Biotrickling filters are easier to manage and are smaller in size compared to other exhaust air filtration technologies. To ensure the best design is developed, further work is needed to see what performs best in swine production facilities. An air treatment unit with air cleaning technology to reduce exhaust air odour from a grower-finisher facility was developed. Using this air filtration unit, ammonia, odour and dust concentrations decreased before being released to the environment by 77%, 75% and 92%, respectively. Water consumption increased as more contaminants were removed from the air
