- Abstract:
- The diaphragm filter press system utilized for the deep dewatering of municipal sludge is intricate, involving much equipment and requiring meticulous operational control. The initial design plays a crucial role in ensuring smooth system operation. Addressing issues such as prolonged feeding time, low treatment efficiency, and elevated moisture content in the mud cake during the operation, a comprehensive study and analysis are conducted. This examination encompasses design and operational aspects, leveraging insights from the system’s working principles and performance characteristics gathered through field investigations. Key influencing factors including incoming sludge moisture content, sludge conditioning effectiveness, filtration and pressing pressure are thoroughly examined. The study focuses on critical aspects including sludge conditioning, feeding process, and pressing procedure are summarized while recommendations regarding filter press type selection, sludge concentration form determination, conditioning tank design optimization, feed pump selection and installation， pressing system. These proposals are intended to serve as valuable references for the design and operation of similar projects in the future.
