Quartz sand quartz sand filter is made from natural quartz ore, by crushing, washing, screening, pickling, drying, secondary screening made of a water filter; quartz sand filter used mainly two An ordinary quartz sand, the other is the pickling of refined sand. Quartz sand: a big hardness, good corrosion resistance, high density, high mechanical strength, interception capability, long life cycle characteristics, is an ideal material for chemical water treatment. Play the role of quartz sand filter, like water infiltration into the ground through the gravel, like those suspended solids in the water block down, mainly for those fine suspended solids. Edit this paragraph quartz sand quartz sand as filter material classification applications, quartz sand is combined with the filter container for trapping suspended solids in water colloidal particles of impurities, which play a filtering effect.
