Self-cleaning Water Filter

Automatic cleaning and discharging.

Low maintenance and labor cost.

Filtration precision ranges from 40um to 4000um.

Compact structure with small size.

Various install method for different industries.

Dirty water enters the self-cleaning filter inlet and is directed to the inside of a group of specially designed semi-permanent porous filtration elements. The water passes through the filter elements and out of the self-cleaning filter as Clear Clean Water. Any particulate larger than the filter element pore rating is left trapped inside the filter element. The self-cleaning filter elements are then periodically cleaned when a preset time or differential pressure is reached. When the self-cleaning cycle is initiated, a series of air-operated valves are automatically activated, redirecting a portion of the clean water stream back through the porous filter elements in a reverse flow. The reverse flow flushes the accumulated debris to the back-flush drain and cleans the element. The cycle is repeated until all mechanical filter elements are cleaned and the operating cycle begins again. Less than 1% of the total filter flow is used in the backwash cycle.
