Background and Relevance

An innovative Western Australian trial augments drinking water supplies by reinjecting wastewater (WW) treated by microfiltration, reverse osmosis and UV into Perth's major drinking water aquifer. However, even this high level of treatment does not remove all trace organic chemicals, which is a regulatory and health concern. The aim of the project was to minimise key micropollutants in treated WW to be used for indirect potable reuse and will investigate novel advanced oxidation processes (AOPs) and optimisation of existing WW treatment processes for optimal micropollutant removal.
