The wastewater treatment facility (WWTF) currently consists of low and high strength waste equalization tanks, anaerobic conditioning tank, anaerobic digester, anaerobic dissolved air floatation (DAFs) unit, anoxic selector tank, aeration basins, secondary clarification, tertiary filtration with sand filters, post aeration tank, cooling towers, sludge storage tank, and belt filter press for sludge thickening. Chemical addition of ferric chloride and polymer are still added for phosphorus removal and additional sludge thickening and solids removal, respectively. Outfall 009 discharges to an unnamed tributary of the East Twin River and consists of the combination of treated process wastewater, excess polished condensate of whey (COW), retentate from the industrial reverse osmosis (RO) unit, and noncontact cooling water (NCCW). High strength wastewater that was previously segregated and land applied is now treated in the WWTF and discharged as treated process wastewater. The facility still has the option of segregating high strength waste for land application to approved sites and storage facilities via Outfall 002 as necessary. The high strength wastewater could be comprised of whey, whey-by-products, permeate, antibiotic contaminated milk, separator desludge and/or cooker water. Sludge from the WWTF was previously land applied on approved sites via Outfall 004 but is now disposed of at a landfill. The facility still has the option of land applying sludge to approved sites via Outfall 004 if that is deemed necessary. An additional emergency outfall (005) has been retained for land application of untreated process wastewater in the event of an emergency.
