Can a biotrickling filter remove Ammonia?

Yes, biotrickling filters are very effective in removing ammonia (NH3) from odorous air streams. This is achieved through the primary processes of biological oxidation of NH3 to nitrate (NO3-) and scrubbing. For air streams that contain hydrogen sulfide, the sulfide is oxidized to sulfate thus reducing the water pH and increasing the solubility and removal of ammonia through the irrigation water.
