Abstract

Wastewater sludge management is costly and technically challenging, with dewatering being a major bottleneck. Advanced sludge treatment (AST) processes aim to improve dewatering. This paper reviews the role of extracellular polymeric substances (EPS) in sludge dewatering and examines the effects of thermochemical and oxidation methods on EPS degradation and flocculation. Experiments on waste activated sludge show that AST enhances dewaterability by degrading EPS, reducing water retention, and promoting flocculation, leading to fewer fine flocs.
