A type of self-cleaning filter called an automatic backwash filter has several stainless steel filter elements and can filter continuously for 24 hours.

It can efficiently remove solid particle pollutants from various low-viscosity liquids, including rolling emulsions and water, ensuring that the liquid cleanliness meets system operating and downstream process requirements while also safeguarding important downstream equipment. It is widely utilized in oil and gas, metallurgy, water treatment, pulp and paper, maritime filtration systems, and other industries.

Unfiltered liquid enters the automatic backwash filter from the input, passes through the central distribution tube, moves to the top of the filter, and enters the filter elements from there. The remaining 50% of the liquid does the same.

The remaining portion of the liquid enters the filter’s components directly from the bottom. The unfiltered liquid enters the filter elements simultaneously from the upper and lower ends and exits the outlet after filtering.

The automatic backwash method starts when the pressure decrease or the amount of time reaches the predetermined value. While the filtration process is still going on, the gear motor drives the back-flushing rotating arm to backwash the filter elements one at a time.

The sliding block covers the upper end of the filter element during backwashing, at which point the back-flushing valve opens. The clean filtrate reversely flushes the filter element’s inner surface due to the pressure difference between the filter element’s exterior and back-flushing outlet. The sewage pipe is used to release the contaminants that have been cleaned down.

Brother Filtration designs and manufactures the automatic backwash filter while taking all needs into account. We have inner corrosion paint to resistant the seawater. In addition, multiple types of valves, housing materials, and seal materials can be chosen by customers according to their actual needs.
