Advancing water pollution emissions modelling in cities of the future. This project aims to advance stormwater pollution modelling and enhance its link with urban development. Management of stormwater pollution by industry often results in inadequate strategies and, crucially, sub-optimal financial investments. Since this is unlikely to improve in light of urban growth and climate change, addressing decade-old pollution modelling knowledge gaps and the lack of a multidisciplinary approach to stormwater pollution management is urgent. The anticipated outcome is a modelling tool which industry can use to manage stormwater pollution in changing cities through smarter and economic technology and policy.Read moreRead less
Sources, sinks and processes of faecal contamination in urban estuaries: a case study of the lower Yarra River estuary. The Yarra River estuary is highly contaminated with faecal pollution, reducing the useability of Melbourne’s most iconic feature. This project will provide the necessary understanding to help mitigate faecal sources, with the ultimate aim of reducing the risks to users of this estuary.
Ammonia recovery from wastewaters using flow electrode-membrane systems. This project aims to develop an innovative approach to the recovery of ammonia from dilute wastewaters using coupled-flow electrode-membrane technologies that also enable energy recovery. The outcome of the project is expected to minimise damage to, and develop solutions for, restoration and remediation of, soil, fresh and potable water, urban catchments and marine systems, and significantly improve the environmental impact ....Ammonia recovery from wastewaters using flow electrode-membrane systems.

The effect of wastewater treatment on the ecotoxicity of chiral chemicals. This project aims to assess the environmental implications of pharmaceuticals discharged in effluents from wastewater treatment plants. Trace levels of human pharmaceuticals occur in sewage and urban waterways, but during sewage treatment, some pharmaceuticals can undergo a chemical transformation known as 'chiral inversion'. In some cases, this may convert relatively benign environmental contaminants to more ecologically ....The effect of wastewater treatment on the ecotoxicity of chiral chemicals. This project aims to assess the environmental implications of pharmaceuticals discharged in effluents from wastewater treatment plants. Trace levels of human pharmaceuticals occur in sewage and urban waterways, but during sewage treatment, some pharmaceuticals can undergo a chemical transformation known as 'chiral inversion'. In some cases, this may convert relatively benign environmental contaminants to more ecologically toxic species. This project will investigate why and how some pharmaceuticals become susceptible to chiral inversion and assess ecotoxicological differences. This work is expected to determine the significance of considering chiral inversion in environmental risk assessment, with applications to a broader range of chemicals including pesticides and industrial chemicals.Read moreRead less
Development and Modellling of Advanced Coagulation and Oxidation Processes. The success of this program will help place Australia at the forefront of water quality control and management research. It will address concerns with managing and treating waters of changing characteristics due to climate change. In addition to the socio benefits, project success will also impart economic benefits to the nation through (i) fabricating new hybrid coagulants, that are versatile with enhanced performance ....Development and Modellling of Advanced Coagulation and Oxidation Processes.

It will address concerns with managing and treating waters of changing characteristics due to climate change. In addition to the socio benefits, project success will also impart economic benefits to the nation through (i) fabricating new hybrid coagulants, that are versatile with enhanced performance for removing NOM, and possess antimicrobial properties (ii) developing a new energy efficient photocatalysis technology.The proposed research will expand the knowledge base in this area and increase Australia’s international profile as a global leader in developing cutting-edge cost effective water resource technologies.Read moreRead less
From hazard identification to risk management. From hazard identification to risk management. This project aims to explore health risks from water- and sediment-borne bacteria to recreational users of urban rivers, using a suite of novel molecular microbiological and in-vitro assays and microbial risk assessment modelling. This project also aims to develop source tracking methods to mitigate and manage these risks.

This project aims to explore health risks from water- and sediment-borne bacteria to recreational users of urban rivers, using a suite of novel molecular microbiological and in-vitro assays and microbial risk assessment modelling. This project also aims to develop source tracking methods to mitigate and manage these risks. The number of bacterial-related water-borne outbreaks associated with recreational activities is rising, but waterway managers are under pressure to re-open these rivers for recreation. The project is expected to benefit urban communities by ensuring waterway managers make informed decisions about river recreation.Read moreRead less
Optimising CDI Water Treatment for Ion Removal and Energy Recovery. This project aims to develop capacitive deionisation (CDI) for the decontamination of water. The specific goals are firstly to identify applications where CDI could cost-effectively make brackish, contaminated water usable. The project then intends to optimise CDI design and operating conditions to remove particular ions of concern and to develop approaches to energy recovery. The main outcome is intended to be a photovoltaic-po ....Optimising CDI Water Treatment for Ion Removal and Energy Recovery.

The specific goals are firstly to identify applications where CDI could cost-effectively make brackish, contaminated water usable. The project then intends to optimise CDI design and operating conditions to remove particular ions of concern and to develop approaches to energy recovery. The main outcome is intended to be a photovoltaic-powered CDI unit that is capable of stand-alone operation with optimal energy recovery and inbuilt monitoring, and control technology enabling cost-effective and sustainable operation.Read moreRead less
A new end use of recycled water for sustainable Australian water. The economic, environmental and social impacts of this project would have benefits across Australia, and the rest of the world. Recycled water has never been used in clothes washing machines anywhere in the world, by introducing it here in Australia we would save approximately 20% of domestic water used for laundry purposes. This also has significant policy implications as this would be a huge step towards the implementation of a ....A new end use of recycled water for sustainable Australian water.

High performance multifunctional hierarchical structured membrane for water processing. The water processing industry is one of the most important economic sectors in Australia, though water scarcity is an economic limiting growth factor. The project targets at developing the next generation water processing technology affordable to residential consumption and applications in the industry and agriculture.
Smart management of disinfectant in chloraminated water-supply systems. Smart management of disinfectant in chloraminated water-supply systems. This project aims to develop an adaptive, real-time control system for managing disinfectant residuals in chloraminated water supply systems.

Smart management of disinfectant in chloraminated water-supply systems. This project aims to develop an adaptive, real-time control system for managing disinfectant residuals in chloraminated water supply systems. While chloramine delivers microbiologically safe drinking water in warmer climates and in long distribution systems, it is largely unpredictable, costs water utilities millions of dollars annually, and has uncertain benefits. This project’s control system will be guided by quantitative models formulated from multi-pronged, fundamental experiments. The project will quantify microbial chloramine decay and determine mechanisms to increase predictability. The project will develop and demonstrate a real-time control technology which delivered microbiologically safe, cost-efficient drinking water to people in warmer climates, despite warming climate and increasing population.Read moreRead less
