Introduction of Water Treatment Process in Water Supply Company
1. The raw water enters the distribution well, where large and heavy suspended particles settle. The raw water is equally divided into two parts and enters the sedimentation tank through the pipeline connected with the sedimentation tank. There is an incoming turbidity detector in the water distribution well. 2. The distributed water passes through a tubular mixer before entering the sedimentation tank, where the raw water is added to the coagulant ( PAC solution , the main component AL2O3). After entering the flocculation tank, the raw water passes through 48 layers of grids, and the flow rate is further slowed down. The suspended solids and colloidal impurities contained in the raw water react with the coagulant to produce flocculent sedimentation, and part of the flocculation sediments in the flocculation tank. There is a buffer zone between the flocculation tank and the sedimentation area to stabilize the water flow and slowly enter the sedimentation area. The sedimentation area is...
