Self-cleaning Filter

The suction type self-cleaning filter automatically filters raw water, cleans the filter screen and discharges sewage without manual operation. The cleaning and sewage discharge system provides uninterrupted water supply, and the control mode can be automatic or manual. It is applied in power, reverse osmosis pre-treatment, petrochemical, fine chemical, food and beverage, automotive, industrial, metallurgical, paper, pharmaceutical, microelectronic and environmental water treatment industries, filtering water suspended solids, particles, scale, algae and rust.

Water enters from the inlet and flows into the coarse screen from outside to inside (the coarse screen is set according to water quality). Coarse impurities are filtered out, and then the water enters the fine screen, where smaller impurities are trapped on the inner wall of the fine screen. The filtered clean water flows out from the outlet. During filtration, dirt and impurities accumulate on the inner surface of the fine screen, forming a filter cake layer and creating a pressure difference between the inside and outside of the fine screen.

The backwash cleaning is driven by a motor with suction nozzles. The geared motor drives the suction device and suction nozzle to rotate, and the suction nozzles suck impurities from the inner wall of the fine screen to complete cleaning. The entire operation is controlled by an intelligent control box, with optional control modes: differential pressure, timer, manual or PLC control.

• Fully automatic operation: No manual intervention required for filtration, cleaning and sewage discharge.

• Uninterrupted water supply: Continuous water supply during cleaning and sewage discharge.

• Flexible control modes: Automatic (differential pressure/timer) and manual control options, also supports PLC control.

• Efficient cleaning: Spiral scanning suction design thoroughly cleans the inner surface of the fine screen within tens of seconds.
