It consists of a screw used in sludge thickening and dewatering processes and a rotating cylindrical drum placed horizontally around this screw. In practice, this drum rotates rapidly, creating centrifugal force and separating the waste sludge from the water it contains.

It is a multi-purpose product that can operate at high capacities. Assembly and labor costs are low. Although automation possibility, continuous operation and compact system are the advantages of developing technology, it also has some disadvantages with its energy consumption and special maintenance requirements.

Usage areas:

• Sludge thickening in wastewater treatment plants
• Sludge dewatering in wastewater treatment plants
