Rare earth porcelain sand filter 

 Product description: 
 Rare earth porcelain sand filter is a high mechanical strength, low wear rate, specific surface area, high porosity, close to the spherical gray media, new products suitable for the removal of colloidal impurities in the sewage plant widely absorbed The experience of the domestic production of the ceramic filter and Ceramic Research Institute expert guidance, repeated the formula test, repeatedly adjust the production process and the firing temperature, developed with the advanced level of water treatment media porcelain sand. 
 This filter selected local high-quality kaolin as raw material, blending a certain amount of pore-forming agent, binder, after refining the clay, molding, drying, firing and other processes, particle size generally in a variety of specifications between 0.5 ~ 32mm used for mechanical filters, filter media, can reduce the amount of backwash to increase the contact area and the filter surface area, particularly the expansion of the adsorption area, to improve the sewage interception capacity of the filter to improve water production and water yield, by laboratory tests of various The physical and chemical properties are superior to other media, mainly for electric power, petrochemical, water supply and drainage of water purification.
