Reducing odours can help reduce possible environmental impacts and improve how acceptable they are to be near rural communities. Air cleaning technology was developed to reduce odour from the exhaust air from swine facilities. A bio-trickling air treatment unit was designed; it is smaller than other exhaust air filtration systems and easier to manage. It is also easy to maintain, adaptable to different facilities and is low in cost. The exhaust air is cleaned by a wetted filter media and a biofilm while passing through the wall. Ammonia, dust and odour levels were reduced by 77%, 92% and 75%, respectively. This bio-trickling air treatment unit can help alleviate emissions and odours produced by swine facilities.
