Abstract: A single-stage or multi-stage biological odor control treatment system for the removal of target vapor compounds from a contaminated air stream consisting of a first stage (onsite non-potable water treatment) where raw collection system non-potable water is extracted from the sewer collection system, screened and sprayed over a media bed where it is treated to secondary effluent water quality and is collected in a tank. The onsite non-potable water treatment system effluent is then pumped to the biological odor control system. This onsite non-potable water treatment system effluent is used for irrigating either a single media bed, or multiple media beds, which require continuous moisture and a source of nutrients. The microorganisms use the odorous compounds in the foul air stream as a food source. Treated air is then discharged to the atmosphere. The odor control treatment system drain water is then returned into the source containment collection point.
