  • 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 ...
