Control of Hydrophobic Interactions between Gas Bubbles in Water and Their Role in Gas Hydrate Formation and Dissociation. Methane is a powerful greenhouse gas, and its release in deep oceans and permafrost regions due to decomposition of methane hydrate, an ice-like crystalline, could potentially pose devastating threat to mankind. On the other hand, methane hydrate represents a vast energy potential to Australia and the remainder of the world. Understanding the mechanism of gas hydrate formati ....Control of Hydrophobic Interactions between Gas Bubbles in Water and Their Role in Gas Hydrate Formation and Dissociation. Methane is a powerful greenhouse gas, and its release in deep oceans and permafrost regions due to decomposition of methane hydrate, an ice-like crystalline, could potentially pose devastating threat to mankind. On the other hand, methane hydrate represents a vast energy potential to Australia and the remainder of the world. Understanding the mechanism of gas hydrate formation and dissociation is of fundamental importance to methane extraction and capture. This project employs state-of-the-art surface analytical tools to explore the mechanism of gas hydrate formation. The outcomes will strengthen Australia's leading role in scientific and technological development in this field. Read moreRead less
Fluidised bed biosorption-flocculation granular activated carbon (FBBSF-GAC) for membrane filtration in wastewater reuse. Water resource is limited and has been continuously decreasing. The idea of recycling and reusing of wastewater has been adopted for irrigation, industry and other non-potable uses. In Australia, wastewater reuse is now considered a key strategy for conserving water at national, state and local level. In this study, the proposed treatment unit is to produce a superior effluen ....Fluidised bed biosorption-flocculation granular activated carbon (FBBSF-GAC) for membrane filtration in wastewater reuse. Water resource is limited and has been continuously decreasing. The idea of recycling and reusing of wastewater has been adopted for irrigation, industry and other non-potable uses. In Australia, wastewater reuse is now considered a key strategy for conserving water at national, state and local level. In this study, the proposed treatment unit is to produce a superior effluent quality for water reuse while minimize membrane fouling of the membrane filtration system. Hence, it will benefit water industries globally and communities in Australia. There will be a major export opportunity from Australia to supply efficient, low-cost and sustainable flocculant together with an improved treatment system worldwide.Read moreRead less
Novel Nanomaterials for Photocatalytic Water Purification - Science and Application. Water is rapidly becoming Australia's most critical natural resource, and there is an urgent need to re-use and recycle water from domestic use (graywater) and industry, as well as utilisation of larger scale harvesting of rainwater. The outcome of this project will be a technology which can remove organic material (biological and non-biological) from water, enabling a greater range of uses of wastewater.

The outcome of this project will be a technology which can remove organic material (biological and non-biological) from water, enabling a greater range of uses of wastewater. This technology will play a significant role in delivering future water security, and developing new industries involved in manufacture and export of water treatment technologies. This project directly addresses the National Priority Research area of water, and international priorities involving greater re-use and recycling of water.Read moreRead less
Research and development of devices to improve the quality of stormwater by removal of gross pollutants such as soil, litter and sediment. Oil,litter and sediment are serious pollutants in stormwater which go hand in hand with human and industrial activity. An outcome of this research will be to develop a device capable of removing such gross pollutants from stormwater at higher efficiencies than that currently commercially available. Vital wetland resources such as Moreton Bay near Brisbane, a ....Research and development of devices to improve the quality of stormwater by removal of gross pollutants such as soil, litter and sediment. Oil,litter and sediment are serious pollutants in stormwater which go hand in hand with human and industrial activity. An outcome of this research will be to develop a device capable of removing such gross pollutants from stormwater at higher efficiencies than that currently commercially available. Vital wetland resources such as Moreton Bay near Brisbane, a wetland of international significance that contributes around $400 million to the local economy,are under threat from polluted stormwater. Similar problems are occuring right around the entire coast of Australia and also in some inland waterways.Read moreRead less
What are the risks of viral infections in drinking water storages? South East Queensland's population growth is the fastest in Australia but our drinking water supplies will be fully allocated by 2020. Maintaining public health standards of the existing supplies is vital. Declines in water quality in these unprotected catchments will influence viral infection but we don't know how. Toxin producing algae (cyanobacteria) also bloom and we don't know why. We have an innovative approach to determine ....What are the risks of viral infections in drinking water storages? South East Queensland's population growth is the fastest in Australia but our drinking water supplies will be fully allocated by 2020. Maintaining public health standards of the existing supplies is vital. Declines in water quality in these unprotected catchments will influence viral infection but we don't know how. Toxin producing algae (cyanobacteria) also bloom and we don't know why. We have an innovative approach to determine how changing water quality influences viral infection of toxic cyanobacteria and the potential of human viral pathogens (disease causing) to infect. This new knowledge will improve SEQWater's ability to manage public and ecosystem health risks in drinking water storages.Read moreRead less
