<\/iframe><\/p>\nWorking principle<\/strong><\/p>\nThe liquid flows into the filter from the inlet undera certain pressure, impurities are intercepted by the filtering medium inside the filter, and the filtered liquid flows out from the outlet. When the filtration reaches a certain stage, the pressure difference between the inlet and outlet increases,and backwashing is required. At this time, the backwash valve is opened, and hydraulic pressure flows from the backwash inlet to the backwash from bottom to top, restoring the filtering function of the filter.<\/p>\n<table
