This report was produced for the Urban Water Research Association of Australia, a now discontinued research program.
Report no. UWRAA 100
This report presents information from several studies carried out to inform the policy debate on the role of phosphorus in detergents in the Australian context.
Part A presents a summary of the issues and the different points of view on the contribution of detergents to the phosphorus levels in sewage. It includes an outline of studies to develop a method for measuring polyphosphates directly in sewage.
Part B reports on a trial conducted by Melbourne Water in the town of Whittlesea, where householders were provided with non-phosphorus (NP) detergent and asked to use it for a certain period. Detailed studies of the changes in phosphorus loads into and out of the sewage treatment plant are reported.
Part C presents an annotated bibliography on the topic of phosphorus and detergents.
