Swine effluent irrigation rate and timing effects on bermudagrass growth, nitrogen and phosphorus utilization, and residual soil nitrogen
January 1, 1998By A. Adeli
Maximizing utilization of effluent nutrients by forage grasses requires a better understanding of irrigation rate and timing effects. This study was conducted in 1998 and 1999 on a Vaiden silty clay...
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...
Experiences with a biofilter on a slatted floor hog barn
January 1, 1998
A biofilter was installed for the removal of odorous gases from the pit ventilation air of a slatted floor pig finishing barn and was studied over a 2 year period. The biofilter was effective 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.
Application of Mixed and Aerated Pond for Nitrification and Denitrification of Flushed Swine Manure
January 1, 1998By Philip Westerman
A nitrification/denitrification system for flushed swine manure was evaluated for treating manure from 3000 finishing pigs. The system consisted of a pond with a mixing zone for denitrification...
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...
Covered anaerobic lagoon system for swine waste treatment and energy recovery
January 1, 1998By Jiayang Cheng
A covered anaerobic lagoon system for swine manure management has been evaluated for its performance. The system consists of a covered anaerobic lagoon for primary treatment and a conventional lagoon...
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,...
Dispersion of Volatile Organic Compounds around Swine Production Facilities in the United States
January 1, 1998
Dispersion of odors, gases, and particulates from swine production and manure storage facilities creates a problem with neighbors. It is assumed that all materials emitted by production units rapidly...
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...
