Sludge consolidation is used by most wastewater treatment works to reduce the sludge volume and hence lessen the cost of downstream processing and disposal. Traditionally the design of consolidation tanks have not allowed for the wide variations in consolidation properties that can occur, even for the sludges of the same type. This guide describes a new procedure which has been developed for the design and operation of tanks which improves the efficiency of the process. A mathematical model is used to predict the performance of sludge in a consolidation tank and hence optimise the process. 'Guidelines for the Design and Operation of Sewage Sludge Consolidation Tanks' is essential reading for all those involved in the design and operation of sludge treatment tanks.
