Sludge dehydrator descriptions

The rotation of the screw shaft produces a great internal pressure under the blocking action of the backpressure plate while pushing the sludge transportation so that the volume is continuously reduced, and the purpose of dewatering is finally achieved.

Sludge dehydrator process

The sludge is delivered to the metering tank through the sludge pump, and then the sludge flows into the flocculation mixing tank. The excess sludge flows back to the sludge tank from the overflow pipe. Inject polymer flocculants into the flocculation mixing tank, alum floc formed after stirring, and then enters into a dewatering section of a screw press after gravity concentration (pre-treatment) section. Flocculation and dewatering are carried out in sequence, so that we have a three-stage separation process: flocculation, dewatering and concentrate recovery.

Sludge dehydrator key features

This series of screw press machines are suitable for the pressing and dewatering of solid materials like sludge and other solids, such as some waste food materials and other industrial wastes.

The main body of the sludge dewatering machine can be divided into two parts: in the first part where gravity concentration occurs, the screw will rotate downward and push out a mixture of water and solid materials that are below it.

In the second part where there is no gravity concentration, but with pressure generated by the rotating screw, pressure is applied to keep the solid materials pressed between rings so that they can get dehydrated by moisture vaporization during operation.
