Three Options for Cleaning Barn Exhaust Air

Reducing aerial emissions and improving air quality is a common goal in the livestock and poultry industries. This webinar will present three approaches to reducing aerial emissions from barn exhaust air, using combinations of wet scrubbing, electrostatic precipitation, filtration and enhanced dispersion. The efficacy of an odor removal system using electrostatic particle ionization and a geotextile fence was evaluate at commercial swine production building in Iowa with the system showing removal of both odor and particulate. While wet-scrubbers have been used for years for emission control, these systems are typically expensive. A low-cost version, using a trickling water curtain as the wet scrubber was developed to provide a lower cost option. The webinar will describe the approaches, and highlight research conducted at production-scale barns.

An application for continuing education credit for Certified Crop Advisors (CCAs) and members of the American Registry of Professional Animal Scientists (ARPAS) will be submitted.
