    Wastewater treatment - Wastewater treatment - Dewatering: Digested sewage sludge is usually dewatered before disposal. Dewatered sludge still contains a significant amount of water—often as much as 70 percent—but, even with that moisture content, sludge no longer behaves as a liquid and can be handled as a solid material. Sludge-drying beds provide the simplest method of dewatering.

  • A review on sludge dewatering indices Water

    For dewatering, a relationship between dewatering energy requirement and sludge water content shows that only about 20% of water is easily removed, even for conditioned sludge, but once water content is reduced to below 80%, the dewatering energy demand dramatically increases (Lee Hsu 1994; Chu Lee 1999; Wang et al. 2010). This implies that ...
