Butte des Morts Beach Road, Neenah, Wisconsin Receiving Water And Location: Little Lake Butte des Morts in Little Lake Butte des Morts of Fox River (lower) in Winnebago County Brief Facility Description and Summary of Proposed Changes: Domestic, commercial, and industrial wastewaters are received at the plant from the Village of Fox Crossing, the Town of Grand Chute, the Village of Greenville, and the Town of Clayton. Along with wastewater, hauled in waste (holding tanks, septic waste) is also received for treatment at this facility. The wastewater passes through fine screens, grit removal, and primary clarification prior to entering one of three trains of IFAS (Integrated Fixed Film Activated Sludge) aeration basins. Ferric chloride is added for phosphorus removal. After secondary clarification in one of five final clarifiers, effluent passes through Ultraviolet (UV) lights for disinfection and is discharged into Little Lake Butte des Morts. Solids (primary sludge, waste activated sludge) are treated using ATAD (autothermo thermophilic aerobic digestion) digesters. Solids are stored in a sludge storage tank prior to being fed into one of two ThermAir digesters. Following the ThermAir digesters, sludge is moved through the SNDR (storage nitrification denitrification reactor) tanks prior to being sent to a sludge storage tank. Following the storage tank, sludge is dewatered with one of two belt filter presses and is then stored in the sludge storage barn prior to land application on Department approved fields.
