Pilot study for Melbourne Water

During this pilot ozone combined with ceramic membranes to treat secondary effluent was evaluated at Eastern Treatment Plant (ETP), Melbourne. The overall objective of this project, funded primarily by the Australian Water Recycling Centre of Excellence, was to demonstrate the performance and cost benefits of ceramic membranes to treat water containing high organic matter typical of secondary effluent. This work was performed in 2012 and 2013 and the results supported the performance benefits proposed by ceramic membranes in conjunction with ozone. High fluxes, and/or reduced chemical usage and enhanced total disinfection are unique features which would have benefits to waste water recycling. A costing study was completed by late 2013 to quantify these benefits for water recycling in Australia leading ultimately to the follow up at WaterCorp.
