Abstract: An upgrading modification of the sludge advanced dewatering system in Jiangkou Sewage Treatment Plant of Taizhou City has been made. The process,sludge concentration + chemical conditioning + high pressure diaphragm filter pressing,can accomplish sludge minimizing and stabilizing treatment effectively,and save 41% of the sludge transportation and disposal costs. The process flow and key design parameters of the project are introduced. In addition,the project investment of the upgrading modification,the implementation effect,direct running costs and economic benefits are further analyzed.

Key words: advanced sludge dewatering, high pressure diaphragm filter press, upgrading modification
