Abstract: Nanoscale additives and methodology for their use during polymer-aided sludge dewatering to increase the dewatering efficiency compared to traditionally used polymer-only dewatering processes. The nanoscale additive increases the percent solids in the dewatered cake compared to polymer-only treatment. When the nanoscale additives are added, the centrifugal force (shear) required to obtain high percent solids can be significantly reduced and the optimum polymer dose required for effective dewatering is also significantly reduced.
