Description

[0002] The water quality needs to be purified in all water-using processes required for production. Filters are used in the water purification process. However, after the filter has been used for a period of time, certain impurities will accumulate inside the filter layer, resulting in a decrease in the filtering effect. When this happens, the filter element is generally replaced directly, but such filter elements need to be replaced more frequently, so the backwash filter was born.
