Anthracite Filter Media：
Anthracite filter media is a filter for water treatment that can be used for the treatment of common acids and moderate alkalis. The surface area of the product is large, and all indicators exceed the construction water standards. Anthracite filter media is especially selected from deep well minerals, so it contains the highest percentage of carbon. The reapplied material is often washed and washed to ensure that the product has a good effect on water filtration.
NATURE Anthracite filter is made by high quality Anthracite coal, through the selection, powder and screen process, it has good shape, high hardness, anti-pressing and wearing, does not dissolve in acidic, alkaline, neutral water ,and it is popular used in various water treatment.

Anthracite coal is widely used as the best water filter material, and it is a common form of double layer filter and three layer filter tank, which is widely used in the world. it is the most effective way to increase the filtration rate, increase theamount of water output per unit and increase the interception capacity, reduce the cost of project even the occupation area. Anthracite coal also widely used in water treatment of chemical, metallurgical, thermoelectric, pharmaceutical, paper making, printing and dyeing, food, etc.
