The anthracite filter media uses high-quality Taixi anthracite raw coal from Ningxia as raw material. It is selected, crushed, and screened twice to form a shiny high mechanical strength, good compression resistance, stable chemical properties, and non-toxic substance, wear-resistant, insoluble in acidic, neutral and alkaline water. In addition, the surface of anthracite particles is rough, has good adsorption capacity, large porosity (252%), and high pollution-containing capacity. Because of its light weight, it requires low backwash intensity, which can save a lot of backwash water and electricity.
