Features: 
 Rare earth porcelain sand filter of porous ceramic materials by adding rare earth raw materials refined from the company production of porcelain sand filter has a very strong adsorption capacity, high strength, low resistance, corrosion resistance, non-toxic, renewable simple, long life and so on. Traditional quartz sand, granite, anthracite and other low porosity filter material than the surface area, pollutant poor, low yield, water quality unstable. Filtration cycle and short life, difficult to meet the various components of complex industrial wastewater treatment and pollution increasingly aggravated domestic water, industrial water depth of processing requirements. Shortcomings of traditional media and new media developed under the foreign experience, the use of high-quality kaolin, binder, pore forming agent, rare earth resist, the appearance of high temperature firing into a white, hard, uniform particles, micro- hole developed, porosity, plump roundness of new media - Rare porcelain sand filter. 
 Porcelain sand filter has stable chemical properties, abrasion resistance, impact resistance, corrosion resistance, high temperature, large specific surface area, pollutant entrapment, adsorption performance, uniform particles, the proportion of appropriate life of up to 15 years. Rare earth porcelain sand filter with the addition of a corrosion-resistant gold lanthanide and actinide rare earth elements, in addition to a general type of porcelain performance, go further enhance corrosion resistance, SiO2 more stable. 
 Advantages: 
 1) porcelain sand filter has a corrosion-resistant, anti-oxidation; chemical stability, resistance and filtration, the filtrate was clear, effective, and long life. 
 2) for the second cycle of water treatment filters, filter head loss, regeneration cycle is long, renewable simple and convenient, easy to block, can achieve the best results. 
 3) for the chemical treatment of waste water filtration, heavy metal removal rate of 90%, 100% removal of suspended solids, turbidity removal efficiency of 90%. 
 Main purposes: 
 Rare earth porcelain sand filter is widely used in single-layer filter, multi-layer filter, mechanical filter to filter in the filter media to do to deal with all kinds of industrial waste water, industrial water, city water, city sewage, water, soft water, but also can be used as bio-filter treatment of organic wastewater. Can also be used to filter dust collector to do deal with all kinds of industrial dust filter, boiler soot.
