Title
Authorizing the appropriation and expenditure of $350,000 from the Sanitary Sewer Replacement Fund for the Aeration Tank Cleaning Project at the Bay View Water Reclamation Plant; authorizing the mayor to accept bids and award contracts to facilitate the Aeration Tank Cleaning Project; and declaring an emergency.
Body
SUMMARY & BACKGROUND:
The Bay View Water Reclamation Plant houses nine (9) aeration tanks, which are used for the activated sludge biological treatment process in the Secondary Treatment area. Each tank utilizes around 1200 air diffusers to provide oxygen to the microorganisms to break down the organics in the activated sludge treatment process. These air diffusers require routine cleaning and sometimes replacement in order to effectively diffuse the oxygen to the microorganisms. This Ordinance will provide funds to clean one aeration tank from accumulated sludge and perform required cleaning, repairs and/or replacement of parts such as, air diffusers, sleeves, clamps, piping and valves as needed. This cleaning project will increase the air diffusion efficiency which will optimize the generation of good mixed liquor for better clarification of water in the Secondary Clarifiers. Having good mixed liquor will help maintain compliance with the Plant's National Pollutant Discharge Elimination System (NPDES) discharge permit.
