Green Lake, WI, USA
A plant with a Sequencing Batch Reactor (SBR) in Green Lake, Wisconsin was upgraded with an advanced process control system. By controlling the process in a smarter way, the plant experienced improved total nitrogen removal while reducing energy consumption and wear on the blower. In addition, the controller adjusted the process for optimized biological phosphorus removal, resulting in effluent total phosphorus concentrations consistently below 1 mg/l with minimal to no chemical addition.
