Pottery Granule For Water Treatment
Properties and application of ceramic sand filter
This product has stable chemical properties, including wear resistance, shock resistance, high temperature resistance, corrosion resistance, large specific area, strong filth-stemming ability, good absorbency, uniform grains and proportionate density. Its service lifetime is longer than 15 years, and it does not have the defects of single density, secondary pollution from SiO2 and organic carbon that natural filters have. The product is widely used in single layer or multi-layer pool and machinery filters to treat all kinds of industrial water, domestic water, sewerage, pure water, soft water, industrial dust and boiler fumes.
This ceramic sand filter is composed of anti-corrosive rare earth in the lanthanide and actinide series. It is made of strong corrosion-resistance SiO2.Besides general purpose uses, it can also be used in treatment of boiler water and manufacture of super-pure water.
