Effects of chemical amendments on the gaseous emissions from swine manure
January 1, 1999
Control of emission of gases such as ammonia (NH3), hydrogen sulfide (H2S), carbon dioxide (CO2) and methane (CH4) is a major concern for large-scale swine producers. The use of chemical amendments...
Field evaluation of a wet pad scrubber for controlling dust and odor emissions
January 1, 1999
An evaporative cooling pad system was installed upwind of exhaust fans and downwind of pigs in a tunnel ventilated finishing building to determine effectiveness in reducing dust, ammonia, and odours....
Odor and hydrogen sulfide emissions during agitation and pumping of stored dairy and swine manure in Minnesota
January 1, 1999
Odour and hydrogen sulfide (H2S) release during agitation and pumping of stored manure can often cause neighbours to complain. Increased levels of H2S inside or near animal buildings impact the...
Design and evaluation of an open biofilter for treatment of odour from swine barns during sub-zero ambient temperatures
January 1, 1999
Open biofilters have previously been shown to reduce odour from typical swine production facilities, but it was not known whether the exhaust air contained sufficient heat to prevent the biofilter...
Reduction of odour and gas emissions from swine buildings using canola oil sprinkling and alternate diets
January 1, 1999
This three year project evaluates the impact of four different canola oil application rates combined with specific diet formulations on odour and gas emissions from grower-finisher swine buildings....
Optimization of a sprinkling system using undiluted canola oil for dust control in pig buildings
January 1, 1999
An oil sprinkling system has been designed to control dust levels in pig buildings using undiluted crude canola oil and was previously tested over a two-week period. The system was tested again over...
Dust and odor emissions from tunnel ventilated swine buildings in North Carolina
January 1, 1999
Tunnel ventilation of swine buildings conveys odorous dust and gases out of the production buildings. Measurement of dust and odour levels and other environmental parameters is necessary for...
N-source effects on temporal distribution of NO3-N leaching losses to subsurface drainage water
January 1, 1999By R. S. Kanwar
Understanding the temporal distribution of NO3-N leaching losses from subsurface drained ?tile? fields as a function of climate and management practices can help develop strategies for its...
Evaluating peats for their capacities to remove odorous compounds from liquid swine manure using headspace "solid-phase microextraction"
January 1, 1999
This paper reports on research designed to investigate the capacities of different highly characterized peats to remove odorous compounds from liquid swine manure (LSM). Peat types representing a...
Potential for reduction of odorous compounds in swine manure through diet modification
January 1, 1999
Recent public concern about air pollution from pork production units has prompted more research to develop methods to reduce and control odors. Masking agents, enzymes and bacterial preparations,...
Swine manure storage covers for odor control
January 1, 1999By Chuck Clanton
Twenty-one, 750-L (200 gal) polyethylene tanks were filled with swine manure. Air samples were collected 24 and 48 h after each manure addition. The samples were tested for odor strength using a...
Odor emission from mixtures of ground swine carcass material and liquid swine waste
January 1, 1999By Chuck Clanton
Mixing ground swine carcasses with the manure waste stream is a new concept currently being researched as an alternative carcass-disposal method. A concern has been raised with this method regarding...
