Anthracite Filter Media for Water Treatment
Product Description |
The Anthracite Filter Media for Water Treatment uses high quality raw coal as raw material, which is selected, crushed and sieved twice. It comes with good gloss, spherical shape, high mechanical strength, good compression resistance and stable chemical properties. Besides, it contains no toxic substances, is resistant to abrasion, and does not dissolve in acidic, neutral and alkaline water. The Anthracite Filter Media for Water Treatment also has a rough surface, features good adsorption capacity, large porosity (≥52%), and high pollution capacity. Due to its light weight, the required backwash intensity is low, which can save a lot of backwash water and electricity. It is widely used in water treatment processes before and after production in chemical, metallurgical, thermoelectric, pharmaceutical, paper, printing and dyeing, food and other industries.
