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
Defining Fundamental Principles for the Design and Operation of Membrane Systems from Time-Varying Performance Analysis. 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.

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

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

This project aims to develop management approaches to enable the use of anaerobic co-digestion — the conversion of organic wastes and wastewater sludge to biogas for electricity production. Anaerobic co-digestion has the potential to bring significant economic savings to water stakeholders and environmental benefits to communities. However, full-scale deployment faces fundamental challenges in terms of managing impacts on downstream processes (e.g. odour, dewaterability, biogas quality, and nutrient build-up). The analytical framework and analytics tool to be developed in this project by an interdisciplinary team with expertise in process engineering, biochemistry, analytical chemistry and analytics, is expected to enable water stakeholders to cost-effectively manage these impacts and thus realise the benefits of co-digestion.Read moreRead less
Electrocoagulation as a low-cost option for the continuous treatment of highly polluted wastewater. Water is a critically important 'raw material' with less than 0.01% of Earth's total supply being readily available. 'Once through' utilisation of this resource is no longer an acceptable industrial practise. Recycling/reuse of industrial wastewater must become the norm with economic pollutant recovery being seen as integral to the solution. The food/beverage industries are major water users.

Water is a critically important 'raw material' with less than 0.01% of Earth's total supply being readily available. 'Once through' utilisation of this resource is no longer an acceptable industrial practise. Recycling/reuse of industrial wastewater must become the norm with economic pollutant recovery being seen as integral to the solution. The food/beverage industries are major water users. Detailed scoping work in 2005 has identified electrocoagulation as a technically simple and economically viable option for this industry sector. Our industry partner is part of a global multi-national corporation within which successful wastewater treatment technology will be rapidly exploited and exported. Read moreRead less
