1. Sludge dewatering is the requirement of environmental protection policy. Sludge contains a lot of water, which will overflow when transported directly, so it cannot be transported directly over a long distance. Environmental protection policy requires reduction first and then secondary treatment.

2. The need of sludge reduction treatment. Sludge itself contains a lot of water and is pasty, so it is not easy to transport or secondary treatment. Only after the sludge is dehydrated and separated from the mud can the mud cake be transported and treated conveniently, and the water can be reused to save water resources. At present, sludge dewatering mainly adopts the forms of sludge dewatering filter press, sludge dewatering screw stacker and sludge dewatering centrifuge.
