Description
Technical Field

In the mechanical dehydration process, the filtration medium of the sludge layer is compressed to cause the reduction of the porosity, only the adsorbed water and capillary water on the surface can be removed, and the bound water and interstitial water are difficult to remove, which is an important reason for high water content.

For municipal sludge, the water content of filter cakes dehydrated by a belt filter, a screw-stacking dehydrator and a centrifugal machine is about 75-80%, and the water content of sludge dehydrated by a diaphragm plate-and-frame filter press is about 60%.
