Project of sewage treatment station construction in the produced water collection and treatment system of Fuling Shale G

The project of sewage treatment station construction in the produced water collection and treatment system of Fuling Shale Gas Field is located in Fuling District, Chongqing. The produced water in the field is highly saline with complicated composition and cannot be discharged into surface water bodies directly. Instead, it should be treated through “pretreatment + double-membrane treatment + evaporation and crystallization” process before discharge.

Treatment scale: 1600m³/d + 800m³/d reserved

Treatment process: “DTRO+RO” double membrane process
