The ammonia loading model-based feed-forward aeration control system outlined herein shows more robust process disturbance rejection than traditional PI control methods, resulting in overall improved process efficiency and decreased mean time deviation from DO set point. Control methods are discussed and verified through simulation and practical application at Poinciana Water Reclamation Facility No. 2 located in Polk County, Florida.
