Abstract
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.
Claims6
A system for controlling operation of a water filtration system having an aeration tank and a filtration tank, the system comprising:
- a pressure sensor for measuring a pressure in the aeration tank;
- an air pump connected to the aeration tank;
- a valve for opening and closing a bleed passage connected to the aeration tank;
- and
- a pressure control for controlling the air pump and the bleed passage based on the pressure measured in the aeration tank, wherein the pressure control activates the air pump to supply air to the aeration tank and activates the valve to open the bleed passage when the pressure in the aeration tank reaches a minimum pressure level so that the pressure in the aeration tank steadily increases, and the pressure control deactivates the air pump to discontinue supplying air to the aeration tank and deactivates the valve to close the bleed passage when the pressure in the aeration tank reaches a maximum pressure level.

- an air pump connected to the aeration tank;
- a valve for opening and closing a bleed passage connected to the aeration tank;
- and
- a pressure control for controlling the air pump and the bleed passage based on the pressure measured in the aeration tank, wherein the pressure control activates the air pump to supply air to the aeration tank when the pressure in the aeration tank falls below a first pressure level, the pressure control activates the valve to open the bleed passage when the pressure in the aeration tank falls below a second pressure level so that the pressure in the aeration tank steadily increases, the pressure control deactivates the valve to close the bleed passage when the pressure in the aeration tank exceeds a third pressure level, and the pressure control deactivates the air pump to discontinue supplying air to the aeration tank when the pressure in the aeration tank exceeds a fourth pressure level.
