Contamination by poorly treated and untreated sewage can severely degrade the quality of Australian surface waters. However, the behaviour of organic chemicals during conventional sewage treatment processes remains poorly understood. Furthermore, raw sewage pollution is generally not distinguishable from properly discharged treated sewage effluent by current analytical methods. The proposed research will provide a chemical marker for characterising treatment processes and identifying untreated sewage pollution. This will help to identify sources of such pollution so that they may be corrected. A principal outcome of the research will be the improved ability to protect Australia's valuable surface waters from sewage pollution.Read moreRead less

Summary
Efficient PFAS removal from urban wastewater using a novel two-step approach. This project aims to enhance the removal of per- and poly-fluroalkyl substances (PFAS) compounds from municipal wastewater by making two simple amendments to standard wastewater treatment plants. Magnetite nanoparticles will be added to the treatment process, which adsorb PFAS compounds and reduce them to acceptable environmental levels. The resulting sludge will be dried and ashed in a simple and novel self-sustaining ....Efficient PFAS removal from urban wastewater using a novel two-step approach. This project aims to enhance the removal of per- and poly-fluroalkyl substances (PFAS) compounds from municipal wastewater by making two simple amendments to standard wastewater treatment plants. Magnetite nanoparticles will be added to the treatment process, which adsorb PFAS compounds and reduce them to acceptable environmental levels. The resulting sludge will be dried and ashed in a simple and novel self-sustaining smoldering process which will render the captured PFAS to small ash, condensate and gaseous streams suitable for established destruction technologies. The project is expected to provide support to water utilities in achieving sustainable water treatment and result in environmental and social benefits to the community.Read moreRead less
Maximising Bioenergy Recovery from Sewage Sludge. Sewage treatment is producing large amounts of sewage sludge, which represents a substantial, but largely untapped, energy source. This project aims to develop and demonstrate an innovative, economically attractive and environmentally friendly technology, and the underpinning science, to maximize bioenergy recovery from sewage sludge. The technology is based on the treatment of sludge using free ammonia, a by-product of sewage treatment. This pro ....Maximising Bioenergy Recovery from Sewage Sludge. Sewage treatment is producing large amounts of sewage sludge, which represents a substantial, but largely untapped, energy source. This project aims to develop and demonstrate an innovative, economically attractive and environmentally friendly technology, and the underpinning science, to maximize bioenergy recovery from sewage sludge. The technology is based on the treatment of sludge using free ammonia, a by-product of sewage treatment. This project is expected to benefit Australia by substantially reducing the reliance on fossil fuels and accelerating a shift to affordable renewable energy. The outcomes of the project would provide significant energy, economic, environmental and social benefits for Australians. Read moreRead less
Development and modelling of dust suppression technology. Over 50 per cent of Australia's export income is derived from industries that rely on bulk materials handling and processing. With greater throughputs and increasing integration of transport routes, ports and residential communities, more pressure is being placed on industry to control its dust emissions. There is an urgent need for Australia to invest in a more unified and scientific approach to develop and optimise dust suppression tech ....Development and modelling of dust suppression technology. Over 50 per cent of Australia's export income is derived from industries that rely on bulk materials handling and processing. With greater throughputs and increasing integration of transport routes, ports and residential communities, more pressure is being placed on industry to control its dust emissions. There is an urgent need for Australia to invest in a more unified and scientific approach to develop and optimise dust suppression technology for mining and export infrastructure. This project will help secure the sustainability of Australia's bulk exports by ensuring that products can be handled, conveyed and loaded safely and reliably. It will also reduce the risk of exposing workers and the community to unsafe concentrations of airborne dust.Read moreRead less
Disassembly Automation of End-of-Life Electric Vehicle Batteries. This project aims to develop an automated disassembly solution for End-of-Life (EOL) Electric Vehicle (EV) batteries, which is flexible and modular to handle the uncertainties associated with model changes, condition of the EOL battery packs as well as the projected volume growth.

This project aims to develop an automated disassembly solution for End-of-Life (EOL) Electric Vehicle (EV) batteries, which is flexible and modular to handle the uncertainties associated with model changes, condition of the EOL battery packs as well as the projected volume growth. The outcome of this project will lead to a better separation of EV battery components and materials. This will allow recycling of EOL EV batteries with a higher material recovery efficiency and a lower cost due to the significantly reduced labor cost; hence substantially reduce the environmental footprint associated with EOL treatment of these batteries.Read moreRead less

Sporadic influx of oxygen-rich rainwater / groundwater into subsurface waste sites induces dramatic biogeochemical changes which greatly influence the transport of contaminants present. In this project, fundamental knowledge gaps regarding the impacts of redox oscillations upon contaminant behaviour in these sediments will be addressed through a comprehensive program of field studies at a purpose-constructed experimental facility in an existing waste site, and complementary laboratory investigations. The intended outcomes are to improve understanding of contaminant mobility at the field-scale in these pervasive sites spread across the globe, and provide critical insight into their remediation using cost-effective techniques.Read moreRead less
Riparian rehabilitation and ecohydraulics: interactions between flow, sediment, vegetation and bank erosion in longstem tubestock rehabilitation works. Riparian lands are important for maintaining viable ecosystems, improving water quality and reducing sediment yields in rivers and streams. Research in Australia has shown that streambank erosion is the most significant processes in the continuing physical and ecological degradation of riparian zones. The recently developed longstem tubestock sys ....Riparian rehabilitation and ecohydraulics: interactions between flow, sediment, vegetation and bank erosion in longstem tubestock rehabilitation works. Riparian lands are important for maintaining viable ecosystems, improving water quality and reducing sediment yields in rivers and streams. Research in Australia has shown that streambank erosion is the most significant processes in the continuing physical and ecological degradation of riparian zones. The recently developed longstem tubestock system has shown promise in controlling streambank erosion using native vegetation. However, rehabilitation practices rely on ad-hoc recipes without a thorough scientific understanding of near-bank processes. This research will fill this gap by combining field and laboratory experiments on tubestock plantings in order to develop guidelines and predictive tools for riparian zone management.Read moreRead less
Role of vegetation patchiness and self organisation in the ecohydrologic response of water limited ecosystems to climate variability and change. The semi-arid Australian rangelands are some of the most sensitive regions to degradation and climate change, particularly with respect to hydrology and ecology.

The semi-arid Australian rangelands are some of the most sensitive regions to degradation and climate change, particularly with respect to hydrology and ecology. Our predictive ability in these environments is quite poor, however, climatic change (particularly changes in rainfall regimes) are expected to intensify vegetation patterning, intensify erosion and reduce runoff. This project will develop a modelling framework to better understand the impact of these natural (climate variability and change) and anthropogenic (grazing, deforestation) disturbances on runoff and erosion in these regions.Read moreRead less
