(1)Product overview Rare earth porcelain sand filter is a high mechanical strength, low wear rate, large specific surface area, high porosity, close to the ball of gray filter, is suitable for the removal of colloidal impurities in water of new products, I plant extensively absorb domestic ceramic filter production experience, and through the Ceramic Research Institute expert guidance, repeated test of formula, repeatedly adjust the production process and sintering temperature, developed with the advanced level of water treatment medium porcelain sand. This type of filter media selection of local quality kaolin as raw material, mixing an amount of pore-forming agent, binder, through mud refining, molding, drying, sintering process, particle size is usually 0.5 ~ 32mm between the various specifications, for mechanical filter, filter medium, can reduce the amount of backwashing, increase the contact area and the filter sheet area, especially to expand the absorption area, improve the filter sewage capacity, increase the water yield and water, testing of various physical and chemical properties are better than other media, mainly used in electric power, petroleum chemical industry, water supply and drainage water purification treatment. (2)Physical, chemical properties analysis
(3) product advantages: A rare earth porcelain sand filter has the corrosion resistance, oxidation resistance; chemical stability, low filter resistance, clean filtrate, good effect, long life etc.. B was used for the two cycle of water treatment filter, filter water head loss is small, long regeneration period, regeneration is simple and convenient, it is not easy to be blocked, can achieve the best benefits. C for the chemical treatment of waste water filtration, heavy metal removal rate above 90%, suspended solids removal rate of 100%, the removal rate of turbidity 90%. (4) the main purpose: Rare earth porcelain sand filter is widely used in the monolayer, multilayer filter filter, mechanical filter for filtering as a filtering medium, all kinds of industrial wastewater treatment, industrial water, city water, city sewage, water, soft water, but also can be used as biological filter material in treatment of organic wastewater. Can also be used to filter filter processing various industrial dust, soot. Commonly used specifications: 0.5-1mm 1-2mm 2-4mm 4-8mm 8-16mm 16-32mm |
