Sludge Dewatering - an overview | ScienceDirect Topics

Sludge Dewatering. The improved sludge dewatering effectiveness was obtained using the energy of ultrasounds of 800 and 2200kJ/kg d.m. An insignificant reduction in the size of sludge flocs and a small increase in the concentration of extracellular polymeric substances (Zhang et al., 2007) can explain the observed improvement in sludge dewatering capacity.

Industrial Dewatering - Evoqua

Sludge dewatering separates sludge into liquid and solid components for waste minimization to achieve overall cost efficiency for disposal. Dewatering is not necessarily intended to treat the sludge or liquid, but instead to separate the solid and liquid components so that it is easier and more cost-effective to handle the separated phases for final disposal.
