purification process like precipitation, absorption and decomposition by increasing the contacting area between water and gravel and oxidation process by the microorganisms stuck on the media. It resolves the pollutant into water and carbon dioxide gas and thus makes the stream water clean. The facility, which has a capacity of 32000t/day, was installed to clean the upstream water to improve the
