It describes the use of variable speed submersible pumps controlled manually, by influent flow percentage, or set flow rate, with flow measured by specific meters. The strategy includes operational configurations for aeration basins and secondary clarifiers, operator controls at field locations and electrical rooms, and SCADA/PLC integration for pump control and monitoring.
