Sludge builds up in the sedimentation basin of sewage treatment plants or water purification plants, where sewage and various wastewater are introduced, and a large amount of sludge is also generated in the process of purifying the collected wastewater. The sludge generated in this way is mixed with a flocculant made of a polymer material and then agitated to remove water by a dehydration device. A sludge dewatering device is usually disposed between sludge between two upper and lower filter cloths transported along a predetermined path. The mixture of and flocculant is put in and passed between the rollers to squeeze to squeeze out moisture during transfer.

The dewatered sludge is discharged to the outside, and the filter cloth is circulated and reused along a predetermined path of the dehydration device, and thus, sludge particles remain in the filter cloth, and a washing apparatus for removing the sludge is required.
