Fujian Zhangzhou Gulei Refining and Chemical Integration Project

Located in the Gulei Peninsula, Zhangzhou, Fujian, the scale is 100000 m³/d. Flocculation, sedimentation, filtration and disinfection processes are adopted for water purification. The specific process is that after the raw water is transported to the water purification plant, flocculants are added through the pipeline mixer on the water inlet pipeline and fully mixed, and then the gravity flow is transported to the clearwell after flocculation, sedimentation and filtration. When the headloss of the filtration reaches a certain degree, the backwashing pumps and fans will be automatically started to backwash the sand in filtration area with air and water. After being treated the effluent meets the qualification of the Standards for Drinking Water Quality (GB5749-2006).
