An air cleaning technology based on biotrickling filtration
developed in previous phases of the project was scaled up and
tested at the PSC swine grower-finisher facility. Results showed
that the air treatment units were effective in reducing the levels
of ammonia, dust, and odour from the airstream at the exhaust of
the grow-finish rooms by about 77%, 92%, and 75%, respectively.
Further work is needed to optimize the operation of these units in
terms of water usage and to assess its year-round performance.
