Utilizing By-Products To Clean Air in Swine Buildings
The Animal and Poultry Waste-Management Center

This project was designed to evaluate the effect on odor of removing dust from the air in hog barns and to determine whether there is a need for biofiltration in addition to dust removal to reduce odor. A gravimetric dust meter and aerosol particle counter were purchased and used to help evaluate the effect of dust filters and biofilters on odor from a swine building. Both dust filters and biofilters reduced odor substantially. Biofilters were not considered economically feasible, however, because they require increased air pressure to move air through the filters. Increasing air pressure was seen as too costly to make biofilters economically feasible.
