Backwash Self-Cleaning Filter: Specification, Advantage, Application

A backwashing filter is an indispensable treatment method in the process of water purification, which is used to intercept impurities in the water to purify water quality or protect the normal operation of other equipment in the system. 

An automatic backwash filter is an advanced, efficient, and easy-to-operate automatic filter. The filter is composed of a tank body, stainless steel filter screen, sewage part, transmission device, and electrical control part.

Backwash process of automatic self cleaning filter:

1. The reduction motor drives the flushing arm to rotate through the intermediate shaft to align it with the cleaned filter screen;

2. Open the blowdown valve to make the pressure difference between the outside of the cleaned filter screen (clean side) and the blowdown;

3. Under the action of pressure difference, the liquid flow at the cleaning side flows from the outside to the inside of the cleaned filter screen for backwashing, and the pollutants accumulated on the inside of the filter screen are washed away and discharged from the filter through the drain outlet;

4. The backwash time of each filter screen has been set. When the backwash time is reached, the blowdown valve is closed, the backwash process of the filter screen is completed, the reduction motor drives the backwash arm to rotate again, the next filter screen is backwashed, the blowdown valve is opened again, and so on to backwash each filter screen;

5. After all filters are cleaned, the flushing arm returns to the original position under the control of the photoelectric switch, and a backflushing cycle ends;

6. Since backwashing is the flushing process of a group of filter screens, the filter can still maintain the continuous filtering state of liquid flow during backwashing.
