Abstract

This method gives a standardized procedure for the conditioning operation when selecting a conditioning product at laboratory scale and also for the production of flocculated thickened sludge for subsequent dewatering tests.

This document provides a method for laboratory chemical conditioning of sludge.

The method applies to sludges and suspensions from:

— storm water handling;

— urban wastewater collecting systems;

— urban wastewater treatment plants;

— industrial wastewater that has been treated similarly to urban wastewater;

— water supply plants.

This document is applicable to all sludge that can have similar environmental or health impacts, or both, with exclusion of hazardous sludge from industry and dredged sludge.
