The specific application of quartz sand filter material as filter material: Refined quartz sand filter material is an extremely widely used filter material in my country. The material is made from natural quartz ore after crushing, screening and washing. It has a polygonal shape, pure white color, no impurities, a density of r, >.

At present, natural river sand and sea sand are used as filter materials in some areas. Although the cost is low, the service life is short and the mechanical strength is poor. , easily broken. The service life of quartz sand is r, >
times longer than that of natural sand. Moreover, the water quality after filtration is stable. From the perspective of economic benefits, relatively speaking, this quartz sand is much cheaper than river sand and sea sand. Domestic quartz sand filter media has reached the world's leading level.
