Mud is generally liquid or viscous before it is dewatered, which makes it difficult to be transported or temporarily stored, and is easy to spread and cause pollution. Therefore, the mud must be dewatered, and the dewatered water can be reused or discharged directly, so that the solid mud can be easily transported, the mud transport volume can be reduced, and the dewatered mud can be recycled, thus achieving the purpose of saving resources.


 
In addition, the mud contains lots of solid particles such as sand and gravel. If it is discharged into rivers without being treated, it will pollute the rivers, causing sludge sedimentation in the rivers, and affects the living environment of the nearby residents, so the mud dewatering is imperative.
