Advances in mechanical dewatering of wastewater sludge

N2 Dewatering of wastewater sludge is a difficult process. The difficulty has been attributed mainly to the fact that particles are very fine, colloidal in nature and possess a gel-like structure due to polymeric flocculation. In order to tackle the limitations in wastewater sludge dewatering, new technologies have been developed in recent years.
