Optimising nanofiltration and reverse osmosis filtration processes for water recycling: effects of fouling and chemical cleaning on trace contaminant removal. In Australia, water recycling is considered a principal measure to manage the current ongoing water shortage and to better protect the environment.

In Australia, water recycling is considered a principal measure to manage the current ongoing water shortage and to better protect the environment. Membrane filtration processes play important roles in the treatment of reclaimed municipal wastewater. However, there is very limited knowledge regarding the reliability of such processes in removing trace contaminants from recycled water, which may result in unintended health consequences. This research will lead to a comprehensive understanding of the removal process of such contaminants by membrane filtration. Consequently, the likely avenue of risk can be eliminated and the treatment process can be optimised to achieve economic savings and environmental protection.Read moreRead less

Monitoring of trace pollutants in water is expensive, laborious and requires sophisticated analytical techniques. Building on the research team's new technique, which uses a phyto-tox test based on photosynthesis inhibition in algae, this study will further develop and evaluate methodologies and applications for measuring phyto-toxic chemicals in environmental water samples. The project aims specifically to:
- identify suitable algae, sensitive to phyto-toxic chemicals
- determine dose-response for priority pollutants in selected algae
- evaluate critical parameters affecting measurements
- develop pre-concentration techniques.
The outcomes will provide the first on-site trace pollutant testing method allowing more effective management of water pollution

Sources, fate and exposure pathways for emerging persistent organic pollutants in Australia. Brominated flame retardants and perfluorinated chemicals have received much attention from media and environmental groups. They accumulate in biota and humans and levels are shown to be increasing. It is proposed they be included in the global treaty on persistent organic pollutants (POPs), recently ratified by Australia.

Brominated flame retardants and perfluorinated chemicals have received much attention from media and environmental groups. They accumulate in biota and humans and levels are shown to be increasing. It is proposed they be included in the global treaty on persistent organic pollutants (POPs), recently ratified by Australia. This project aims to determine sources, fate and exposure pathways for these chemicals with an emphasis on exposure to infants. This will provide information for risk assessment development and more effective management of these chemicals. Furthermore, the study's approach and results will contribute to a rationalization of the issues related to emerging POPs. Read moreRead less
