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.
Portable and field-deployable analytical platforms for water monitoring. This project sets out to tackle one of the costliest and most challenging environmental problems, namely, nutrient pollution in water systems. At present, nutrient pollutant monitoring is predominantly carried out using an antiquated manual approach with numerous shortcomings, inadequate to achieve truly effective water quality management. The in-situ analyser developed and deployed within this project will provide continuo ....Portable and field-deployable analytical platforms for water monitoring. This project sets out to tackle one of the costliest and most challenging environmental problems, namely, nutrient pollution in water systems. At present, nutrient pollutant monitoring is predominantly carried out using an antiquated manual approach with numerous shortcomings, inadequate to achieve truly effective water quality management. The in-situ analyser developed and deployed within this project will provide continuous real-time observations and will allow users to remotely monitor water quality; alerting them to pollutant levels, enabling immediate action to be taken to prevent environmental damage. The system is low-cost, facilitating mass adoption, yet delivers an analytical performance comparable to leading laboratory analysers. Read moreRead less
Passive biofiltration processes for nitrogen removal from polluted waters. Traditional urban wastewater treatment is energy and resource demanding. By combining principles of Water Sensitive Urban Design (WSUD) with advanced pollutant removal processes, we will create necessary knowledge to underpin development of novel sustainable urban water treatment systems.

Traditional urban wastewater treatment is energy and resource demanding. By combining principles of Water Sensitive Urban Design (WSUD) with advanced pollutant removal processes, we will create necessary knowledge to underpin development of novel sustainable urban water treatment systems. This project aims to understand and utilise Simultaneous Nitrification, Anammox and Denitrification (SNAD) processes within passive plant-soil-based biofilters for cost-effective removal of nitrogen from a range of polluted urban water sources. The project will open a potential for a new technological advancements in urban water management, while simultaneously providing benefits to the environment and community through greening and waterway protection.Read moreRead less
Advanced water treatment technologies to minimise nitrogenous disinfection by-products in drinking water: understanding the role of organic nitrogen. This project will identify improved methods for treatment of drinking water to prevent the formation of potentially hazardous disinfection by-products. It will assist water resource managers and regulators to select the most economical and safe treatment for each type of water source and to plan for future demands on our limited water supplies.

Summary
Large scale urban stormwater reuse: safe, clear and odourless water supply. This project aims to improve the resilience of Australian water supplies by building capacity in urban stormwater reuse. The project expects to address an industry-identified need to determine the suitability of urban lakes and wetlands for stormwater harvesting and develop chemical-sensory monitoring techniques to assess the quality of harvested water. Expected outcomes include the establishment of satellite-based remot ....Large scale urban stormwater reuse: safe, clear and odourless water supply. This project aims to improve the resilience of Australian water supplies by building capacity in urban stormwater reuse. The project expects to address an industry-identified need to determine the suitability of urban lakes and wetlands for stormwater harvesting and develop chemical-sensory monitoring techniques to assess the quality of harvested water. Expected outcomes include the establishment of satellite-based remote sensing as a key technology for stormwater applications and the widespread use of improved techniques for monitoring odorants by the water industry. This should provide significant benefits by informing adaptive planning and infrastructure readiness at water utilities and guiding Australian policy on stormwater reuse.Read moreRead less
Disinfection by-products formed during drinking water treatment: reducing the unknowns is managing risk. Disinfection of drinking water is a successful measure to reduce water-borne diseases and protect health. However, epidemiological evidence links bladder cancer to disinfection by-products formed during drinking water treatment. Despite decades of research the causative agents remain to be identified. To fill this knowledge gap, this project will quantify the fraction of toxicity that cannot ....Disinfection by-products formed during drinking water treatment: reducing the unknowns is managing risk. Disinfection of drinking water is a successful measure to reduce water-borne diseases and protect health. However, epidemiological evidence links bladder cancer to disinfection by-products formed during drinking water treatment. Despite decades of research the causative agents remain to be identified. To fill this knowledge gap, this project will quantify the fraction of toxicity that cannot be explained by known chemicals in water samples treated with different disinfectants using a combination of chemical analysis and in-vitro bioassays. Samples with high unexplained effects will then be fractionated to isolate toxicologically relevant disinfection by-products, which will ultimately be identified with non-target chemical analysis.Read moreRead less
Carbon nanotube fluidic channels for desalination - interplay of nanoscale confinement and electrostatics. Tiny tubes of carbon, ten thousand times smaller than human hair, allow water to pass through at extraordinary speed. This project aims to understand and improve their salt rejection properties using comprehensive experimental and theoretical approaches. This will provide the impetus and knowledge for developing advanced membranes for desalination
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.
