Automatic Backwashing

The water to be treated enters the machine body through the water inlet, and the impurities in the water are deposited on the stainless steel filter screen, resulting in pressure difference. The pressure difference between the inlet and outlet is monitored by the pressure difference switch. When the pressure difference reaches the set value, the electric controller signals the hydraulic control valve and drives the motor to trigger the following actions: the motor drives the brush to rotate and clean the filter element, and at the same time, the control valve is opened to discharge pollutants. The whole cleaning process only needs to last for tens of seconds. When the cleaning is finished, the control valve is closed, and the motor stops rotating, so that the system returns to its initial state and begins to enter the next filtering process.
