Elaborates good practice for sludge dewatering and belongs to a series on sludge management options. Provides guidance on technical and operational aspects of conditioning, thickening and dewatering processes.

This Technical Report describes good practice for sludge dewatering and belongs to a series on sludge management options.

It gives guidance on technical and operational aspects of conditioning, thickening and dewatering processes.

Drying, which is another water content reduction process, is not dealt with in this document, but in CEN/TR 15473, Characterization of sludges — Good practice for sludges drying.

This report is applicable for sludges from:

• urban wastewater treatment plants;

• treatment plants for industrial wastewater similar to urban wastewater;

• water supply treatment plants.

This document may be applicable to sludges of other origin.
