ZK SEPARATION Decanters for Sludge Dewatering Processing
ZK sludge centrifuge is professional industrial separation equipment for sludge dehydration treatment. The central part is composed of a cylindrical bowl. When the equipment is working, the bowl rotates at high speed to separate the wastewater liquid from the solid and discharge the liquid and solid substances separately through the discharge port. The equipment has an automatic control system and can work continuously without interruption. Which can significantly improve the efficiency of sludge treatment.
