Synthesis of Activated Carbon Supported Zero Valent Iron Nanoparticles and Application to Contaminant Degradation in Benthic Sediments. Sediment contamination is a major problem in harbours and estuaries around Australia. For example, in Sydney Harbour, a total fishing ban has been implemented as a result of excessive levels of dioxins and benzofurans in fish tissues.

Sediment contamination is a major problem in harbours and estuaries around Australia. For example, in Sydney Harbour, a total fishing ban has been implemented as a result of excessive levels of dioxins and benzofurans in fish tissues. There is also concern at the possibility of large scale contamination of Botany Bay as a result of historic industrial activity around the Bay. While dredging and on-land treatment of sediments is being adopted at the most severely contaminated sites, the cost of this approach is exorbitant. For sites where removal of contaminated sediments cannot be justified, the approach proposed in this study of a technology that entraps contaminants and enhances their in situ biodegradation is potentially a way forward.Read moreRead less

Novel methods of spill containment and debris mitigation on water surfaces. This project aims to develop a new technology for debris mitigation and spill containment, which isolates and stops spreading spills and redirect surface pollutants without using physical boundaries. Unexpected forced shutdowns of power plants, when floating debris blocks cooling water intake facilities, cause substantial operational risks, capital loss and affect the reliability of the electricity supply. The laboratory demonstration prototype, to be built as part of this project, could be scaled-up to demonstrate industrial applications such as the mitigation of blockages in water intakes of power plants and oil spill containment in estuaries. Anticipated outcomes are reduced operational risks in the electricity supply sector, and improved energy security.Read moreRead less
