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

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

Interactions between plants and faecal pathogens in urban water treatment: significance of soil microbes, plant debris, root exudates and rhizosphere. It is important to treat pathogens in stormwater and wastewater before release into downstream recreational waters or harvesting. Using plants in water treatment improves the removal of pollutants of concern to human and ecosystem health.

It is important to treat pathogens in stormwater and wastewater before release into downstream recreational waters or harvesting. Using plants in water treatment improves the removal of pollutants of concern to human and ecosystem health. However, the exact mechanisms which generate this improvement remain unknown, and this is especially true for faecal pathogen removal. This project will enhance our understanding of the interactive role that roots, their exudates, plant debris and soil microbes play in faecal pathogen removal in urban water treatment systems. Through this understanding, this project will lead to optimised low-energy, low-tech and low-maintenance treatment systems.Read moreRead less

Virtual reality for planning of green urban water infrastructure. This project aims to research the planning-technical-social dynamics of Water Sensitive Urban Design (WSUD) infrastructure. WSUD management has become financially and logistically unsustainable due to major urban growth and a rapid uptake in WSUD assets. Solving this problem is, however, complex, as stakeholders have conflicting needs and tacit knowledge that is difficult to quantify.

This project aims to research the planning-technical-social dynamics of Water Sensitive Urban Design (WSUD) infrastructure. WSUD management has become financially and logistically unsustainable due to major urban growth and a rapid uptake in WSUD assets. Solving this problem is, however, complex, as stakeholders have conflicting needs and tacit knowledge that is difficult to quantify. Using emerging virtual reality technology, participatory planning and operational models, this project intends to improve WSUD modelling science through integrated modelling. The anticipated outcome is more holistic and economically efficient planning of WSUD layouts in future cities. This is expected to address growing concerns about adequately managing these systems and ensure that they deliver intended environmental protection, liveability and public health benefits.Read moreRead less

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.

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
