Arsenite oxidation by a novel bacterium that is a candidate for arsenic bioremediation. The arsenic munching microbe NT-26 could help in the fight to clean up arsenic-contaminated mining waste and drinking water. Arsenic poses an environmental problem in countries such as Australia, USA and Canada owing primarily to mining activities. The problem in countries such as Bangladesh and West Bengal are even more serious as these people are dying of arsenic-related diseases as they rely on water conta ....Arsenite oxidation by a novel bacterium that is a candidate for arsenic bioremediation. The arsenic munching microbe NT-26 could help in the fight to clean up arsenic-contaminated mining waste and drinking water. Arsenic poses an environmental problem in countries such as Australia, USA and Canada owing primarily to mining activities. The problem in countries such as Bangladesh and West Bengal are even more serious as these people are dying of arsenic-related diseases as they rely on water containing arsenic as their primary source of drinking water. The outcomes of this research should provide the necessary information for removing arsenic from all types of waters.Read moreRead less

The proposed integrated facility will strongly support collaborative research in areas of high national priority. These are environmental sustainability, development of new materials and designing molecules of therapeutic value on the basis of better understanding the relevant biological processes. This support will lead to maximizing the outcomes of numerous projects already funded by the Australian Research Council which require accurate and highly sensitive analysis. This will improve the cost effectiveness of research funding and will further strengthen the outstanding reputation of Australia science worldwide.Read moreRead less
Development of Leakage Resistant Well-Cements for Geo-Sequestration of Carbon Dioxide Application using Alkali Activated Slag and Geopolymer Cements. The biggest threat facing life now is climate change due to carbon dioxide (CO2) emissions. Extreme weathers are increasing in frequency and intensity, as evidenced by recent bushfires, and it is predicted to get worse unless carbon mitigation strategies are quickly implemented. Geo-sequestration is the technology of capturing and storing of the CO ....Development of Leakage Resistant Well-Cements for Geo-Sequestration of Carbon Dioxide Application using Alkali Activated Slag and Geopolymer Cements. The biggest threat facing life now is climate change due to carbon dioxide (CO2) emissions. Extreme weathers are increasing in frequency and intensity, as evidenced by recent bushfires, and it is predicted to get worse unless carbon mitigation strategies are quickly implemented. Geo-sequestration is the technology of capturing and storing of the CO2 deep below ground for long time (>1000 years). It offers the best hope for large reductions of CO2 emissions. However, CO2-brine stored under pressure is acidic and has the risk of leaking in the long term by dissolving the cement used to seal the pipe wells. This project will develop alternative novel cements which are acid resistant and will not allow CO2 to leak through the sealed wells.Read moreRead less
Application of nano-sized zero valent iron particles to agrochemicals degradation through Fenton's reagent oxidation. Zero-valent iron (ZVI) has been successfully used for the degradation of a wide range of contaminant organics in groundwaters in recent years. The rates of degradation however are relatively slow and render the process unsuitable for situations where there are limits on the time available for reaction. An innovative approach is to couple the dissolution of ZVI with hydrogen perox ....Application of nano-sized zero valent iron particles to agrochemicals degradation through Fenton's reagent oxidation. Zero-valent iron (ZVI) has been successfully used for the degradation of a wide range of contaminant organics in groundwaters in recent years. The rates of degradation however are relatively slow and render the process unsuitable for situations where there are limits on the time available for reaction. An innovative approach is to couple the dissolution of ZVI with hydrogen peroxide addition thereby generating hydroxyl radicals as a result of Fenton's reagent reactions. The efficacy of using this innovative ZVI/H2O2 process to degrade herbicides and pesticides of concern to Australian agriculture is investigated at laboratory and field scale in this project.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.

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

Water resource management is a key issue for environmental sustainability in Australia and strategies that include ecological principles are important to improve present conditions and reduce further degradation. Current biomonitoring methods suffer from a low degree of sensitivity that can seriously impact their effectiveness as early warning signals of ecological disturbance. We propose to combine molecular and ecotoxicological assessment of the effect of zinc toxicity on microbial communities to provide rapid pollution sensitive bioassessment. Our research will lead to a better understanding of the cause and effect of heavy metal pollution within aquatic ecosystems and greater insight on how to reduce and repair the negative effects.Read moreRead less

The advance of ?Green Chemistry? has become a forefront issue in mainstream chemistry. Green Chemistry is aimed at the reduction or elimination of hazardous substances in the design, manufacture and application of chemical products. The advent of ionic liquids (ILs) has made a significant contribution towards these goals. ILs have many beneficial properties including non-volatility, non-flammability, and a large stable liquid range. As ILs advance from academic curiosities to industrial solvents, the need to address the issue of their biodegradability and toxicity is paramount. The key objective of this project is to design new biodegradable and task specific ILs for environmentally friendly industrial use.Read moreRead less
