Screw Press Machine

Sludge dewatering is the process of separating the solid and liquid components of sludge to reduce its volume and facilitate handling and disposal. A screw press is a common and efficient machine used for this purpose.

How Does it Work?

A screw press consists of a rotating screw enclosed within a cylindrical screen. The sludge is fed into the inlet, where it moves along the screw due to its rotation. As the sludge progresses, the screw applies increasing pressure, forcing the water through the screen while retaining the solids. The dewatered solids are discharged from the outlet as a cake, while the recovered water can be further treated or recycled.
