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.

Abstract: A system and method to treat wastewater or non-potable water using a reactor that is perforated at its bottom arranged in a vessel at a depth. Air pressure from an air grid at a reactor bottom induces an uplift of liquid and media to move highly aerated liquid through the media, which provides surfaces for microbial attachment and growth. An alkali porous material is suspended in the upswelling liquid that dissolves to reduce acidity and balance the pH of the liquor. The upswell in the reactor is at a higher elevation than the vessel giving directional discharge outlets head or velocity creating stirring and mixing to an area surrounding the reactor. Interchange of mixed and unmixed liquor is provided via the bottom perforations. Provision is also made for unit to cycle off and on so that the media can decant and for solids to settle out of the treatment unit.
