Sludge thickening and dewatering

 · 17.4 Sludge Dewatering. Sludge dewatering will often be required at STP prior to ultimate disposal of sludge/biosolids or as a prelude to further treatment or stabilization. Since dewatering processes differ significantly in their ability to reduce the water content of sludges, the ultimate sludge disposal method will generally have a major influence on the dewatering method …
