BAY VIEW Wastewater Treatment Plant
Fine Bar Screens and Pump Stations - Screens remove debris to prevent clogging and protect pumping equipment. Pump stations transport raw sewage to the treatment plant.
Aerated Grit Tanks - Remove five to ten tons of grit (sand, gravel, and other heavy solids) daily for landfill disposal.
Oil and Grease Skimming Tanks - Collect and transfer floatables to scum separation tanks. The sludge settles to the bottom and is pumped to the sludge thickeners.
Primary Clarifiers - Add polymer to the water to allow more solids to settle to the bottom and floatables to rise to the surface Floatables are skimmed and sent to a landfill. Solids are pumped to the digester tanks.
Aeration Tanks - Mix air with wastewater to promote growth of aerobic microorganisms which help to break down organic matter.
Final Clarifiers - Encourage floc, which contains microorganisms and organic material, to settle, leaving clarified water on the surface. This process creates return activated sludge, which is sent to the aeration tanks, and waste activated sludge, which is sent to dissolved air flotation.
Chlorine Contact Tank - Mixes the clarified water with chlorine to remove microorganisms before discharge into the Maumee River (required from April 1st through October 31st.)
Control Room - Allows plant personnel to monitor and control treatment processes via computer. Computers also tract the plant's performance for documentation in monthly operating reports.
Gravity Thickeners - Thicken raw primary sludge prior to placement in the Digester Storage and Mix Tank. Dilution water (final effluent) is added to keep the tanks from becoming septic. Thickener effluent is returned to the secondary tanks.
Dissolved Air Flotation - adds polymer to waste activated sludge and mixes it with pressurized water. Solid floatables are skimmed and pumped to the digestors. Remaining water flows back to the aeration tanks.
Anerobic Digestors - biologically stabilize sludge using anaerobic bacteria. This process produces methane gas, a source of energy for the plant.
Belt Filter Presses - add polymer to the sludge from the digestors. Sludge is then dewatered in belt filter presses, and disposed of at a landfill. Remaining water is returned to the aeration tanks.
