The Kenton County Airport Board (“KCAB”) will receive bids for Two (2) Digester Tanks Aeration Equipment Replacement. KCAB is soliciting bids from qualified vendors to design and supply a coarse bubbler aeration system to replace the existing fine bubbler aeration system in two digester tanks. The two digester tanks and associated aeration equipment were installed in 2004. In 2006, the BIOLAC system was added and the operation of the tanks changed from sequence batch reactors to digesters. The digester tanks are currently equipped with mechanical mixers that provide primary mixing within the tanks. The existing fine bubbler system provides aeration, but due to the change in operation of the tanks from sequence batch reactors to digesters, creates operational challenges when decanting. Consequently, KCAB would like to update this to a coarse bubbler aeration system. Additionally, the PVC piping has begun to reach its end of useful life and needs to be replaced.
Submission Deadline: May 7, 2026, 2:00 p.m. Eastern Time
