Novel plastics using renewable signal chemistry to remove bacteria in water. This project plans to develop synthetic plastic surfaces that continuously generate nitric oxide to deter the formation of biofilms. Plastic surfaces exposed to aqueous environments rapidly become covered by a film of bacteria, which can cause infection. Trace levels of generated nitric oxide can combat this problem by breaking up existing bacterial biofilms. Current research has developed plastics that continuously gen ....Novel plastics using renewable signal chemistry to remove bacteria in water. This project plans to develop synthetic plastic surfaces that continuously generate nitric oxide to deter the formation of biofilms. Plastic surfaces exposed to aqueous environments rapidly become covered by a film of bacteria, which can cause infection. Trace levels of generated nitric oxide can combat this problem by breaking up existing bacterial biofilms. Current research has developed plastics that continuously generate nitric oxide, but not for extended periods of time. This project’s approach is significant because it avoids bacterial resistance to the nitric oxide treatment. Applications of this technology may include removing biofilms from environments such as water filtration devices and consumable medical surfaces.Read moreRead less
Mitigation of silica nanoparticle scaling in water treatment. This project aims to develop strategies to mitigate silica scaling at coal seam gas (CSG) water treatment facilities. CSG is adsorbed to the surface of coal along fractures and cleats and released when pressure is reduced by removal of groundwater, which has chemistry specific to the region from which it is extracted. Desalination of produced water is severely impacted by mineral scaling on reverse osmosis membranes. This project will ....Mitigation of silica nanoparticle scaling in water treatment. This project aims to develop strategies to mitigate silica scaling at coal seam gas (CSG) water treatment facilities. CSG is adsorbed to the surface of coal along fractures and cleats and released when pressure is reduced by removal of groundwater, which has chemistry specific to the region from which it is extracted. Desalination of produced water is severely impacted by mineral scaling on reverse osmosis membranes. This project will consider silica and silica-rich nanoparticles in concert with cations and organics, with the aim of better managing cations so to facilitate nanoparticle lubrication. Project outcomes may include more productive use of assets, improved pre-treatment infrastructure to support reverse osmosis operation, and the environmental benefits of reduced chemical waste and increased water recovery.Read moreRead less
Development and Modellling of Advanced Coagulation and Oxidation Processes. The success of this program will help place Australia at the forefront of water quality control and management research. It will address concerns with managing and treating waters of changing characteristics due to climate change. In addition to the socio benefits, project success will also impart economic benefits to the nation through (i) fabricating new hybrid coagulants, that are versatile with enhanced performance ....Development and Modellling of Advanced Coagulation and Oxidation Processes. The success of this program will help place Australia at the forefront of water quality control and management research. It will address concerns with managing and treating waters of changing characteristics due to climate change. In addition to the socio benefits, project success will also impart economic benefits to the nation through (i) fabricating new hybrid coagulants, that are versatile with enhanced performance for removing NOM, and possess antimicrobial properties (ii) developing a new energy efficient photocatalysis technology.The proposed research will expand the knowledge base in this area and increase Australia’s international profile as a global leader in developing cutting-edge cost effective water resource technologies.Read moreRead less
Multi-scale strategy to manage chloramine decay and nitrification in water distribution systems. The generation of knowledge and technologies in preventing chloramine decay would greatly benefit the Australian water industry. The success of the project would provide the highest possible quality of water, both economically and reliably, giving public assurances of microbiological compliance and safe drinking water.
