As a major water user, chemical plants typically use millions of cubic meters of fresh water annually, resulting in low water reuse rates. At the same time, they discharge millions of cubic meters of wastewater, which not only wastes a large amount of water resources but also causes environmental pollution. Moreover, the shortage of water resources has posed a threat to the production of these industrial water users. To maintain the sustainable development of the enterprise, reduce water resource waste, reduce production costs, and improve the economic and social benefits of the enterprise. Advanced treatment (tertiary treatment) is required for chemical wastewater as a supplement to circulating water or power desalination water to achieve wastewater reuse. The Sudong programmable automatic filter press can be used for wastewater and sludge dewatering treatment in various industries. It is controlled by a microcomputer controller, PLC, and touch screen, and can perform various operations on the filter press (such as pressing the filter plate, merging and opening the liquid collection plate, loosening the filter plate, opening the filter plate, water flushing, etc.). It also has a remote control interface and can be remotely operated and controlled automatically. Suitable for materials in industries that are prone to dehydration and work efficiently. The most prominent features are compact structure, stable performance, high efficiency, and low operating costs.
