Anthracite filter media generally use high-quality anthracite as raw material, which is processed by selection, crushing and screening. The finished product has uniform particles, good gloss, compressive and wear-resistant, high mechanical strength and long service life.
Anthracite filter material in the process of filtering , directly affect the filtration of water quality, so the choice of the filter material must meet the following requirements:
1. High mechanical strength, crushing rate and wear rate should not be higher than 3% (by weight).
2. Stable chemical properties, without toxic and harmful substances. It is insoluble in ordinary acid, alkaline and neutral water.
3. The particle size distribution is reasonable and the specific surface area is good. The appearance of the product is spherical and angular, glossiness is good, and it is screened by mechanical vibration for three times. The gradation accords with the relevant technical indexes.
4. The particle size range is less than the specified minimum diameter, according to the weight is not greater than 3%, greater than the specified upper limit of particle size, not more than 2% by weight.

Anthracite filter material is used for ordinary fast filter tanks for domestic drinking water and industrial production water as well as various types of pools.
The use of anthracite filter material in combination with quartz sand filter material is a better material for double-layer fast filter tank, three-layer filter tank and filter tank currently popularized in my country. An effective way to reduce project cost and reduce floor space, double-layer and triple-layer filters, various sewage filters, all kinds of environmental protection equipment filter device, water purification machinery filter and chemical, metallurgy, thermoelectric, pharmaceutical, paper making, printing and dyeing, food and other production before and after water treatment.
