ABSTRACT
The air in livestock buildings contains gases, odors, dust particles and microorganisms that are emitted by the ventilation system into the surrounding environment. Odor and pollutant emissions can be a nuisance for residents living in the close proximity of livestock buildings. Dust particles, bacteria and ammonia were sampled at two positions. One sampling position was after the exhaust air left the weaner room and one after the scrubber unit. Both sampling positions were shielded to avoid atmospheric influences. The post-filter concentrations of inhalable particles and ammonia were significantly reduced by the filter device. The concentrations of respirable particles did not change significantly post-filter, indeed, they numerically slightly increased. Air-scrubbing is a proven technology used for pollutant emission control in industrial settings. In the livestock industries, there is a renewed interest in removing pollutants from air emitted from buildings housing livestock.
