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.

There is currently much concern about the release into the aquatic environment of oestrogenic and carcinogenic pollutants. Current conventional water treatment technologies are ineffective in removing them from our water supplies. This research proposes to investigate alternative water treatment technologies for the removal of these compounds of concern. The technologies to be investigated involve integrating membrane technology and titanium dioxide photocatalysis to produce a highly effective and efficient water treatment process. The effects of various parameters on degradation of the pollutants will be investigated and monitored using different analytical techniques.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
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

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
An innovative strategy for stormwater remediation and reduction of contaminant supply from catchments. Many urbanised harbours world-wide are polluted and the main source is stormwater.

Many urbanised harbours world-wide are polluted and the main source is stormwater. Currently, emphasis is to remove gross pollutants from stormwater using numerous devices scattered through the catchment. In a radical shift from traditional approaches, we will identify primary contaminant sources in the catchment for later targeted education and regulation and a single remediation device will remove most toxic substances in stormwater currently discharged to estuaries. Stormwater reuse will provide a new valuable urban resource. This paradigm shift in traditional stormwater strategy will ensure biodiversity and ecologically sustainable development of urbanised ports. Port Jackson is used as a test case.Read moreRead less
