Common Problems and Performance Improvement of Old Clarifier

Li Wen-jie，Ye Ming-jun，Sheng Li

[Abstract]Clarification tank is widely used in raw water pretreatment system of power generation enterprises. After long-term use，there are various problems in operation that affect the treatment of water quality. Based on the analysis of the problems，the projects of improving clarifiers were put forward. Practice has proved that the technical transformation of the old clarifier can increase the running water quantity and improve the effluent quality. The project investment is cut down，and additional occupation are not needed，as well as the construction period of the project is shortened by the solutions.
