A full-scale Biofor® system from Ondeo Degremont was selected as the most cost-effective solution. The first two stages will treat an average flow of 44.0 mgd and a peak flow of 70.0 mgd. The third stage will treat an average flow of 17.0 mgd and a peak flow of 49.5 mgd.
Binghamton-Johnson City, Joint Sewage Treatment Plant, Vestal, New York U.S.A.: Three-Stage Biofor® System
A 5-month pilot study of a threestage biological filter arrangement for carbon removal, nitrification and denitrification was conducted. Based on the loading criteria established by the pilot study, it was determined that the full-scale expansion would fit within the existing site limits. It would also allow elimination of the peak wet weather bypassing associated with the current activated sludge.
