Introduction - Sludge Management
The recent revisions of the Water Regulator under the AMP 3 determinations have increased pressure on Utility companies and others to improve their sludge management techniques. The efficient and effective handling and disposal of sludge whilst complying with current and future landfill and effluent treatment legislative requirements are essential if companies are to operate profitably. Using the most advanced systems approaches coupled with modern biological and fluid engineering techniques can bring substantial capital and revenue cost savings.

This conference brought together users and suppliers of the leading sludge management processes together with consultants and developers of the new generation of sludge management techniques.

Introduction - Sludge Digester Mixing and Heating Systems
In recent times, considerable attention has been placed on sludge digestion processes. This is driven by the potential impact of forthcoming regulation relating to the "Safe Sludge Matrix". The conference brought together the different proponents in the current debates on digester mixing and heating systems. The objective was to provide an overview of all the major types of digester mixing and heating systems currently available and in use.
