AWWA QTC97202

The internal corrosion of distribution pipes is one of the major problems faced by utilities. At present, utilities generally select corrosion control strategies through a process of trial and error, often without considering their effects on all the various problems associated with corrosion. To predict the impact of corrosion, as well as the control strategies themselves, pilot studies must be undertaken. Pipe loops, while more representative of flows in distribution systems than other alternatives, are expensive and require large quantities of water. Annular reactors used in biofilm studies may prove to be a useful means for studying corrosion since their outer shell can be fabricated from different materials. The primary objectives of this study were to propose a scientific and realistic approach to the choice of corrosion control strategies for utilities and to develop a pilot-scale experimental approach using annular reactors, which will enable the identification and selection of corrosion control strategies.
