When used, the garnet filter material can be used not only as the filter medium of water, but also as the anti-skid pavement, exterior wall coating, rubber filler (for example, as the filler of automobile tire conveyor belt, it can increase the wear resistance) of highways and aircraft runways. The garnet filter material is also widely used in optical, electronic, mechanical, instrument and other industries.
Can the garnet filter material be used as the filter material in the filter sand tank for swimming pool sewage treatment?
The answer is yes. Garnet filter material is a high-density water purification material, which is mainly used in sewage treatment filter tank and multi-media filter tank. It has the characteristics of acid resistance, alkali resistance, flushing resistance and excellent filtration effect. The Mohs hardness of magnetite filter material is 5.5~6.5, the Mohs hardness of ilmenite filter material is 5.0~6.0, and the Mohs hardness of RZG garnet filter material is 7.5~8.0. The hardness and wear resistance are better than the former two; At the same time, the garnet filter material is almost insoluble in acid and alkali, and has better acid and alkali corrosion resistance. Therefore, the service life of RZG garnet filter material is significantly longer than that of magnetite filter material and ilmenite filter material. In addition, the shape of garnet filter material particles is usually rhombic 12hedron or tetragonal 38hedral crystal. The polyhedron feature can ensure that more suitable gaps can be generated between different particles than between ordinary round or oval particles of other filter materials, which can play a better filtering effect.
