Melbourne Water's Eastern Treatment Plant (ETP) is to be upgraded by the end of 2012 through the implementation of advanced tertiary treatment. The current secondary treated effluent at the site will be further treated by a process train comprising pre-ozone, biological media filtration, post-ozone, UV and chlorine. Ozone disinfection of bacteria phages and virus in unfiltered secondary treated wastewater was evaluated through pilot-scale continuous flow experiments. Ozone disinfection has been used to achieve low coliform concentrations in wastewater effluents in both Japan and North America, particularly where chlorine disinfection is undesirable for the receiving environment. However, specific research on ozone dose response and disinfection efficacy in unfiltered wastewater is generally unavailable, particularly at elevated turbidities of up to 25 NTU.

The inactivation of indigenous E. coli, FRNA Coliphage and Somatic Coliphage was measured in unfiltered secondary effluent with turbidity ranging from 2.5 NTU to 30 NTU, and with applied ozone dose ranging from 10 to 15 mg/L, resulting in Ct values of 0.2 to 2.5 mg.min/L.
