Microplastics in Landfills and Surrounding Environments. This project aims to build a risk-based framework for managing micro- and nano-plastic particles in landfills and surrounding environments. It expects to develop a new experimentally validated theory of micro/nano-plastic transport in soils, focussing on lining systems used in landfills worldwide to protect aquifers from contamination. The project will use state-of-the-art experimental, theoretical and computational approaches to generate ....Microplastics in Landfills and Surrounding Environments. This project aims to build a risk-based framework for managing micro- and nano-plastic particles in landfills and surrounding environments. It expects to develop a new experimentally validated theory of micro/nano-plastic transport in soils, focussing on lining systems used in landfills worldwide to protect aquifers from contamination. The project will use state-of-the-art experimental, theoretical and computational approaches to generate new knowledge on micro/nano-plastic fate in lining systems and their effects on the mobility of heavy metals and organic pollutants. This should provide significant benefits including safe plastic containment and groundwater protection from landfill waste, a major reservoir of plastic in the environment.Read moreRead less
Activating lazy stormwater wetlands through real time monitoring & control. Constructed stormwater wetlands are the last line of defence preventing pollution of urban waterways, but wetlands often fail, with their passive operation unable to adapt to the highly variable climate and hydrology they experience. This project aims to use advances in real-time control technology to turn these lazy wetlands into active wetland systems, optimising their performance. It aims to deliver new-generation tec ....Activating lazy stormwater wetlands through real time monitoring & control. Constructed stormwater wetlands are the last line of defence preventing pollution of urban waterways, but wetlands often fail, with their passive operation unable to adapt to the highly variable climate and hydrology they experience. This project aims to use advances in real-time control technology to turn these lazy wetlands into active wetland systems, optimising their performance. It aims to deliver new-generation technologies to enhance water quality treatment, enhance urban water security and guarantee environmental flows to maintain healthy waterways. Working in partnership with waterway managers and water retailers, this project strives to deliver a nationally and globally relevant technology to change how we manage water in cities.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
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.
Performance of waste stabilisation ponds: controlling factors, novel performance indicators, and risk assessment. As the world population increases, maintaining robust, cost-effective and environmentally safe wastewater treatment systems is of vital importance. This project will enhance the ability to design, operate and manage Australia's extensive wastewater infrastructure for safer and more sustainable water resources in Australia and the world.

Summary
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. However, the exact mechanisms which generate this improvement remain unknown, and this is especially true for ....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. 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
