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...
Nitrification treatment of swine wastewater with acclimated nitrifying sludge immobilized in polymer pellets
January 1, 2000By Matias B. Vanotti
Nitrification of ammonia (NH4+) is a critical component for improved systems of animal wastewater treatment. One of the most effective processes uses nitrifying microorganisms encapsulated in polymer...
Denitrification in marsh-pond-marsh constructed wetlands treating swine wastewater at different loading rates
January 1, 2000
Denitrification in constructed wetlands can be very important in the treatment of swine lagoon effluent when land application areas are limited. The objectives of this investigation were to determine...
Ventilation, feed, and loading methods effects on hydrogen sulfide emissions from swine slurry
January 1, 2000
Four treatments were evaluated for their effect on emission of H2S of swine slurry stored in simulated beneath floor pits. The treatments were: (1) batch load without ventilation; (2) batch load with...
Swine wastewater treatment in a two stage sequencing batch reactor using real-time control
January 1, 2000By K. V. Lo
A laboratory scale two-stage sequencing batch reactor (TSSBR) was used to study the effectiveness of pH as a real-time control parameter in swine wastewater treatment. A Ringlace media was inserted...
Performance of a pond aeration system for treating anaerobic swine lagoon effluent
January 1, 2000By Philip W. Westerman
The waste treatment system presented in this article is one of the alternative waste management systems that have been evaluated for swine farms in North Carolina. The treatment system was designed...
