Quartz sand is natural quartz ore by crushing, washing, screening, pickling, drying, secondary screening of a water filter; Mainly there are two kinds of quartz sand filter, one is ordinary quartz sand, the other is refined acid-washed sand.
Quartz sand filter: high hardness, good corrosion resistance, high density, high mechanical strength, load capacity line life-cycle characteristics, is the ideal material for chemical water treatment. Quartz sand filter, like water through the gravel into the ground, the suspended matter in the water to block down, mainly for small suspension. Application of quartz sand as filter materials: silica sand is combined with the filter container, used to intercept the water suspended solid particles such as colloidal impurities, which play a role in filtering. Ordinary quartz sand filter medium: mainly used in wastewater treatment, 35 years with no problems, just prevent the loss of sand on the line, pollution does not matter, because sewage treatment, sewage sludge can be aerobic or anaerobic Hu, degradation of pollutants in wastewater. Fine quartz sand filter: used in water treatment, sand filters, General 2-3 to be replaced, often polluted, pollutants covered quartz sand can no longer play a positive role as a filter, only replaced. Neutral and values in the range of acid is stable in water, slightly soluble in alkaline water, chemical water treatment of SiO2 in increments of no more than 2mg/L.
Package and storage: quartz sand for bag packing, each bag weighing 50 kg.
Quartz sand other metals content is not more than the national drinking water standards, should not be stacked together with supporting materials and other media. Quartz sand and other filter should not be stowed away and other hazardous substances contaminated items.
