To date, much of the process improvement for industrial application of membrane technology has revolved around polymer science based development of membrane materials and process and module changes resulting from the application of basic (often simplistic) engineering principles. While some future improvements may still come from these areas, the most dramatic advances are likely to be derived from the application of advanced engineering principles to this complex system. This project will integrate advanced CFD modelling and control principles for the design and operation of membrane systems in order to develop fundamental understanding that should lead to significant process improvements.Read moreRead less

Large amounts of waste plastics go to landfill daily. Landfill simply buries our wastes for future generations and can contribute to the contamination of ground water. This project aims to develop an advanced pyrolysis technology to produce transport diesel from waste plastics. This technology is an economically attractive and environmentally friendly way for the disposal of waste plastics without any environmental problems associated with the landfill or direct incineration of waste plastics. As this technology is based on advances in Australian research and development, exporting this to other countries will further enhance its economic and social benefits to Australia.Read moreRead less

This project aims to understand the interaction of light responsive nano-metals and metal oxide supports in photo-thermal catalysis, and channel light and heat to efficiently drive catalytic reactions. From this understanding, it will develop principles to activate the active site of metal oxides and control catalytic activity with high selectivity and stability. It will use this knowledge to selectively oxidate methane and oxidative coupling of methane reactions. The expected outcome is an inexpensive green catalysis method for chemical manufacture. This should lower the amount of waste, decrease energy consumption and improve human health, finite global resources and quality of life.Read moreRead less

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
Determination of the fate of dissolved organic nitrogen in biological nutrient removal (BNR) processes and development of appropriate treatment technologies. The aim of this project is to better characterise the dissolved organic nitrogen (DON) in sewage treatment plant influent, determine its fate in biological nutrient removal (BNR) plants, and to evaluate and develop an appropriate treatment technology.

The aim of this project is to better characterise the dissolved organic nitrogen (DON) in sewage treatment plant influent, determine its fate in biological nutrient removal (BNR) plants, and to evaluate and develop an appropriate treatment technology.
As a result of tightening effluent N licence requirements for sewage treatment plants, the dissolved organic nitrogen (DON) fraction has become extremely important. In many cases, the DON forms the major fraction of the effluent N, and is constraining further reductions in licence specifications, and in some cases it is the cause of failure to meet licence.
DON is refractory (un-biodegradable), very poorly characterised, its fate in conventional biological treatment processes not known, and its eventual impact on the environment unknown. Considering its importance, it is critical that these issues are addressed. This proposal intends to address some of them.
This project is an APA(I) PhD student project.Read moreRead less

The aim of this project is to develop a sustainable process for producing biodegradable polyhydroxyalkanoate (PHAs)polymers from an innovative aerobic-anaerobic biological wastewater treatment process, ?treating? high strength food industry effluent. These biopolymers offer enormous potential for use as renewable and biodegradable thermoplastics.
It is proposed to investigate two process configurations, namely the sequencing batch reactor and a continuous two step anaerobic-aerobic reaction system. These will be studied at bench-scale. The outcomes include:
1. Determination of the optimum microbial conditions and key growth
parameters for the production of PHA.
2. Optimisation of the process configuration, operating strategies
and operating conditions to maximise the
production of PHA.
3. Assessment of the influence of the feed composition (e.g. VFA)
on the PHA composition (PHB/PHV).
