<p>An odor control system consisting of a cylindrical bio-scrubber (20) packed with means providing an extensive surface area over which liquid media is caused to cascade, an oxidation pond (22) containing selected microorganism in a fluid media, and means (25) for introducing gases to be treated into the bioscrubber (20) while concurrently causing microbial-impregnated fluid from the oxidation pond (22) to flow through and into contact with effluent gases passing through the bio-scrubber (20), thereby to effect transport of gases to the oxidation pond (22) where volatile organic compounds are metabolically destroyed. When necessary to achieve optimum odor reduction a further element can be added to the overall combination in the form of a biofilter (30) through which gases emanating from the bio-scrubber (30) are passed before their release to the atmosphere.</p> |
