <2.0, <1.4, <1.0, <0.5, <0.25, <0.15 and <0.075 mm, respectively. The separation was...
The effectiveness of aerobes used as manure additives for swine manure odor control
January 1, 2000By JUN ZHU
The objective was to examine the growth of aerobic bacteria in swine manure when used as manure additives for odor control. Hydrogen peroxide was used as an oxygen provider added to the test manure...
Odor and gas release from anaerobic treatment lagoons for swine manure
January 1, 2000By A.J. Heber
Odour and gas release from anaerobic lagoons for treating swine waste affect air quality in neighbouring communities but rates of release are not well documented. A buoyant convective flux chamber...
Correlation of odor detection thresholds with concentrations of hydrogen sulfide, ammonia and trace gases emitted from swine manure
January 1, 2000
Several odour measurement methods were used during a 42-day test of commercial manure additives. Air samples were taken biweekly from the ventilated headspaces of 39 laboratory reactors containing...
A farm-scale test of nitrogen assimilation by vegetated buffer systems receiving swine lagoon effluent by overland flow
January 1, 2000By Robert K. Hubbard|Soil Scientist
A farm-scale study was conducted from 2000 to 2004 to determine the effectiveness of grass-forest vegetated buffers in assimilating nitrogen (N) from overland flow application of swine lagoon...
Designs for windbreak walls for mitigating dust and odor emissions from tunnel ventilated swine buildings
January 1, 2000By R.W. Bottcher
Although windbreak walls have traditionally been applied to reduce ground-level wind speeds and enhance snow deposition, windbreak walls have also recently been placed downwind of animal buildings in...
Swine operations: comparison of biological filter media for odor control and wastewater treatment
January 1, 2000
Researchers at Mississippi State University have been studying the effectiveness of the attached growth process for swine wastewater treatment and odor abatement for the past three years. Organic...
Survival of zoonotic pathogens in soils and runoff water after application of swine manure
January 1, 2000By Sagar M. Goyal
Because of increased scrutiny of manure handling practices, it is important to determine the most appropriate practices for manure application on soil. This study was undertaken to determine the...
