The piggery industry is important both worldwide and in Canada, but swine production sites can emit substantial amounts of aerial contaminants. Biological treatment systems, such as biotrickling filters (BTF), have the potential to treat these emissions which are generally characterised by low concentrations and very high flow rates. The main objective of this study was to test the effect of certain operating parameters on the performance of BTFs treating swine exhaust air.
