Sludge Treatment Project of Wangjiahe River in Yueyang, Hunan

In this project, TDC used diaphragm type plate-and-frame filter presses for mechanical dewatering and stabilization for the first time in China. With this method, contaminated sediment can be dewatered and stabilized quickly and the volume of the remained mud cake, with water content less than 50%, will reduce more than 60% compared with the original dredged sludge. The mud cake can be used beneficially for roadbed, landscaping and house building.
