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. 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-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
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
Adaptive ecotyping of the toxic cyanobacterium Cylindrospermopsis raciborskii to predict its invasive capacity. We change the world while other organisms adapt to these new conditions. Cyanobacteria (blue green algae) increasingly dominate water bodies that were previously free of these harmful blooms. To minimise the spread of these algae, this project will study the genetic basis that determines how rapidly they can evolve and adapt to a changing planet.
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. 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 uncertai ....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. 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
On-line monitoring of cyanobacteria to predict coagulant doses and powdered activated carbon application in water treatment. Cyanobacteria, more commonly known as blue-green algae, can impact water quality by releasing toxins that can be harmful to human health and imparting unpleasant taste and odours to the water. This project will support the water industry in managing these risks by providing a rapid, on-line tool to assist in their removal during water treatment.
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. It will research the triggers for organic matter excursions that compromise treatment plant performance and affect public health.

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

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
Mitigating the risk of cyanobacterial blooms in wastewater ponds. Cyanobacterial blooms in wastewater treatment plants impact on effluent quality and the utility of recycled water, posing a significant risk to the economy, the environment and public health.

Cyanobacterial blooms in wastewater treatment plants impact on effluent quality and the utility of recycled water, posing a significant risk to the economy, the environment and public health. To understand the causes of cyanobacterial blooms in pond-based wastewater treatment plants and the risk they pose, this project will use the latest molecular techniques to examine how the microbial communities within these systems interact with each other and their surrounding environment to form blooms and produce toxins and other harmful metabolites. Such knowledge will inform risk assessment and provide strategies for the mitigation of future bloom events, improving the security of our increasingly valuable recycled water resources.Read moreRead less

This project seeks to answer the question of how to increase social participation by converting non-volunteers to the benefits of volunteering. In Australia today, communities and governments are increasingly dependent on volunteers to build social capital and deliver an increasing range of services. A world first, this project aims to create new theory by examining three levels of analysis: the micro level of the individual volunteer or non-volunteer; the mezzo level of the volunteer-involving organisation; and the macro level of society. This innovative approach aims to identify, analyse and develop a tool to help organisations build Australia’s civil society and develop policy to create a sustainable volunteer sector into the future.Read moreRead less
