This lesson will briefly describe various thickening and dewatering methods, as well as provide an overview of various stabilisation and conditioning methods for sludge.

The conventional sludge process is usually as follows:

*Possible Process Flow for Sludge Treatment*

Please note, that the sequence can vary depending on the established treatment process and required outcome. For example, conditioning faecal sludge with lime is a simultaneous stabilisation step before dewatering.
