Quartz sand as the filter material applications, quartz sand combined with the filter container used to retain particles in water and other impurities in colloidal suspensions, and thus play a filter role. Can be divided into the following categories: 

 1. Ordinary quartz sand filter: mainly used in sewage treatment in three to five years with no problem, as long as the line to prevent the loss of quartz sand was polluted does not matter, because the sewage treatment, sludge can be aerobic or anaerobic respiration , the degradation of pollutants in the sewage. 

 2. Fine quartz sand: used in water treatment, in the sand filter, generally 2 to 3 years to be replaced, usually the pollutant surround the quartz sand filter can no longer play a role well can only be replaced. In the neutral and acidic water are stable, but slightly soluble in alkaline water with chemical water treatment SiO2 increment does not exceed 2mg / L. 

 Quartz sand by the unique physical and chemical properties, making it in the aviation, aerospace, electronic, mechanical, and the rapid development of today's IT industry occupies a pivotal position, in particular its intrinsic molecular chain structure, changes of crystal shape and lattice , it has a high temperature, thermal expansion coefficient is small, highly insulated, corrosion resistance, the piezoelectric effect, resonance effect and its unique optical properties, in many high-tech products is playing an increasingly important role. 

 High purity quartz sand is an important industrial mineral raw materials, non-hazardous chemicals, widely used in glass, foundry, ceramics and refractories, smelting ferrosilicon, metallurgical flux, metallurgical, construction, chemical, plastics, rubber, abrasive and other industries.
