Desalination is being established in response to climate change and growing demands on existing supplies. Fresh water from infinitely abundant ocean sources using little energy input will benefit communities by providing affordably a vital resource with minimal greenhouse gas emissions. Fresh water from current desalination costs $2 per kl, being a major expense for a vital resource normally $0.2 per kl. As energy input accounts for half of the desalination cost, the smart ion-selective membrane to be developed in this project has the capability to reduce desalinated water price by 50%. Such an advancement derived from fundamental material properties is a novel contribution to both science and membrane desalinationRead moreRead less

The management of greenhouse and other acid gas emissions is vital to a sustainable future of both the economy and the ecosystem. This project will develop novel nano-materials for gas separation by tethering organic functional groups to the surface of porous inorganic supports. These materials offer the promise of combining the high selectivity and high capacity of liquid phase absorption systems with the rapid transport rates of gas-solid adsorption systems. Success would open up several new possibilities for reengineering gas separation systems based on the use of these materials in solution, as solid phase adsorbents (pressure swing adsorption) and/or as permeselective gas membranes.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 enables metals to be recovered and recycled, thus reducing the wastage of these metals in, for example, the chromium plating process.Read moreRead less
The Effective Treatment of Hot Dip Galvanizing Effluent Streams. Hot Dip galvanizing effluent represents a significant environmental hazard. This wastewater is currently trucked offsite and treated by contractors to precipitate a heavy metal sludge that is disposed of through landfill.

Hot Dip galvanizing effluent represents a significant environmental hazard. This wastewater is currently trucked offsite and treated by contractors to precipitate a heavy metal sludge that is disposed of through landfill. Industrial Galvanisers, as the largest hot dip galvanizing company within Australia, are keen to eliminate this hazard. We will consider the use of an innovative membrane based process for this purpose; to recover valuable zinc and iron compounds from the effluent and allow the water to be re-utilised. If successful, this project will lead to a pilot plant wastewater treatment plant being constructed at an Industrial Galvanizers site.Read moreRead less
Practical Application of Filtration Theory to the Minerals Industry. The project aims to provide a quantitative basis for the selection, design, operation and maintenance of filter devices in the minerals industry. This will be achieved through characterisation of materials to be filtered by developing a model of the true role of the membrane in filtration. Experimental parameters will be input to first principles filtration models. This will reduce the incidence of poor operational outcomes ....Practical Application of Filtration Theory to the Minerals Industry.

Ultrafiltration of whole milk solutions will be extended to maximise the product protein concentration. Electrodialysis and nanofiltration will be tailored to separate salts from lactose and produce 'designer' products with minimum wastage and energy consumption. Production of lactitol from dairy lactose, a potential new manufacturing operation for Australia, will be assessed. This project will result in diversion of quality ingredients from commodity markets to products with significant added value. The Korumburra region will benefit financially and socially from expansion in the local dairy industry.

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
