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
Process studies for photocatalytic rejuvenation of spent industrial Bayer liquor. A new low-energy photocatalytic process for the continuous treatment of spent liquor from the Bayer process for alumina production has been demonstrated. This new technology can process up to 1500 litres of industrial caustic effluent per day with a reduction in carbon dioxide release. The photo-treated refinery wastewater also provides water savings of 30 per cent.

This project aims to develop a microbial self-healing bio-concrete to extend the service life of wastewater collection and treatment facilities. Water utilities worldwide struggle with asset management, because global warming and extreme weather age and corrode concrete infrastructure. This project will use microbially-induced calcium carbonate precipitation by bacteria to treat wastewater. The bacteria, added to bio-concrete, can fill cracks or reseal corroded areas by using organic substrates from wastewater to generate concrete, thus maintaining structural strength and preventing further damage. This project is expected to enhance the resilience and sustainability of wastewater infrastructure in ever more demanding environments.Read moreRead less

This project aims to bring economic and social benefits to Australian industry and improve the quality of life for people all over the world.Read moreRead less
A new management tool for effective wastewater source control. The use of recycled wastewater can dramatically increase the water supply capacity. However, the potential health risk from possible containments in recycled wastewater must be mitigated. This project aims to develop an effective wastewater source management tool for safeguarding the recycled water production and usage.
Interactions between nanoparticles and bacteria. This project aims to understand how nanoparticles interfere with bacterial metabolism, and how these interactions lead to cell death, lysis and dispersal from biofilms. Intensive use of nanomaterials results in their continuously releases into the environment. While various nanoparticles have inhibitory and even toxic effects on microorganisms in ecosystems, the underlying mechanisms are not understood. This project will investigate model organism ....Interactions between nanoparticles and bacteria. This project aims to understand how nanoparticles interfere with bacterial metabolism, and how these interactions lead to cell death, lysis and dispersal from biofilms. Intensive use of nanomaterials results in their continuously releases into the environment. While various nanoparticles have inhibitory and even toxic effects on microorganisms in ecosystems, the underlying mechanisms are not understood.
