Sludge dewatering is a wastewater treatment process that uses dedicated separation equipment to separate liquid and solids. During sludge dewatering significant mechanical forces are applied that help release water from the sludge. The concentrated solids are discharged as sludge cake, typically in the 15-30% TS range. Polymer may be added during the process to optimize the mechanical separation. Sludge dewatering usually follows some form of sludge thickening treatment.
