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...
Modeling ammonia volatilization from surface-applied swine effluent
January 1, 1998By D. L. Nofziger
Ammonia volatilization is an important issue in agricultural production and environmental protection. Experimental methods and numerical models exist to estimate the rate and amount of ammonia...
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...
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...
