Cost effective treatment system for stormwater harvesting for medium scale developments. Stormwater harvesting is central to the integrated water cycle management approach now being formally endorsed by all tiers of governments as the best way to manage our water resources. Despite its immense potential, stormwater harvesting in urban centres throughout Australia is largely limited to household rainwater tanks.

Stormwater harvesting is central to the integrated water cycle management approach now being formally endorsed by all tiers of governments as the best way to manage our water resources. Despite its immense potential, stormwater harvesting in urban centres throughout Australia is largely limited to household rainwater tanks. By developing economical and efficient treatment systems suitable for medium density developments, this project will maximise the resource value of stormwater, and reduce demand on water supply systems. The project will lead to the development of medium sized communities within larger urban centres that maximises its use of stormwater for water needs.Read moreRead less
Ammonia recovery from wastewaters using flow electrode-membrane systems. This project aims to develop an innovative approach to the recovery of ammonia from dilute wastewaters using coupled-flow electrode-membrane technologies that also enable energy recovery. The outcome of the project is expected to minimise damage to, and develop solutions for, restoration and remediation of, soil, fresh and potable water, urban catchments and marine systems, and significantly improve the environmental impact ....Ammonia recovery from wastewaters using flow electrode-membrane systems.

Solar detoxification of wastewater: Bactericidal and photocatalytic activities of titania-based compounds in an externally-irradiated bubble column immobilized reactor. Light-assisted treatment is one of the most attractive methods for wastewater reclamation - a major issue for Australia with limited fresh water resources. However, commercial exploitation is hindered by inability to harness sunlight and poor photoreactor design. This proposal deals with the development of Co-titania photocatalys ....Solar detoxification of wastewater: Bactericidal and photocatalytic activities of titania-based compounds in an externally-irradiated bubble column immobilized reactor. Light-assisted treatment is one of the most attractive methods for wastewater reclamation - a major issue for Australia with limited fresh water resources. However, commercial exploitation is hindered by inability to harness sunlight and poor photoreactor design. This proposal deals with the development of Co-titania photocatalyst activatable by visible light to effect organic degradation and bacterial sterilization simultaneously at room temperature. The new reactor permits in-situ separation of the solid catalyst from treated liquid thus ensuring continuous production of recyclable water. The huge economic returns of solar-operated mobile or stationary wastewater unit from local and international markets are obvious.Read moreRead less
Geo-hydrodynamic modelling and estuarine evolution. We have accumulated considerable knowledge of the geomorphology, sedimentology and hydrodynamics of estuarine systems in southeastern Ausralia. This project represents the first rigorous attempt to combine these diverse factors to provide a process-based mathematical model of long- to medium-term sedimentation that can be used for environmental management. To be predictive the model has to use documented changes in the sedimentation histories o ....Geo-hydrodynamic modelling and estuarine evolution. We have accumulated considerable knowledge of the geomorphology, sedimentology and hydrodynamics of estuarine systems in southeastern Ausralia. This project represents the first rigorous attempt to combine these diverse factors to provide a process-based mathematical model of long- to medium-term sedimentation that can be used for environmental management. To be predictive the model has to use documented changes in the sedimentation histories of different estuary types over the past 8000 years in order to predict their evolution over the next 1000 years. The models that are developed can be applied to estuarine systems both nationally and internationally.Read moreRead less

Direct reduction of mixed oxides at lower temperatures: a novel approach to produce lightweight ferrous alloys. This project will develop a novel approach to directly produce aluminium based ferrous alloys at temperatures 550C-950C lower than conventional processes. The simultaneous reduction of mixed oxides will lower the energy requirements for producing ferroalloys, enhance cost effectiveness and reduce greenhouse gas emissions.
Lower temperature ironmaking: macro and atomic-level understanding of accelerated carburisation of reduced iron. This project will gain an understanding of how iron-oxide can be simultaneously reduced and carburised in ironmaking, including the kinetics and associated mechanisms of the reaction with waste coal/iron-ore fines. This will be the key to developing a relatively low-temperature process, with significant savings in energy consumption.
Reactive oxygen species generation by zerovalent silver nanoparticles; implications to toxicity and contaminant degradation. Nanoparticulate silver is now being used for the purification of drinking water yet many questions remain concerning its mode of purifying action. Here we investigate the generation of reactive oxygen species (ROS) by nanoparticulate silver and examine the relationship between ROS generation and the purifying action of "nano-silver".
