Degradation of Trace Contaminants Using Sonochemistry and Peroxide Scavenging Advanced Oxidation Processes. Sonochemical degradation of hazardous organic compounds in aqueous solution has been examined extensively in recent years and found to be an effective means of waste treatment however the scavenging of hydroxyl radicals by the relatively high concentrations of hydrogen peroxide produced limits the amount of reactive radicals accessible to target molecules. In this project we will investiga ....Degradation of Trace Contaminants Using Sonochemistry and Peroxide Scavenging Advanced Oxidation Processes. Sonochemical degradation of hazardous organic compounds in aqueous solution has been examined extensively in recent years and found to be an effective means of waste treatment however the scavenging of hydroxyl radicals by the relatively high concentrations of hydrogen peroxide produced limits the amount of reactive radicals accessible to target molecules. In this project we will investigate, by both experimental and computational means, options for the regeneration of hydroxyl radicals through use of hydrogen peroxide. Methods of particular interest include use of Fenton's reagent and ozone.Read moreRead less
Photodesorption Phenomena and Photoreactive Nanosorbent Materials for Water and Wastewater Purification. Introducing more efficient production of drinking water and wastewater treatment methods for reuse is important to address increasing water scarcity in Australia. The proposed project will develop a water purification technology to remove pollutants using a recently discovered process. This process offers simple and affordable operation that is clean, robust and requires minimal attention. Th ....Photodesorption Phenomena and Photoreactive Nanosorbent Materials for Water and Wastewater Purification. Introducing more efficient production of drinking water and wastewater treatment methods for reuse is important to address increasing water scarcity in Australia. The proposed project will develop a water purification technology to remove pollutants using a recently discovered process. This process offers simple and affordable operation that is clean, robust and requires minimal attention. The technology is particularly suitable for small-scale applications in rural and remote areas, and has significant export potential. The project will strengthen established links between Australian and Korean research centres through the production of improved nanomaterials, and the development of the novel water purification technologyRead moreRead less
A pilot study to demonstrate the use of 15N tracers for determining the flow of nitrogen through lower food webs. This project will have a significant impact on the way wetland wastewater treatment and reuse (WWTR) facilities are constructed in the future. Addressing the key biochemical issues to WWTR systems this study will facilitate improved construction design and management to optimise treatment performance. As National Priority One Area, sustainable water use and the efficiency of WWTR sys ....A pilot study to demonstrate the use of 15N tracers for determining the flow of nitrogen through lower food webs. This project will have a significant impact on the way wetland wastewater treatment and reuse (WWTR) facilities are constructed in the future. Addressing the key biochemical issues to WWTR systems this study will facilitate improved construction design and management to optimise treatment performance. As National Priority One Area, sustainable water use and the efficiency of WWTR systems is fundamental to our economic and social development. The results gleaned from this study will assist in the future design of WWTR systems that will be transferable outside the local study area and as such be of potential benefit both Nationally and internationally.Read moreRead less
