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
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.
As a result of tightening effluent N licence requirements for sewage treatment plants, ....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.
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
Integration of Sponge Based Technology and Membrane Bioreactor: A Sustainable Treatment System for Water Recycling. Clean, safe water is becoming scarce in Australia. Recycling water is considered a promising solution to this growing problem. It is therefore important to develop sustainable treatment technologies for it.

Clean, safe water is becoming scarce in Australia. Recycling water is considered a promising solution to this growing problem. It is therefore important to develop sustainable treatment technologies for it. Integrating sponge-based technology and membrane bioreactor systems will solve the most challenging problem of membrane fouling while producing high quality of recycled water from wastewater. The technology will maximize water resources, minimize waste and increase economic effectiveness and contributes direct benefits to the Nation in particular and to the world as a whole.Read moreRead less
Development of a Nitrogen Removal Technology to Integrate with the Novel ‘EnRec’ Energy Recovery Sewage Treatment Process. The aim of this project is to develop a nitrogen removal technology to integrate with the novel energy recovery sewage treatment process, EnRec. EnRec is presently being developed as part of a collaborative R&D activity between the partners, and is partly supported by a Queensland Government (QSEIF) grant which was awarded in November 2002.

The aim of this project is to develop a nitrogen removal technology to integrate with the novel energy recovery sewage treatment process, EnRec. EnRec is presently being developed as part of a collaborative R&D activity between the partners, and is partly supported by a Queensland Government (QSEIF) grant which was awarded in November 2002.
One important issue yet to be addressed is how to achieve nitrogen removal in the EnRec process. One of the major differences between the EnRec process and conventional sewage treatment technology is that the main process reactor is anaerobic, thus eliminating aeration costs and enabling methane production. However, anaerobic treatment processes do not provide significant nitrogen removal, and thus it will be necessary to integrate a nitrogen removal technology with the main energy recovery process. This is the aim of this project.
The project is an APA(I) PhD student project.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
