Wastewater treatment - Wastewater treatment - Sludge treatment and disposal: The residue that accumulates in sewage treatment plants is called sludge (or biosolids). Sewage sludge is the solid, semisolid, or slurry residual material that is produced as a by-product of wastewater treatment processes. This residue is commonly classified as primary and secondary sludge.

4.2 Sludge Processing Methods/ Selection Procedures When either evaluating or selecting a dewatering process, the designer must consider both prior treatment processes and subsequent disposal practices. A dewatering process cannot be evaluated without also examining the other processes involved in the overall solids handling system.
1. Introduction. In recent years, sludge treatment and management became a bottleneck in wastewater treatment plants (WWTPs) due to the high costs for sludge disposal and the environmental impact resulting from inappropriate dumping (Yang et al., 2015).Therefore, sludge dewatering is required before disposal …
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.
