Quartz sand filter
Ⅰ、Product overview
Quartz sand filtration is one of the most effective methods to remove suspended solids in water. As the pretreatment of water treatment equipment, he mainly through the filter material of sediment, colloid, metal ions and organic matter to intercept, adsorption and removal of suspended solids in water, sediment, rust, colloid, commonly used in purifying water treatment and wastewater treatment, because of its no pollution, low prices, low running cost, so the application of more extensive, common filters are of 304 stainless steel material, carbon steel material, generally using epoxy or internal rubber lining anticorrosive processing, cloth cloth water common trumpet the toast water on water system, water hanging basket cloth, cloth under water has a flat cloth, cloth water dome board, stainless steel water tube type cloth, Cloth water cap has ABS mushroom head and stainless steel cylindrical silk water cap cloth water, because to take into account the quartz sand filter backwash, so the general water distributor flux is usually three times the running flow.
Ⅱ、The working principle of
Quartz sand filter uses quartz sand as filter medium. The filter material has the advantages of high strength, long life, large treatment flow, stable and reliable effluent quality, etc. The use of water pump pressure, so that the raw water through the filter medium, remove suspended matter in the water, so as to achieve the purpose of filtration.
Ⅲ、Technical characteristics
1、Unique multi-filtration chamber structure enables online backwash (simultaneous filtration, blowdown and backwash).
2、According to the water pressure of the system, the tank material can choose to use carbon steel, stainless steel, fiberglass.
