Water is a critical resource for societies worldwide and Australia is one of the driest nations on Earth. Options to treat ‘used’ or lower quality waters for reuse are becoming a necessity. This project aims to implement advanced nanotechnology solutions to improve performance characteristics of widely adopted water treatment membranes, which have the potential to reduce water treatment costs in Australia. This is made possible by the collaboration with Australia's largest manufacturer of water treatment membranes. The outcomes will lead towards a lower maintenance water treatment technology available to communities, at lower cost. The application of such a technology will span from local small scale to major installations worldwide.Read moreRead less
Influence of Impurities in Commercial Solvent Extraction Processes. This project directly supports the solvent extraction industry in Australia. This industry is responsible for generating in excess of $600M annually of export earnings for Australia. This type of technology can be applied in the recovery of base metals such as coper, nickel, cobalt, etc and in the environmental area for the clean up of heavy metals from waste water. Solvent extraction has the advantage of high selectivity that ....Influence of Impurities in Commercial Solvent Extraction Processes.

This type of technology can be applied in the recovery of base metals such as coper, nickel, cobalt, etc and in the environmental area for the clean up of heavy metals from waste water. Solvent extraction has the advantage of high selectivity that enables metals to be recovered and recycled, thus reducing the wastage of these metals in, for example, the chromium plating process.Read moreRead less
Combined Ozonation-Flotation for the Treatment of Potable Water. Water Authorities are tightly regulated to guarantee removal of pollutants such as algal cells and toxins, cryptosporidium oocysts, and geosmin from drinking water. Processing options such as membrane filtration are effective but become very expensive when continuously operated to protect against occasional contamination events. This project aims to develop a fully-integrated process combining flotation and ozonation which can be ....Combined Ozonation-Flotation for the Treatment of Potable Water. Water Authorities are tightly regulated to guarantee removal of pollutants such as algal cells and toxins, cryptosporidium oocysts, and geosmin from drinking water. Processing options such as membrane filtration are effective but become very expensive when continuously operated to protect against occasional contamination events. This project aims to develop a fully-integrated process combining flotation and ozonation which can be operated continuously when required in a number of different modes to provide a barrier against a range of contamination events. The process utilises much of the existing water treatment infrastructure reducing capital and operating costs.Read moreRead less
Lowering membrane fouling by matching pre-treatment to membrane type. Delivery of potable and recycled water to communities and industry increasingly uses membrane treatment to ensure high standards of water quality, particularly as water scarcity leads to the use of poor quality water sources. Fouling of membranes occurs as water is treated, adding expense and complexity to the process. Reducing fouling will lower the cost of water treatment and improve the economics of treating water in smal ....Lowering membrane fouling by matching pre-treatment to membrane type. Delivery of potable and recycled water to communities and industry increasingly uses membrane treatment to ensure high standards of water quality, particularly as water scarcity leads to the use of poor quality water sources. Fouling of membranes occurs as water is treated, adding expense and complexity to the process. Reducing fouling will lower the cost of water treatment and improve the economics of treating water in smaller systems at source. This will enable greater reliability of localised treatment, which will reduce pumping requirements and decrease both cost and carbon emissions. Read moreRead less
The Role of the Interface in Solvent Extraction. This project involves a fundamental study of the kinetics of reactions that occur in solvent extraction processes used for separation of many of Australia's metals from minerals. The understanding gained from this will enable a greater efficiency to be obtained from Australia's minerals industry. In particular, it is intended to investigate the role of additives on the kinetics of metal extraction; these additives either enter the solution from ....The Role of the Interface in Solvent Extraction. This project involves a fundamental study of the kinetics of reactions that occur in solvent extraction processes used for separation of many of Australia's metals from minerals. The understanding gained from this will enable a greater efficiency to be obtained from Australia's minerals industry. In particular, it is intended to investigate the role of additives on the kinetics of metal extraction; these additives either enter the solution from the ore or are added as flocculants during the process, and have a significant effect on the performance. With the move to smaller, shorter residence time contactors, this has become increasingly important if these new contactors are to be used efficiently.Read moreRead less

Desalting reclaimed wastewater to safeguard Virginia's horticultural industries. Virginia is a major horticultural region of South Australia undergoing rapid expansion. Groundwater resources are depleted and reclaimed sewage effluent from Adelaide is required for irrigation. Unfortunately, the effluent is frequently too saline. Large-scale desalting is being considered. A pilot-scale plant will be built to evaluate suitable desalting processes (e.g. reverse osmosis) for reducing the effluent ....Desalting reclaimed wastewater to safeguard Virginia's horticultural industries. Virginia is a major horticultural region of South Australia undergoing rapid expansion. Groundwater resources are depleted and reclaimed sewage effluent from Adelaide is required for irrigation. Unfortunately, the effluent is frequently too saline. Large-scale desalting is being considered. A pilot-scale plant will be built to evaluate suitable desalting processes (e.g. reverse osmosis) for reducing the effluent's salt content. Original research will: (i) synthesize the best combination of technologies to produce effluent streams of varying salinity for matching different crop requirements; and (ii) optimise delivery and storage of effluent streams using new storage(s) and the region's multiple aquifer and surface storages.Read moreRead less

Characterisation and Treatment of Reverse Osmosis Concentrates from Water Recycling Applications. Concentrates from reverse osmosis (RO) pose a considerable threat to both the environment but also the successful implementation of reverse osmosis as a technology. Naturally, the concentrate contains everything that the RO retains and hence contaminants such as viruses, organics such as pharmaceutically active compounds and hormones as well as nutrients and salinity.

Concentrates from reverse osmosis (RO) pose a considerable threat to both the environment but also the successful implementation of reverse osmosis as a technology. Naturally, the concentrate contains everything that the RO retains and hence contaminants such as viruses, organics such as pharmaceutically active compounds and hormones as well as nutrients and salinity. Treatment of such waste streams will enhance the health of receiving water bodies and reduce the risk of increased build up of contaminants if wastes are recycled into wastewater treatment plants. New ways to treat such contaminants will be explored, the efficiency and cost evaluated in the broader water cycle and sustainability framework.Read moreRead less
