Quartz sand filter is made from natural quartz ore, by crushing, washing, screening, pickling, drying, secondary screening made of a water filter; common quartz sand there are two, one is ordinary quartz sand, and the other is the pickling of refined sand.
Quartz sand: a big hardness, good corrosion resistance, high density, high mechanical strength, long lines carrying sewage capacity cycle characteristics, it is an ideal material for the chemical treatment of quartz sand filtration to play like. water infiltration into the ground through the gravel as those suspended matter in the water block down, mainly for those fine suspended solids quartz sand as filter material application: quartz sand is combined with the filter container for trapping colloidal suspension in water and other particulate impurities, which play the role of ordinary quartz sand filter: mainly used in sewage treatment, three to five years with no problem, as long as the quartz sand to prevent the loss of the line, is contaminated does not matter, because the sewage treatment sludge can be aerobic or anaerobic Hu suction, the degradation of pollutants in sewage refining quartz sand filter: used in water treatment, the sand filter, generally two to three years to be replaced, usually after being contaminated, Pollutants wrap quartz sand filter can no longer play a good role, and can only be replaced at neutral and acidic water value in the range of very stable, but there is little dissolved in alkaline water, chemical water treatment SiO2 increments of not more than 2mg / L.
Packaging and storage: quartz sand filter is woven bag weighing 50 kg.
Quartz sand other metal content does not exceed the national drinking water standards, should not be stacked together with supporting materials and other media. Quartz sand and other media should not be stacked with other hazardous materials polluting goods.
