Assessing the impact of swine sulfur intake from drinking water on odor and gaseous emissions and manure nutrients
February 12, 2007By Bernardo Predicala
The impact of a specific input to the pig on the resulting air emissions and manure characteristics was assessed. Specifically, the impact of varying sulfate levels in drinking water on odor and...

Assessing the impact of swine sulfur intake from drinking water on odor and gaseous emissions and manure nutrients
February 12, 2007By Bernardo Predicala
To assess the impact of inputs to the pig on air quality and manure management, a study was conducted to assess the effect of varying sulfate levels in drinking water on odor and gaseous emissions...

Partitioning between pit and wall emission streams of hydrogen sulfide, ammonia, particulate matter, and odor from deep-pit pig finishing facilities for decision support in selecting emission control technologies
December 1, 2006By Larry D. Jacobson
The results of this study show limited benefit to exhausting a portion of air through the pit rather than through the wall for deep-pit pig finishing barns. This conclusion comes from similar indoor...

Developing a Decision Support Tool to Optimize Swine Production Facility Layout to Minimize Downwind Air Quality Impacts
November 13, 2006By Thomas J. Sauer
These model experiments of air flow characteristics suggest that when swine confinement buildings are oriented so that the approaching wind is parallel to the buildings the wind is reduced less than...

Quantification of gas and odor emissions from swine wean-finish facilities
May 15, 2006By Alan Sutton
The most significant change seen in the swine industry has occurred over the last sixty years. We have seen a shift from many farms producing a limited number of pigs to a small number of large...

Quantification of gas and odor emissions from swine wean-finish facilities
May 1, 2006By Alan Sutton
A total of 960 pigs (equal barrows and gilts) were used in a 2 x 2 factorial, wean to finish
experiment to determine the effects of diet (control, CTL vs. low nutrient excretion, LNE)
and manure pit...

DESIGN SPECIFICATION FOR A VERTICAL BED BIOFILTER
July 31, 2005By Richard Nicolai
A vertical biofilter may be a good option for reducing odor and gas emission when not enough space is available to install a horizontal biofilter. The vertical biofilter is cylindrical with the...
