The quartz sand filter uses quartz sand as the filtration medium, with the advantages of high filtration efficiency, low resistance, large processing flow, and infrequent backwashing (operational cycles are 1-2 times those of standard filters), capable of fully automatic operation.

It is widely applied in the pretreatment in industries such as pure water, food and beverage water, mineral water, electronics, printing and dyeing, papermaking, and chemical industry, as well as the filtration after secondary treatment of industrial wastewater, reclaimed water reuse systems, and deep filtration of swimming pool circulation water treatment systems.
