Magnetite filter media is refined from magnetite stone containing 40-50% iron. It is characterized by fast filtration speed, strong dirt intercepting ability and long service life. Appearance: brown granular. High mechanical strength, does not contain toxic and harmful substances. It is a necessary material for three-layer filter media filter pool.
Common specifications: 0.25-0.5mm, 0.5-1.0mm, 0.8-1.6mm, 1.0-2.0mm, 2.0-4.0mm, 2.0-5.0mm, 3.0-6.0mm, 4.0-8.0mm.
Magnetite filter media is suitable for pipe-type large resistance water distribution system, belongs to the heavy filter media, specific gravity 4.5g/cm3, bulk density 2.95g/cm3, Moh’s hardness 7.5-8.5, usually used in conjunction with anthracite filter media and quartz sand filter media, mainly for the improvement of the supporting layer and water distribution system has good applicability, high strength, fast filtration speed (30-40m/h), backwashing is not easy to mix the layer. In addition, it has obvious effect on iron removal, manganese removal and fluorine removal.
It is widely used in the fields of water supply and drainage, metallurgy, electric power, chemical industry, petroleum, environmental protection, light textile, papermaking, tanning and so on. It plays a great role in improving the quality of drinking water, high-purity water purification, industrial sewage treatment and extending the life of water supply equipment.
