In 2009, based on the existing two sewage stations, Fuji-ta Group demolished and built the advanced sewage stations with new local standards. Specific implementations were:
I. Based on the existing sewage stations, the company built a set of preliminary sewage treatment facilities, subsequent MBR membrane modules which could stably reduce the COD content in sewage and other related treatment facilities.
II. After transformation, the underground sewage pipe network and newly-built recycled water pipe network could use recycled water as much as possible, so as to save water resources.
The above two transformations can increase the COD standard from the original 150mg/l to 60mg/l, achieve the sewage treatment capacity of 80m³/H, reduce the COD emissions to 26.01 tons/year, and enhance other indicators. The sewage station project can realize the multi-level reuse of water. These treatments reflect the social responsibility of Fuji-ta Group, conserving the water resources and making a contribution to social environmental protection.
