Document Description
Proposal to eliminate odors form the sanitary sewer system by collecting foul air from the sewer, removing the odorous compounds and then released the "scrubbed" air into the atmosphere. The North Outfall Replacement Sewer Air Treatment Facility will include a two-stage treatment system. The first stage will involve air treatment through two beds of a single media in biotrickling filters (BTFs), which will remove 99% of the hydrogen sulfide and volatile organic compounds (VOCs) in the sewer air. The second stage will consist of an activated carbon treatment system, which will remove the remaining VOCs and odors. The treatment process is biological and uses no chemicals; this technology is considered environmentally-friendly. The 3-bed BTF facility will be on a concrete pad approximately 72 feet in length and 24 feet in width. Each of the BTF tanks will be approximately 12.4 feet in diameter and 29 feet tall. The activated carbon treatment system will consist of four tanks, each about 12 feet high and 12 feet wide. Treated air will be conveyed to a stack and discharged into the atmosphere.
