Monitoring organic matter in drinking water systems using fluorescence spectroscopy: improved early warning, process optimisation and water quality. Climate change is contributing to elevated organic matter (OM) concentrations in drinking water supplies. If insufficiently treated, OM can lead to unacceptable concentrations of disinfection by-products, considered to be potential carcinogens, as well as taste and odour problems and bacterial re-growth in the distribution system. Currently availabl ....Monitoring organic matter in drinking water systems using fluorescence spectroscopy: improved early warning, process optimisation and water quality. Climate change is contributing to elevated organic matter (OM) concentrations in drinking water supplies. If insufficiently treated, OM can lead to unacceptable concentrations of disinfection by-products, considered to be potential carcinogens, as well as taste and odour problems and bacterial re-growth in the distribution system. Currently available on-line monitoring techniques give limited information regarding the nature of OM; however, fluorescence spectroscopy has shown promise in this regard. Hence, this project aims to provide an on-line monitoring protocol utilising fluorescence to aid utilities in their provision of safe drinking water, thus addressing the National Research Priority goal water – a critical resource.Read moreRead less
Validation and monitoring of advanced oxidation for potable water reuse. This project aims to address an important limitation in the ability to monitor performance of advanced oxidation processes used to treat recycled water for drinking.

This project aims to address an important limitation in the ability to monitor performance of advanced oxidation processes used to treat recycled water for drinking. The project will be conducted using a novel pilot system, designed to facilitate flexible operation and detailed monitoring. Through carefully designed experiments, observed operational parameters will be related to treatment performance for a range of contaminants. An expected outcome is the development of a framework to provide validation of process performance relationships and ongoing performance monitoring for use by water utilities and regulatory agencies that oversee their operations. This highly practical framework for validation and performance monitoring of an advanced water treatment process should result in improved viability of water recycling projects, increased urban water supply security and enhanced protection of public health.Read moreRead less
Adapting catchment monitoring and potable water treatment to climate change. Adapting catchment monitoring and potable water treatment to climate change. This project aims to make the water industry capable of foreseeing and managing adverse raw water organic matter quality from the catchment to the treatment plant.

Adapting catchment monitoring and potable water treatment to climate change. This project aims to make the water industry capable of foreseeing and managing adverse raw water organic matter quality from the catchment to the treatment plant. It will research the triggers for organic matter excursions that compromise treatment plant performance and affect public health. The project will develop and deploy innovative sensors to detect targeted water quality changes at the molecular level in situ and real time, and improve operating strategies for robust and reliable performance of existing treatment plants. This catchment to plant approach is expected to make existing treatment assets more productive and defer additional treatment costs.Read moreRead less

The objective of this project is the discovery of novel methods for the treatment and reuse of water for both industrial and household applications. Improved treatment systems with the potential for water reuse offer significant improvements to our overall water management potential. The first part of the project is designed to focus on the study of hot bubble column evaporators for solute decomposition, sterilisation and the de-watering of heavily contaminated industrial wastewater. The second part would be based on the study of a suitable depth filter medium for the treatment of partially treated household sewage water. This is designed to form part of an on-site household sewage water treatment and reuse system which is currently being developed.Read moreRead less
Characterising nanostructure functionality of conventional and advanced polymeric membranes using electrical impedance spectroscopy. Thin film membranes are an important separation process for industrial and municipal water treatment. This project will benefit Australian cities and industries by creating the tools to help reduce energy consumption associated with fouling of thin film membranes and indentify the next generation of efficient low fouling membranes.

Developing the next generation of materials and optimal transport processes for membrane distillation and crystallisation processes. Membrane distillation and crystallisation allows the use of solar energy or waste heat instead of electricity to purify water, concentrate brines, and generate valuable crystalline products. In this project novel membranes and processes will be developed to improve the productivity and reliability of these technologies.
Innovative hybrid membrane-based pretreatment strategies for remote community groundwater supplies. Innovative membrane-based strategies for the removal of particulate foulants from groundwaters prior to the removal of dissolved constituents via advanced techniques will be investigated in this project, with the goal of developing robust, integrated processes for the supply of potable water to remote communities.
Fate of micropollutants in water recycling: influence of dissolved organic matter. Access to safe drinking water is essential for the economic and social development of Australia.

Access to safe drinking water is essential for the economic and social development of Australia. There is increasing interest in applying advanced water treatment processes, such as membrane filtration or ozonation, to treat secondary effluent to a potable standard. This project promotes improved organic pollutant removal and monitoring during advanced water treatment and will contribute to the National Research Priority goal, water - a critical resource, by providing the increased protection of receiving waters including rivers and seawater. Further, as very few studies consider the role of dissolved organic matter for organic pollutant fate in water reuse internationally, this project will help to advance Australia's position in science.Read moreRead less
