1. Overview of sludge deep dewatering filter press
With the increasing emphasis of various countries on sewage treatment and the continuous construction of urban sewage treatment plants, the output of sludge continues to grow, and the rapid and effective treatment of sludge is urgent. The sludge has the characteristics of high water content, a large number of pathogens and microorganisms and other harmful organisms, and high content of heavy metals and organic matter. If it is not treated before discharge, it will cause secondary pollution to the environment.
Sludge dewatering is the main method of sludge reduction. The reduction effect not only affects the transportation and storage of sludge, but also affects the subsequent treatment and disposal of sludge after dehydration.
2. Features of sludge deep dewatering filter press
In view of the high water content of the sludge cake filtered by traditional filter presses, Sudong has researched and developed a special filter press for deep dewatering of sludge according to the characteristics of the sludge.
This series of filter press adopts imported high-molecular TPE elastomer formula to manufacture high-pressure diaphragm filter plates, and the pressing force can reach 3MPa. By squeezing the filtered mud cake twice, the moisture content of the filter cake can be reduced to about 55%. Under the premise of economy, safety and environmental protection, the centralized disposal and resource utilization of sludge are realized, and the \"reduction, harmlessness, stabilization and resource utilization of sludge\" are realized.

4. Application prospect of sludge deep dewatering filter press
Due to the adoption of advanced diaphragm pressing technology, the water content of the filter cake is significantly reduced. Generally, the water content of the filter cake is50%～58%, The filter cake is hard and lumpy, and does not need to be dried. It can be directly landfilled, incinerated, brick made and used as green fertilizer, etc., which significantly reduces the sludge stacking site, greatly saves transportation costs, and improves land use efficiency. Circular Economy. The water content of the filter cake is significantly reduced, and the water taken away by the filter cake is significantly reduced. The filtered water can be reused as reclaimed water, saving precious water resources. Therefore, the sludge deep dewatering filter press will be widely used in the sludge dewatering industry.
