Biofilters to Manage Odors and Air Emissions from Animal Feeding Operations
Channel: Livestock & Poultry Environ. Learning Community
Date: 2014-01-24

The biofilter video describes biofilters, their use, costs and effectiveness', management and operation considerations. People from two animal feeding operations that use biofilters discuss their use, costs and management.
Biofilters are used to treat odorous air from mechanically ventilated livestock barns and manure storage units. Odorous air is blown through a porous media-- wood chips are commonly used in the Midwest--where microorganisms and fungi grow and remove the odorous gases. Well-managed biofilters can reduce odor emissions by up to 95 percent. For more see http://www.extension.org/67057
