The new Strodes Creek Wastewater Treatment Plant includes a 24.0 MGD influent pump station/screenings facility designed to provide complete pumping redundancy and influent flow measurement. Preliminary treatment includes two mechanical fine screens with an integral screw conveyors and a manual bypass coarse bar screen. All screenings will take place before the wastewater is pumped.
Following preliminary treatment, the wastewater enters a series of basins to begin the biological treatment process. Anaerobic basins are designed to promote the growth of phosphorus-storing microorganisms, providing biological phosphorus removal as required by the Kentucky Division of Water. Four large oxidations ditches provide dissolved oxygen treatment to allow for the removal of 640 mg/L of BOD following the phosphorus removal system.
Following the biological processes, four 105-foot diameter final clarifiers remove suspended solids. The clarified effluent is disinfected using ultraviolet light and oxygenated via a re-aeration ladder. Effluent from the facility is measured using a transit-time flow meter prior to being discharged into Strodes Creek. Waste solids are injected with polymer, dewatered using two new gravity belt thickeners placed above the two existing belt filter presses, and hauled to an approved landfill.
