Summary
Nanostructures derived from metal-organic frameworks for sodium-ion batteries. This project aims to overcome poor reaction kinetics and the lack of effective anode materials owing to the large size of sodium-ions in high performance sodium-ion batteries.

This project aims to overcome poor reaction kinetics and the lack of effective anode materials owing to the large size of sodium-ions in high performance sodium-ion batteries. The project will explore a series of functional nanomaterials with unique nanostructures and complex compositions, enabled by metal-organic framework assisted synthetic methods. High performance sodium ion batteries are demonstrating great potential to meet the future demand for large-scale and low-cost stationary energy storage. However, their practical implementation is still hindered by their poor reaction kinetics and the lack of effective anode materials owing to the large size of sodium-ions. The project outcomes will promote the commercialisation of sodium ion batteries and power Australia’s sustainable economy in the long run.Read moreRead less
In situ desalination with membranes for climate resilient irrigation. This project aims to design a climate-resilient irrigation system that minimises evaporative losses and can operate on brackish groundwater without reducing crop yield or damaging soil structure. To do so, it will improve a sub-surface irrigation system that uses desalination membranes. The irrigation system is built on understanding water transport under tension caused by plant transpiration and identifying membranes that can ....In situ desalination with membranes for climate resilient irrigation.

To do so, it will improve a sub-surface irrigation system that uses desalination membranes. The irrigation system is built on understanding water transport under tension caused by plant transpiration and identifying membranes that can supply water and remove salt without cativation.Read moreRead less
Adsorption and Removal of Trace Organic Compounds by Membrane Processes used in Water Treatment and Wastewater Recycling. Recycling of municipal wastewaters is of growing importance as a resource-conservation and environmental-protection measure in Australia. A major impediment to increased rates of water recycling is a lack of knowledge regarding the presence, fate and removal of key trace organic compounds. Among these key contaminants are pharmaceutically active compounds (PhACs) and steroid ....Adsorption and Removal of Trace Organic Compounds by Membrane Processes used in Water Treatment and Wastewater Recycling. Recycling of municipal wastewaters is of growing importance as a resource-conservation and environmental-protection measure in Australia. A major impediment to increased rates of water recycling is a lack of knowledge regarding the presence, fate and removal of key trace organic compounds. Among these key contaminants are pharmaceutically active compounds (PhACs) and steroid hormones. This research will lead to a thorough understanding of the mechanisms involved with the removal of these compounds by membrane treatment applications. Major benefits will be enhanced ability to undertake risk management and a lowering of costs associated with full-scale water treatment applications.Read moreRead less
Defining Fundamental Principles for the Design and Operation of Membrane Systems from Time-Varying Performance Analysis. To date, much of the process improvement for industrial application of membrane technology has revolved around polymer science based development of membrane materials and process and module changes resulting from the application of basic (often simplistic) engineering principles. While some future improvements may still come from these areas, the most dramatic advances are li ....Defining Fundamental Principles for the Design and Operation of Membrane Systems from Time-Varying Performance Analysis. To date, much of the process improvement for industrial application of membrane technology has revolved around polymer science based development of membrane materials and process and module changes resulting from the application of basic (often simplistic) engineering principles. While some future improvements may still come from these areas, the most dramatic advances are likely to be derived from the application of advanced engineering principles to this complex system. This project will integrate advanced CFD modelling and control principles for the design and operation of membrane systems in order to develop fundamental understanding that should lead to significant process improvements.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
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. Treatment of such waste streams ....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. 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
Feedback destabilising control of electro-osmotic flow for reducing fouling and enhancing productivity of membrane systems.

Development of Vibratory Submerged Membrane Systems for Water and Wastewater Treatment. While there has been a dramatic increase in the use of submerged membrane systems in recent years, fouling of these membranes remains a major limitation to their more widespread use with the commonly used antifouling approach of bubbling with air exhibiting serious limitations.

While there has been a dramatic increase in the use of submerged membrane systems in recent years, fouling of these membranes remains a major limitation to their more widespread use with the commonly used antifouling approach of bubbling with air exhibiting serious limitations. Low frequency vibration of submerged membranes appears to offer substantial benefits with regard to increased flexibility of operation (such as the ability for rapid turn up/turn down and the ability to minimise fouling in anaerobic systems)and is likely to further extend the use of membranes in water and wastewater treatment.Read moreRead less
