Quality rare earth porcelain sand filter manufacturers

Rare earth porcelain sand filter is a high mechanical strength, low wear rate, surface area, porosity, near spherical gray filter, is suitable for the removal of impurities in water colloidal new products, I plant extensively absorb domestic experience in the production of ceramic filter media, and through the guidance of the Institute of ceramic experts, repeated formulation experiment, several adjustments in the production process and the firing temperature, developed a water medium ceramic sand with the advanced level. This filter selection local quality kaolin raw material, blending a certain amount of pore forming agent, a binder, after refining mud, forming, drying, sintering and other processes, particle size is generally in a variety of specifications between 0.5 ~ 32mm, used for mechanical filters, filter media, can reduce the amount of backwash, increasing the contact area and the filter surface area, particularly the expansion of the adsorption area and improve the filter's interception capability, increase water production and water production, by the laboratory of the physical chemical properties are superior to other media, mainly used in electric power, petroleum chemical industry, water supply and drainage of water purification. Rare earth porcelain sand filter physical and chemical properties analysis Analysis Project Test Data Analysis Project Test Data gravity 2.57g / cm3 density Water absorption 1.2% 1.65g / cm3 hardness 7 Broken rate 0.02% SiO2 58-74% wear rate of 0.75% Fe2O3 ≤1 % porosity of 46% Al2O3 ≈23% Advantages: 1) rare earth porcelain sand filter with corrosion, oxidation; chemical stability, filtration resistance, the filtrate was clear, effective, long life and other advantages. 2) for the second cycle of water filtration, filter head loss, long regeneration cycles, regeneration simple and convenient, easy to block, you can achieve the best results. 3) for the chemical treatment of waste water filtration, heavy metal removal rate of 90%, suspended solids removal rate of 100%, 90% turbidity removal. Main purpose: Rare earth porcelain sand filter is widely used in single filter, multi-layer filter, mechanical filters do filter in filter media, deal with a variety of industrial wastewater, industrial water, city water, city sewage, water, soft water, but also as a biological filter treatment of organic waste water. It can also be used to filter dust collector to do deal with a variety of industrial dust filter, boiler soot. Common Specifications: 0.5-1mm 1-2mm 2-4mm 4-8mm 8-16mm 16-32mm
