Our Quartz Sand Filtration, is the natural quartz ore after crushing, screening, and washing .the product is multi-edges, pure white, no impurities, the density 2.66, the silicon content is 99.3%, mechanical strength 7.5 degrees.
At present in some areas people choosing natural river sand and sea sand as filter media, although the cost is inexpensive, the lifetime is short, the mechanical strength is poor, and they are easily crushed.
The lifetime of quartz sand is more 3-4 times than the natural sand’s. what’s more, After filtration the water quality to be stable, on the economic efficiency side, this quartz sand is relatively much more inexpensive than the river sand and the sea sand.
