The basic characteristics of quartz sand:
Using natural quartz ore by crushing, screening, washing and other processing. Appearance of multi-prism, sphere, pure white, with high mechanical strength, interception capability, acid and good performance characteristics.
Quartz sand filter is made from natural quartz ore, crushing, washing, screening, pickling, drying, secondary screening of a water treatment filter; common quartz sand there are two, one is ordinary quartz sand, the other is refined sand pickling quartz sand with: hardness, good corrosion resistance, high density, high mechanical strength, load capacity sewage lines long life cycle characteristics, is ideal for chemical water treatment materials.

| Detailed description |
Quartz sand act as a filter, like the penetration of water through the gravel into the ground, like those of the suspended matter in water block down, mainly for those fine suspended solids.
Quartz sand as filter material applications: quartz sand is combined with the filter container for trapping suspended solids in water mixed colloidal particles, which act as a filter.
Ordinary quartz sand: mainly used in sewage treatment, three to five years with no problem, as long as the line to prevent the loss of quartz sand, is polluted does not matter, because the sewage treatment, sludge can be aerobic or anaerobic respiration, the degradation of pollutants in sewage.
Refined quartz sand: used in water treatment, in the sand filter, generally two to three years to be replaced, usually the pollutant wrap quartz sand filter can no longer play a good role, and only can be replaced. Quartz sand through so9001-2000 quality system certification.
Value in the neutral and acidic water in the range are stable, but there is slightly soluble in alkaline water, chemical water treatment SiO2 increment does not exceed 2mg / L.
Packaging and storage:
Quartz sand is woven bag, net weight 50 kg. Quartz sand with supporting materials and other media should not be stacked together. Quartz sand and other media not with other toxic and hazardous materials stacked together of contaminated items.
Ministry of Construction quartz sand ministerial standards:
Natural quartz deposits as raw materials, mining, crushing, washing, screening and other processed (high-purity quartz sand pickling), high mechanical strength, chemical stability meet the Ministry of Construction (CJ/T43-1999) standards.
