First selected, crushed, and then sieved twice, it has the characteristics of good appearance luster, spherical shape, high mechanical strength, good compressive performance, stable chemical properties, and does not contain toxic substances. It does not dissolve in acidic, neutral, or alkaline water. In addition, the surface of anthracite particles is rough, with good adsorption capacity, high porosity (>50%), and high pollution capacity. Due to its light weight, the required backwash strength is low, which can save a lot of backwash water and electricity.

Reducing project costs and minimizing land occupation are very effective ways. Used in water quality treatment processes before and after production in chemical, metallurgical, thermoelectric, papermaking, printing and dyeing, food, and other industries.
