OVERVIEW

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;
