Reuse of the treated wastewater from sewage treatment plants (STPs) has become significantly important in Australia due to dwindling water resources. The poor quality of the wastewater has limited its use for agriculture and aquaculture. This project aims to develop a solar nano-photocatalytic tertiary wastewater treatment process for disinfection and mineralization of the treated wastewater from STPs, making the wastewater suitable as a water resource. The newly developed nano-fibre catalysts and photocatalytic technology in the teatm will be used and further developed in this novel process. The research will focus on the water quality objectives in terms of technical reliability, and economic and environmental sustainability.Read moreRead less

The LASE process - a new approach to cost effective thin solar cells. This project aims to develop a process to produce a new type of single
crystalline silicon solar cell. The cell is made on very thin slices of silicon that are detached from a conventional high quality silicon wafer. The wafer is gradually consumed as successive slices are harvested from it. Substantially less silicon is used in each solar cell, which allows significant cost reductions.
