Dewatering Screw Press Sludge Treatment Equipment for Water Treatment

The wastewater plant machinery utilizes a multi-disc screw press designed for efficient oily sludge dehydration. The volute dehydrator dewatering drum consists of rings with a variable-pitch auger running through the center. Every second ring is fixed to the barrel assembly and separated by spacers, while intermediary rings are free to move.

The internal diameter of the fixed rings is larger than the diameter of the auger. The intermediary rings have an ID slightly less than the auger and hence are moved in an orbital motion as the auger turns. This movement of the intermediary rings constantly cleans the barrel assembly allowing free drainage of water. This unique arrangement allows for an extremely low power draw and efficient operation.
