Algal control using multi-functional, cold plasma activated microbubbles . Climate change is driving a proliferation of nuisance and harmful algal blooms in our water supply systems, which urgently require cost efficient and effective control strategies. Paradoxically, algal biotechnology is a growth industry with application in food, agriculture and energy; realising this potential requires state-of-the-art technology to optimise production, harvesting and extraction.

Climate change is driving a proliferation of nuisance and harmful algal blooms in our water supply systems, which urgently require cost efficient and effective control strategies. Paradoxically, algal biotechnology is a growth industry with application in food, agriculture and energy; realising this potential requires state-of-the-art technology to optimise production, harvesting and extraction. The aim of this proposal is to develop cutting edge technology that uses cold plasma activated microbubbles to control algal populations. We propose that by tuning the plasma composition, this technology could both selectively disrupt and destroy algal matter and enhance algal cell growth, benefiting both water and biotechnology industries.

This project aims to establish a novel pathway for transforming complex waste otherwise destined for landfill into valuable products and resources. By leveraging high temperature reactions, the team plans to thermally isolate useful carbons and silica from within automotive shredder residue (ASR) in situ, to produce activated carbon products and silica layers, and so completely recycle this bulk toxic waste for the first time. Such innovative new pathways for separating out valuable materials from complex and toxic wastes offer industries an alternative low-cost and sustainable source of raw materials, while reducing pressures on landfills and finite natural resources.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. Our predictive ability in these environments is quite poor, however, climatic change (particularly changes in rainfall regimes) are expected to intensify vegetation patterning, intensify erosi ....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. 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

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

The increasing application of antimicrobial compounds in pharmaceutical and personal care products (PPCPs) requires improved understanding of their impact on the environment. Wastewater treatment plants (WWTPs) are a major removal process, however little is known about why certain PPCPs are removed during wastewater treatment and other are not. The project aims to study the fate of PPCPs and the spread of bacterial resistance in wastewater treatment. Studies will compare the effects of different treatment processes, operational conditions and environmental factors on the removal and treatment of PPCPs. The outcome will be the development of more sustainable WWTPs design and operation in terms of PPCPs removal.Read moreRead less
Hydrologic effects of human and climatic stresses in water-limited areas: role of coevolving runoff, vegetation and landforms for adaptive management. Semiarid rangelands cover over 70 per cent of the Australian continent. These areas already face serious degradation problems.

Semiarid rangelands cover over 70 per cent of the Australian continent. These areas already face serious degradation problems. Observed trends in rainfall variability indicate that high rainfall pulses and dry periods will intensify, with serious implications for hydrology and erosion. The impact of these trends in addition to increasing human pressures could have devastating socioeconomic consequences for these areas. This project, by examining in detail the hydrologic and soil transport processes in semiarid rangelands, will lead to: better understanding of the dryland response to anthropogenic and climatic stresses; and, improvement of strategies and methods for the management and restoration of these areas.Read moreRead less

Engineered osmosis (EO) is based on the principles of natural osmosis and is an emerging technology for low energy desalination and power generation by pressure-retarded osmosis. However, the process is limited by the challenge of the internal concentration polarisation (ICP) effects experienced when currently available membranes are used. Therefore, the aims of this project are to enhance our understanding of the ICP phenomenon in EO process and to evaluate strategies to mitigate the influence of ICP effects on the performance of the EO process by incorporating innovative functionalised nanofibrous support layers for thin-film composite EO membrane. A significant increase of water flux and mechanical strength is anticipated.Read moreRead less
