Evaluation of a permeable, 5 cm thick, polyethylene foam lagoon cover
January 1, 2000
Anaerobic lagoons and liquid manure storage basins are widely used for the treatment and storage of livestock and poultry manure. Although relatively inexpensive to construct, these devices have been...
Dynamics of Pig Slurry Nitrogen in Soil and Plant as Determined with 15N
January 1, 2000
The fate of pig (Sus scrofa) slurry labeled with 15N was investigated when applied on a clay soil (fine, mixed, frigid, Typic Humaquept) and a sandy loam (loamy, mixed, frigid, Typic Dystrochrept)...

Conceptual model for ammonia and odor production and ammonia emission from swine anaerobic lagoons
January 1, 2000
A model that predicts the concentration of ammonia and volatile fatty acids as odor indicators was developed for anaerobic lagoons using Monod kinetics. The model used average measured parameter...
Evaluation of two-stage anaerobic sequencing batch reactor systems for animal wastewater treatment
January 1, 2000
Anaerobic treatment of screened swine and dairy manure was studied in the laboratory with two-stage anaerobic sequencing batch reactor (ASBR) systems. The effects of anaerobic treatment on odor...
Geotextile covers to reduce odor and gas emissions from swine manure storage ponds
January 1, 2000
Odor, hydrogen sulfide (H 2 S), ammonia (NH 3 ), and volatile organic compounds (VOC, GC/MS analytes) were measured between May and October 2000, and between April and October 2001 at sites...
Malodor reduction in liquid swine manure treated in subsurface flow constructed wetlands
January 1, 2000
Anecdotal evidence has suggested that constructed wetlands can reduce malodor in liquid livestock wastes. This study quantified the concentrations of two malodorous compounds (dimethyl disulfide and...
Hydrogen sulfide production from stored liquid swine manure: a laboratory study
January 1, 2000By Jactone Arogo
The production of hydrogen sulfide from stored liquid swine manure as influenced by the manure settling characteristics and the initial sulfate concentration was studied in the laboratory. The...
Biofilter media mixture ratio of wood chips and compost treating swine odors
January 1, 2000By K. A.|Nicolai|R. E. and Janni
Biofilter media mixtures were compared in 18 pilot-scale biofilters treating pit gases from a swine facility. The compost and wood chips mixtures ranged from 100% wood chips to a 50-50 blend in 10%...
The use of an air supported pneumatic structure to reduce earthen lagoon gas emissions
January 1, 2000
Gas emissions and odour control is an increasing concern as swine commercialization expands, since odour continues to be a limiting factor for future growth. Present odour control technologies for...
