Automatic self cleaning brush filter 

Introduction

Automatic brushaway filter is composed of the drive mechanism, the control circuit (including the pressure switch), filter components, cleaning device, connecting flanges and other major component parts.It cleans sewage by the drive motor and the electric valve automatically, the operation mode is automatic operation (option:manual operation), with timing control or pressure difference control. Its automated part is controlled by reliablePLC programmable controller.

Water enters into the filter, the mechanical impurities are intercepted.When the impurities accumulate for a period, reaches 0.05MPa, then the differential pressure switch will send signal, while the PLC command is issued, transmission motor starts, the drain valve opens, the impurities deposited on the filter is brushed away,and drain out.The whole process is without personnel, without downtime. Besides, the device also has the function of timing and manual cleaning to ensure that the outlet water is safe under any circumstances.

Raw water enters the inside of the screen-cylinder from the filter's Inlet and flows through the screen to the filter's Outlet. The dirt particles are trapped on the inner screen surface and formulate a "filtration cake" that causes a differential pressure across the screen.

A pressure differential switch senses the pressure differential and when it reaches the pre-set value, the cleaning process begins.

During the self cleaning process, filtered process water continues to flow. The Drain Valve opens and theMotor rotates the stainless steel brush which sweeps the inner surface of the cylindrical screen. The particles trapped on the screen are dislodged by the brushes and flushed out the drain valve. 

The whole process takes 20-30 seconds.  
During the whole process water supply is uninterrupted.
