The natural quartz sand filter material produced by our factory is made of natural quartz ore as raw material, which is processed by crushing, washing and sieving. The varieties of quartz sand are refined quartz sand, pure white quartz sand, fused quartz sand and ordinary quartz sand, which can meet the needs of different users. Common specifications: 0.5-1.0mm 0.6-1.2mm 1-2mm 2-4mm 4-8mm 8-16mm 16-32mm. Special specifications can be customized according to customer requirements!
　　Classification and application of quartz sand: quartz sand is used as filter material. Quartz sand is combined with filter container to intercept particle impurities such as suspended colloids in water, thus playing a filtering role. It can be divided into the following categories:
　　1. Ordinary quartz sand filter material: It is mainly used in sewage treatment. It is no problem to use quartz sand for three or five years. As long as quartz sand is prevented from losing, it is not important to be polluted because sludge can be aerobically or anaerobically breathed in sewage treatment to degrade pollutants in sewage.
　　2. Refined quartz sand filter material: used in pure water treatment, in the sand filter, usually 2 to 3 years to replace, usually polluted, the contaminant enclosed quartz sand can no longer play a good filtering role, can only be replaced.
　　Refined quartz sand filter material is the most widely used and used filter material in China. It is suitable for single-layer, double-layer fast filter and supporting layer of industrial high purity filter water. The quartz sand filter material produced by our factory is made from natural quartz deposit by mining, crushing, washing and screening (high purity quartz sand is acid washed). Its appearance is white crystalline with polygonal spherical shape. It has no impurities, high mechanical strength, stable chemical performance, large pollution interception capacity, long service life and economic benefits. Good.
