The main body of Song Dynasty is black particles. Anthracite filter material is divided into refined anthracite filter material and ordinary anthracite filter material. Refined anthracite filter material is high-quality fragrant carbon selected from the two major coalfield deposits in Yangcheng and Jincheng, Shanxi. Raw materials, with very high carbon content percentages. c=..> Song Dynasty& & &>Ordinary anthracite has a slightly higher carbon content than refined anthracite, so its effect on water purification is not as good as ordinary anthracite. The anthracite filter material produced by our company is refined anthracite filter material, which is processed by artificial selection, crushing, screening and other processes. Refined anthracite has uniform particles, good gloss, resistance to pressure and wear, high mechanical strength, and long service life. It is suitable for purifying drinking water and is an indispensable water purification material in double-layer and three-layer filters. Various technical indicators All meet and exceed the standards of the Ministry of Construction (
