An automated system controls operation of a filtration system. The filtration system includes an aeration tank and a filtration tank. The system includes a pressure sensor, an air pump, a bleed passage, and a pressure control. The pressure sensor measures a pressure in the aeration tank. The air pump and the bleed passage are connected to the aeration tank and are controlled by the pressure control based on the pressure measured in the aeration tank.
