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...
Odor and gas reduction from sprinkling soybean oil in a pig nursery
December 1, 1997
Daily sprinkling of very small amounts of vegetable (soyabean) oil inside a pig nursery facility reduced the odour, hydrogen sulfide (H2S), and total dust levels of the air inside the barn and in the...
Reduction of nutrients and odor in swine manure with sequencing batch treatment and intermittent aeration
