Enhancing the productivity of wastewater desalination. Climate change is causing reduced rainfall over much of populated Australia. New technology to enable membrane desalination of wastewater treatment effluent will be developed to provide secure reliable water supplies for Australian (and international) urban and regional communities. Application of the technology to Western Treatment Plant at Werribee will provide up to 10 gigalitres/year of recycled water to the local agricultural, business ....Enhancing the productivity of wastewater desalination. Climate change is causing reduced rainfall over much of populated Australia. New technology to enable membrane desalination of wastewater treatment effluent will be developed to provide secure reliable water supplies for Australian (and international) urban and regional communities. Application of the technology to Western Treatment Plant at Werribee will provide up to 10 gigalitres/year of recycled water to the local agricultural, business and tourism precincts. The economy, community and environment will benefit due to reduced use of potable, river and ground water. Wide application of this technology to wastewater and brackish water will lead to similar benefits and an environmentally sustainable Australia.

A novel process for removing phosphorus microbiologically from wastewater. Australia is a water limited continent, and its rivers and lakes are priceless assets, but because of climatic conditions, these are especially sensitive to blooms of 'blue green algae'. Some are highly toxic, and water containing them is unsuitable for most purposes. Current technology for P removal requires constructing complex plant configurations, and most of these operate unpredictably and unreliably. This project ....A novel process for removing phosphorus microbiologically from wastewater. Australia is a water limited continent, and its rivers and lakes are priceless assets, but because of climatic conditions, these are especially sensitive to blooms of 'blue green algae'. Some are highly toxic, and water containing them is unsuitable for most purposes. Current technology for P removal requires constructing complex plant configurations, and most of these operate unpredictably and unreliably. This project will develop and fully evaluate a revolutionarily different alternative with a fully aerobic system, capable of being added onto the end of a conventional treatment plant, making protection of rivers and streams simpler and more feasible.

Optimising biodegradation and removal of organic and inorganic pollutants in wastewater using constructed wetlands. The urgency of water recycling is dictated by drying climate and rapid expansion of population in Australia. Constructed wetlands are environmentally-benign way to purify wastewater by removing inorganics and facilitating biodegradation of organic pollutants, thus producing recycled water that can be used in a variety of fit-for-purpose applications. This project will produce a dec ....Optimising biodegradation and removal of organic and inorganic pollutants in wastewater using constructed wetlands. The urgency of water recycling is dictated by drying climate and rapid expansion of population in Australia. Constructed wetlands are environmentally-benign way to purify wastewater by removing inorganics and facilitating biodegradation of organic pollutants, thus producing recycled water that can be used in a variety of fit-for-purpose applications. This project will produce a decision-support system for optimising wetland performance in removing inorganics and biodegrading organic pollutants from wastewater, thus enhancing water recycling and reuse in this drying continent of ours.Read moreRead less
Development of design guidelines for recycled plastic material and structural components. It is estimated that by 2010 over 1.2 million tonnes of plastic will be used annually by Australians of which only 3% is currently recycled. Preliminary testing of recycled plastic products has demonstrated their potential usefulness in structural engineering applications. However, the lack of guidelines suitable for advanced applications of recycled plastic is limiting the growth of this technology. This p ....Development of design guidelines for recycled plastic material and structural components. It is estimated that by 2010 over 1.2 million tonnes of plastic will be used annually by Australians of which only 3% is currently recycled. Preliminary testing of recycled plastic products has demonstrated their potential usefulness in structural engineering applications. However, the lack of guidelines suitable for advanced applications of recycled plastic is limiting the growth of this technology. This project aims to develop a set of rational guidelines for the testing, analysis and design of recycled plastic material and structural components that will enable the continued expansion of this technology, significantly reducing waste plastic.Read moreRead less
Photoelectrochemical control transport across a photoactive inorganic membrane fabricated by an in situ vapour phase hydrothermal method. Serious global fresh water shortage problems force us to recycle/reuse water. In Australia, this is an urgent issue due to our limited fresh water resources. Complete removal of biohazards (e.g., waterborne pathogens) from treated water is one of the most important aspects of safeguarding water recycling and has been the biggest obstacle for public acceptance. ....Photoelectrochemical control transport across a photoactive inorganic membrane fabricated by an in situ vapour phase hydrothermal method. Serious global fresh water shortage problems force us to recycle/reuse water. In Australia, this is an urgent issue due to our limited fresh water resources. Complete removal of biohazards (e.g., waterborne pathogens) from treated water is one of the most important aspects of safeguarding water recycling and has been the biggest obstacle for public acceptance. This project aims to tackle the issue by developing a highly efficient and effective new membrane technology that is capable of not just separating the biohazards from the source water but also in situ destroying them at the same time with low energy consumption and self cleaning features.Read moreRead less
An optimally integrated treatment process for food waste and wastewater to maximise sustainability in a decentralised treatment plant. Decentralised small scale treatment plants are required for remote communities, resort locations and 'rural residential' developments. This project has access to an operational plant in urban Brisbane serving 21 houses, the first development in urban Australia with full approval for an onsite treatment facility. The plant has been designed to treat an integrate ....An optimally integrated treatment process for food waste and wastewater to maximise sustainability in a decentralised treatment plant. Decentralised small scale treatment plants are required for remote communities, resort locations and 'rural residential' developments. This project has access to an operational plant in urban Brisbane serving 21 houses, the first development in urban Australia with full approval for an onsite treatment facility. The plant has been designed to treat an integrated kitchen waste and blackwater stream, with upstream anaerobic digestion that reduces the survival of wastewater pathogens and generates soluble organic carbon for the biological removal of nitrogen and phosphorous. The project will produce expertise in decentralised treatment systems, including the development of two PhD students in this area.Read moreRead less
