- Principle of Drum Thickening-Dewatering Belt Filter Press After the sludge and polymer injected are mixed evenly in the conditioning tank, floc granules are formed and flow into a drum for sludge-water separation. The conditioned sludge is sent to the fine screen of the separation drum of our drum thickening-dewatering belt filter press. Then, it is slowly rotated by a centrifugal screening machine, so as to remove a large amount of supernatant free water by filtration. In this way, the sludge is effectively thickened.

- Principle of Gravity Belt Thickening-Dewatering Belt Filter Press The slurry and polymer are firstly injected into the conditioning tank for uniform agitation. The mixture will become solid particles that can be easily dehydrated, and then flow into the filter screen for sludge-water separation. The conditioning tank of our belt filter press is constructed from stainless steel.
