Fate of engineered nanoparticles: Challenges in informing human and ecological health risk assessments. Engineered nanoparticles (ENPs) have generated significant public and scientific excitement due to their unique properties. This has led to their application in a wide variety of industries (for example, in composite materials and drug delivery). However, there is concern that some ENPs can have detrimental environmental impacts. This project aims to quantify, for the first time, the fate of E ....Fate of engineered nanoparticles: Challenges in informing human and ecological health risk assessments. Engineered nanoparticles (ENPs) have generated significant public and scientific excitement due to their unique properties. This has led to their application in a wide variety of industries (for example, in composite materials and drug delivery). However, there is concern that some ENPs can have detrimental environmental impacts. This project aims to quantify, for the first time, the fate of ENPs that have leached out of commercial products in groundwater systems. This information is expected to assist regulators in developing appropriate legislation to balance the tremendous benefits and potential risks of nanotechnology.Read moreRead less
Assessing risk of oligomictic conditions in sub-tropical water supply lakes. Assessing risk of oligomictic conditions in sub-tropical water supply lakes. This project aims to assess the risk of low rates of mixing in sub-tropical drinking water supply reservoirs, using environmental monitoring and numerical modelling. Emerging evidence suggests sub-tropical drinking water supply reservoirs could transition to low mixing states with increasing age and projected changes in global climate. While th ....Assessing risk of oligomictic conditions in sub-tropical water supply lakes. Assessing risk of oligomictic conditions in sub-tropical water supply lakes. This project aims to assess the risk of low rates of mixing in sub-tropical drinking water supply reservoirs, using environmental monitoring and numerical modelling. Emerging evidence suggests sub-tropical drinking water supply reservoirs could transition to low mixing states with increasing age and projected changes in global climate. While this risk is poorly understood, it could significantly affect the long-term reliability of water supply and potable water treatment costs. Addressing this knowledge gap is expected to develop effective management responses to ensure the long term sustainable use of these water resources.Read moreRead less
Sustainable Water Reuse and Resource Recovery through Cost-Effective BNR. The recycling of treated wastewater effluents is needed to achieve water security, where very low nitrogen (N) and phosphorus (P) levels must be achieved for wastewater to be effectively recycled. This research investigates a more sustainable and cost-effective N&P removal process from wastewater, benefiting the environment and improving the viability of wastewater recycling. Phosphorus is a limited resource worldwide and ....Sustainable Water Reuse and Resource Recovery through Cost-Effective BNR. The recycling of treated wastewater effluents is needed to achieve water security, where very low nitrogen (N) and phosphorus (P) levels must be achieved for wastewater to be effectively recycled. This research investigates a more sustainable and cost-effective N&P removal process from wastewater, benefiting the environment and improving the viability of wastewater recycling. Phosphorus is a limited resource worldwide and will be effectively recovered in the process to be used as a fertiliser. This project develops wastewater treatment process tools, solutions and management strategies that addresses the current challenges of how optimal nutrient removal and recovery from wastewater is achieved, enabling water recycling and saving costs.Read moreRead less
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
Multiscale physics for enhanced oil recovery. The project aims to develop a multiscale mathematical and laboratory modelling methodology for combined enhanced oil recovery (EOR) and CO2 storage, and synthesise the technology for Santos’s Mulberry oilfield as a test case.

The project aims to develop a multiscale mathematical and laboratory modelling methodology for combined enhanced oil recovery (EOR) and CO2 storage, and synthesise the technology for Santos’s Mulberry oilfield as a test case. The multidisciplinary team will develop advanced reservoir- and laboratory-scale mathematical models and novel laboratory methods to enhance the reliability of modern EOR and CO2 storage and increase its uptake by companies in Australia and globally. The expected outcomes are a pioneering methodology with environmental benefits without additional drilling and reduction of greenhouse effect, and economic benefit to the Australian oil industry through increases in productivity.Read moreRead less

Resilience in biogeochemical pathways along a catchment-to-coast continuum. Aquatic systems have degraded more in the past 50 years than any other time in history. Global pressures are further threatening their sustainability, but their complexity makes it difficult to understand how they are responding. This project will combine numerous state-of-the-art approaches to unravel pathways that shape their response.
Resilience of lake ecosystems to water-level manipulation. Which lakes recover from fluctuations in water level and which do not? Manipulations of water levels in lakes will need to intensify as droughts become more frequent. This project will develop robust ways of forecasting how lakes will respond to changes in manipulations of water levels, to minimise extinctions and maintain aesthetics and water quality.
Mass flux pathways in stratified lakes. The aims of this project are to determine parametric descriptions of all transport and mixing mechanisms and their interactions in a stratified lake, validate these parameterisations through process fieldwork (Lake Argyle and Lake St Clair) and then use this understanding to validate and improve a new Lagrangian Dynamic Lake Multi-Basin Model. This project will endeavour to provide lake managers with a new, validated numerical model that will allow inter-s ....Mass flux pathways in stratified lakes. The aims of this project are to determine parametric descriptions of all transport and mixing mechanisms and their interactions in a stratified lake, validate these parameterisations through process fieldwork (Lake Argyle and Lake St Clair) and then use this understanding to validate and improve a new Lagrangian Dynamic Lake Multi-Basin Model. This project will endeavour to provide lake managers with a new, validated numerical model that will allow inter-seasonal simulations with the numerical error being less than the signal. This will be of great importance to ecology, as future advances in that area will largely depend upon a model with correct description of the mass flux paths in a stratified lake.Read moreRead less
