Agricultural biofilters - reflections on a decade of research


Project Leader:  Danny Mann, Dept. of Biosystems Engineering


Over the past decade, I have had the opportunity to research the use of biofiltration for treatment of odour from hog barns. A total of 8 papers have been published in refereed scientific journals (see listing at conclusion of paper). In addition to the knowledge contained in those papers, other information has been reported in project reports and student theses. The purpose of this document is to pull together my observations and conclusions related to the use of biofiltration for the treatment of hog odours. It should be recognized that some of the observations included in this document lack sufficient scientific evidence to be considered scientific truths.
