Optimising nanofiltration and reverse osmosis filtration processes for water recycling: effects of fouling and chemical cleaning on trace contaminant removal. In Australia, water recycling is considered a principal measure to manage the current ongoing water shortage and to better protect the environment. Membrane filtration processes play important roles in the treatment of reclaimed municipal wastewater. However, there is very limited knowledge regarding the reliability of such processes in re ....Optimising nanofiltration and reverse osmosis filtration processes for water recycling: effects of fouling and chemical cleaning on trace contaminant removal. In Australia, water recycling is considered a principal measure to manage the current ongoing water shortage and to better protect the environment. Membrane filtration processes play important roles in the treatment of reclaimed municipal wastewater. However, there is very limited knowledge regarding the reliability of such processes in removing trace contaminants from recycled water, which may result in unintended health consequences. This research will lead to a comprehensive understanding of the removal process of such contaminants by membrane filtration. Consequently, the likely avenue of risk can be eliminated and the treatment process can be optimised to achieve economic savings and environmental protection.Read moreRead less
Integration of Life Cycle Analysis, EnternE, and Economic Models to Sustainable Regional Development. This project involves the development of a novel decision-making framework to support the transition to sustainability within regions. The approach is based on integrating the methodologies of Life Cycle Analysis, externality costing and traditional economic analysis to assess the tradeoffs between economic, environmental and social outcomes.

This project involves the development of a novel decision-making framework to support the transition to sustainability within regions. The approach is based on integrating the methodologies of Life Cycle Analysis, externality costing and traditional economic analysis to assess the tradeoffs between economic, environmental and social outcomes. The integration of these techniques will allow the relative magnitude of positive and negative impacts of development decisions to be reported as an economic unit. This will allow the tradeoffs that occur between economic, environmental and social considerations to be quantified and the sustainability of a development or planning scenario to be assessed.Read moreRead less
Development of in Ground and on Site Technologies for Low Cost Metal Remediation of Remote Contaminated Sites.

The clean-up of abandoned Antarctic sites is seen as a priority, and research into low-impact technology is central to meeting established remediation goals. Successful development of a low-cost in-situ remediation scheme will not only serve to protect vulnerable Antarctic habitats in Australian stewardship, but will do much to cement Australia as a global leader in environmental protection offering as it does, a generic cold region hydrocarbon remediation solution.Read moreRead less
The development of low cost sorbents for removal of contaminants in ground water at cold regions contaminated sites. Contamination of soils and waters as a result of industrial and other human activities, is a significant global environmental issue.

Contamination of soils and waters as a result of industrial and other human activities, is a significant global environmental issue. Both Australia and Japan have a large legacy of hydrocarbon and heavy metals contamination from mining activities and industry. This project aims to address hydrocarbon and heavy metals contamination through investigation of novel, low-cost sorbents suitable for implementation in passive in-situ remediation technologies. This will be achieved through the combined efforts of Australian and Japanese scientists who are expert in the fields of water treatment and chemical synthesis of sorbent materials.Read moreRead less

This project aims to develop management approaches to enable the use of anaerobic co-digestion — the conversion of organic wastes and wastewater sludge to biogas for electricity production. Anaerobic co-digestion has the potential to bring significant economic savings to water stakeholders and environmental benefits to communities. However, full-scale deployment faces fundamental challenges in terms of managing impacts on downstream processes (e.g. odour, dewaterability, biogas quality, and nutrient build-up). The analytical framework and analytics tool to be developed in this project by an interdisciplinary team with expertise in process engineering, biochemistry, analytical chemistry and analytics, is expected to enable water stakeholders to cost-effectively manage these impacts and thus realise the benefits of co-digestion.Read moreRead less
Iron and phosphorus recovery from ferric precipitation sludge. To minimise health risks and environmental pollution, water and wastewater treatment processes often use iron salts to eliminate phosphate and other pollutants. This generates large amounts of chemical sludge that is typically sent to landfill. The benefits of this new process will be the recovery of both the iron, which can be reused in the process, and the phosphate, which is a key component in fertiliser. Since phosphate is a limi ....Iron and phosphorus recovery from ferric precipitation sludge. To minimise health risks and environmental pollution, water and wastewater treatment processes often use iron salts to eliminate phosphate and other pollutants. This generates large amounts of chemical sludge that is typically sent to landfill. The benefits of this new process will be the recovery of both the iron, which can be reused in the process, and the phosphate, which is a key component in fertiliser. Since phosphate is a limited natural resource with an increasingly high value, the recovery and recycling of this critical element in food production is highly important. The process will also avoid a large part of the sludge production and will make the water treatment processes more cost-effective.Read moreRead less
Impact of Fouling on Retention of Contaminants in Electrodialysis for Brackish Water and Wastewater Applications. Water desalination and water recycling are both of utmost importance in the current global water crisis. Reverse osmosis is a commonly used process in both areas but this process has two main limitations (1) it is limited in water recovery by the concentration of salts, and (2) it produces a relatively large amount of concentrates that require disposal. Using electrodialysis to treat ....Impact of Fouling on Retention of Contaminants in Electrodialysis for Brackish Water and Wastewater Applications. Water desalination and water recycling are both of utmost importance in the current global water crisis. Reverse osmosis is a commonly used process in both areas but this process has two main limitations (1) it is limited in water recovery by the concentration of salts, and (2) it produces a relatively large amount of concentrates that require disposal. Using electrodialysis to treat such concentrates will decrease the salinity problem caused by disposal and also increase the water efficiency of the treatment process. In this research project the potential performance limitations fouling and micropollutant removal will be investigated and hence the performance improved.Read moreRead less

Large amounts of waste plastics go to landfill daily. Landfill simply buries our wastes for future generations and can contribute to the contamination of ground water. This project aims to develop an advanced pyrolysis technology to produce transport diesel from waste plastics. This technology is an economically attractive and environmentally friendly way for the disposal of waste plastics without any environmental problems associated with the landfill or direct incineration of waste plastics. As this technology is based on advances in Australian research and development, exporting this to other countries will further enhance its economic and social benefits to Australia.Read moreRead less
