This project aims to investigate the extraction of renewable energy from new pavements constructed with low-carbon recycled demolition wastes. The proposed research will generate new knowledge on the thermo-geomechanical responses of pavements when harvesting heat energy under dynamic loads, using experimental and numerical approaches, including field trials. The outcomes and benefits will include strategic long-term collaboration with industry to develop ‘Geothermal Pavements’, with potential for commercial applications. The translation of this research will contribute to meeting future energy needs, while significantly reducing carbon emissions and diverting demolition wastes from landfills.Read moreRead less
Novel Molecular Markers for the Historical Source Tracing of Faecal Contamination in Urban Water Catchments. Protection of the microbiological quality of raw water systems is imperative to maintaining the safety of drinking water. Monitoring of water samples for the presence of microbes that indicate the presence of faecal pollution can be used to assess the possible threats to human health. The objective of this research is to apply molecular genetic methods to determine their effectiveness as ....Novel Molecular Markers for the Historical Source Tracing of Faecal Contamination in Urban Water Catchments. Protection of the microbiological quality of raw water systems is imperative to maintaining the safety of drinking water. Monitoring of water samples for the presence of microbes that indicate the presence of faecal pollution can be used to assess the possible threats to human health. The objective of this research is to apply molecular genetic methods to determine their effectiveness as tools for the tracking and tracing of faecal bacteria within drinking water catchments. We have chosen the spore-former Clostridium perfringens as an indicator of both long and short-term sewage contamination. It will enable us to predict the origin of contamination and thus identify potential sources of faecal pollution that require remediation.Read moreRead less
Long-term acid rock and tailings drainage mitigation through source control. Effective long-term management of acid rock drainage (ARD) from sulfidic mine wastes in current, exhausted and legacy mine sites is of critical importance to communities and for sustainable mining. An optimised geochemical and microbial multi-barrier approach to long-term reduction of ARD to environmentally acceptable rates will be developed by this project.
Biological phosphorous removal for wastewater treatment. The aim is to provide a scientific basis for understanding how phosphorous can be removed in wastewater treatment plants, using environmentally safe biological methods rather than by using chemicals. This is expected to lead to improved performance in wastewater treatment plants, which will be of economic and environmental benefit, particularly to regional communities in inland Australia.
Development and modelling of dust suppression technology. Over 50 per cent of Australia's export income is derived from industries that rely on bulk materials handling and processing. With greater throughputs and increasing integration of transport routes, ports and residential communities, more pressure is being placed on industry to control its dust emissions. There is an urgent need for Australia to invest in a more unified and scientific approach to develop and optimise dust suppression tech ....Development and modelling of dust suppression technology. Over 50 per cent of Australia's export income is derived from industries that rely on bulk materials handling and processing. With greater throughputs and increasing integration of transport routes, ports and residential communities, more pressure is being placed on industry to control its dust emissions. There is an urgent need for Australia to invest in a more unified and scientific approach to develop and optimise dust suppression technology for mining and export infrastructure. This project will help secure the sustainability of Australia's bulk exports by ensuring that products can be handled, conveyed and loaded safely and reliably. It will also reduce the risk of exposing workers and the community to unsafe concentrations of airborne dust.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
Application of the MIEXR DOC process to membrane hybrid systems for water reuse. Fresh water is increasingly scarce in Australia and wastewater reuse is being advocated as a strategy for both meeting our needs and protecting the environment. This research will test the magnetic ion exchange (MIEX) process as a pretreatment for a membrane-flocculation hybrid system (MFHS). MIEX will remove small and medium molecular weight organics and minimize membrane fouling. Large molecular weight organics, s ....Application of the MIEXR DOC process to membrane hybrid systems for water reuse. Fresh water is increasingly scarce in Australia and wastewater reuse is being advocated as a strategy for both meeting our needs and protecting the environment. This research will test the magnetic ion exchange (MIEX) process as a pretreatment for a membrane-flocculation hybrid system (MFHS). MIEX will remove small and medium molecular weight organics and minimize membrane fouling. Large molecular weight organics, suspended solids and micro-organisms will be removed by MFHS. This research will pioneer a novel hybrid system for treatment and reuse of domestic wastewater for non-drinking purposes and provide high quality research training of a doctoral student.Read moreRead less
Enhanced recovery and concentration of cenospheres from fly ash. The purpose of this project is to investigate the recovery of valuable particles, referred to as cenospheres, from the fly ash waste of coal fired power stations. An understanding of the complex gravitational settling behaviour of fly ash suspensions in inclined channels will lead to a new technology for recovering and concentrating the particles.

This project aims to develop a photonic sensor capability to measure chemical compounds that cause concrete corrosion in waste-water pipes. Sustainable management of urban waste-water networks is a global problem. Hydrogen sulphide and water in air pockets cause concrete attack that results in premature pipe failure with high financial, public health and environmental costs. Unlike current qualitative methods, which rely on often dangerous visual inspection of pipes to identify concrete corrosion, this project will develop a quantitative sensing system that directly measures key chemicals, targeting the cause and not the effect. This research is expected to extend the life of waste-water networks and reduce cost to the public.Read moreRead less
