Air Emission and Energy Usage Impacts of No Pit Fans in a Wean to Finish Deep Pit Pig Facility

What Is Being Measured?

The objectives of this research project are to monitor the indoor air quality of a deep-pit; wean-to-finish pig building over one pig-growth cycle (six months) by semi-continuously measuring concentrations of ammonia (NH3), hydrogen sulfide (H2S), carbon dioxide (CO2), methane (CH4), and volatile organic compounds (VOCs) and intermittently measuring particulate matter (PM10) and odor.…

Odor Emissions and Chemical Analysis of Odorous Compounds from Animal Buildings

Why Study Odor Emissions from Animal Housing?

  • To determine odor emission characteristics by using common protocols and standardized olfactometry, from four mechanically-ventilated National Air Emissions Monitoring Study (NAEMS) sites, two dairy and two swine.
  • To develop a comprehensive chemical library that delineates the most significant odorants, and correlate this library with olfactometry results.

Clearing the Air on Biofilters

Biofilters have been widely adopted to filter gas, odor and particulate matter from livestock facilities. However, the science behind “how they work” and the configurations that are in practice are continually evolving. This webinar discusses past and present applications of biofilters, on-going research to better design and manage biofilters, and how to incorporate biofilters as part of an environment control system.This…
