Stainless Steel SS304 Sludge Dewatering Screw Filter Press Dehydrator

Product Description

SCREW PRESS DEWATERING MACHINE


Sludge dewatering screw press is a screw press that separates liquids from solids. A screw press can be used in place of a belt press, centrifuge, or filter paper. It is a simple, slow moving device that accomplishes dewatering by continuous gravitational drainage. Screw presses are often used for materials that are difficult to press, for example those that tend to pack together. The screw press squeezes the material against a screen or filter and the liquid is collected through the screen for collection and use.

Advantages
Low operation cost: less than 40% of that of belt filter press, and less than 20% of that of centrifugal dewaterer;
Power saving: less than 5% of that consumed by the centrifugal dewaterer; water saving: less than 0.1% consumed by the belt filter press; and medicine saving: saved by 60%
Small volume: save the investment into dewatering room; non-blocking: the strong opponent against oil and fiber sludge;

Sludge Treatment Process


Multi-disk screw press, also known as MDS dewatering press, is a kind of cutting edge sludge dewatering equipment with non-clogging design and low energy consumption, especially applicable for oily sludge.

Dewatering Principle

The initial section of dewatering drum is the thickening zone, where the solid-liquid separating process takes place and where the filrate will also be discharged.The pitch of the screw and the gaps between the rings decrease at the end of dewatering drum, hence increasing its internal pressure. At the end, the end plate further increases the pressure, so as to discharge dry sludge cake.
