ZPG automatic backwashing sewage filter

ZPG automatic backwash blowdown filter is a kind of filter that uses low-quality water for industrial cooling, and can also be used for other technological processes requiring filtration. It has the function of flushing and removing impurities. It is generally installed in front of heat exchanger and other actuators to flush and remove impurities regularly. Under normal conditions, the water flows through the impurities on the filter tube wall, and the impurities are discharged from the drain outlet When the diverter valve is closed and the blowdown valve is opened, the water flow is forced to enter the outside of the filter barrel from the mesh at the inlet end of the filter cartridge, and most of the water flows out from the outlet. A part of the water flows from the outside of the filter through the mesh of the impurity collection section to enter the inside of the filter barrel, so as to achieve the small effect of flushing the impurities attached to the mesh from the outside of the filter cylinder, and the impurities still pass through the sewage The water is discharged.
