It's a new polluted water treatment material. The oil removal percentage can reach 95%. It is widely used in oil field, perfication, the water purity treamtment in metallurgy industry. Inrush of oil resistance, never rot, easy to reproduce, can be used whole year, do not need to be changed, has good economic efficiency and enviomental water treatment effect. Has natural hardness, ideal specific weight, more holes and more surfaces, and it has been treated by physical and chemical in speicific way, so it can remove the oil, solidity, and easy to be rewahsed. It is widely used polluted water contained oil, industry wasted water, and civil water.

It can replace quartz sand, and a new product but low price.
