Centrifugal sludge dewatering | Sludge Processing

Dewatering demands more energy than thickening since more water must be removed to achieve the higher solids concentrations. The dewatered product, whose dry solids (DS) content may be as high as 50%, takes the form of a cake : a deformable semi-solid which forms lumps rather than a free-flowing fluid.

A semi-empirical equation describing the dynamics of the dewatering process is then proposed and calibrated. This equation forms the basis for the technical and eco- nomical optimization of the resting time in terms of required surface area and drying efficiency. An optimum of 11 days resting time was finally evaluated in the presented case study.
