porcelain sand filter material

The company had developed the SH-1 model porcelain sand filter and SH-2 model rare earth porcelain sand filter with the world advance level through about ten years. Referring to the foreign and domestic manufacture experience of the ceramic filter and under the guidance of Tong Ji university Hu Nan university Hu Nan electric research institute Zhong Nan supporting-outgoing water research design institute experts. SH-1 model porcelain sand characteristic and purpose: Stable chemical property, high strength, enduring crush, anti-corrosion, enduring high temperature, large specific surface, strong pollutant entrapping capacity, good absorption, even particle size, long life up to 15 years. This dissolved the nature filter weakness, unchangeable density, producing SiO2 and organic carbon in the abrasion, making second pollution. Widely used in the single,multi,No-valve mechanical filter, as a filtering medium, it cam threat deferent industry waste water,industry supporting water,civil running water,civil sewerage purifying water,softening water etc. It can also be used in the filtering dust equipment to deal with the industry dust and boiler’s flue dust. SH-2 model rare earth porcelain sand, adding to the SH-1 property, has the stronger anti-corrosion,SiO2 more stable, because added some anti-corrosion rare earth elements, such as lanthanum series and actinium series, specially for the boiler water treatment and super-purification water manufacture.
