ZPG Automatic Backwashing Sewage Filter
Product overview
ZPG automatic backwash blowdown filter is a kind of filter which uses low quality water for industrial cooling, and can also be used for other technological processes that need filtration. It has the function of flushing and removing impuritiesIt is installed in front of the heat exchanger and other actuators, and is flushed regularly to remove impurities. Under normal conditions, the steering valve is opened, and the water flows through the impurities on the filter pipe wall, and the impurities are discharged from the drain outletWhen the valve is closed and the blowdown valve is opened, the water flow is forced to enter the outside of the filter cartridge from the mesh at the inlet end of the filter cartridge, and most of the water flows out of the outlet, and a part of the water flows from the outside of the filter through the mesh of the impurity collection section to filterInside the filter barrel, the filter cylinder is backwashed to achieve the effect of flushing the impurities attached to the net from the outside of the filter cylinder, and the impurities are still discharged through the sewage.
