Ceramic filter, porcelain sand filter particle filter departments, made ​​of high quality clay, add a pore-forming agent, sticky solvent, milling, screening, molding, and calcined. With a hard surface, internal microporous, large surface area, high porosity characteristics, under the same conditions, the ceramic filter than the quartz sand filter water production increased several times over, recoil water consumption saving me than the quartz sand 35-50%, but the the filter fast regeneration cycle length can be used to dry slow sand filtration, rapid sand filter, single filter or multilayer filter filter, used for city water, industrial water, sewage treatment, can also be used for microbiological carrier, composed of the biofilter, the removal of organic compounds in water ammonia, nitrite, 16 kinds of biological filter material ideal.
