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

Controllable Synthesis of Defects in Catalysts for Electrocatalysis . This project aims to address the most critical issue of electrocatalysis: identification of active sites for carbon-based metal free catalysts (CMFCs). Through the development of new methodologies, this proposal will, for the first time, controllably synthesise the vacancy defects that are the major active sites for CMFCs. The expected outcomes from this project include in-depth understanding of the fundamentals of electrocata ....Controllable Synthesis of Defects in Catalysts for Electrocatalysis . This project aims to address the most critical issue of electrocatalysis: identification of active sites for carbon-based metal free catalysts (CMFCs). Through the development of new methodologies, this proposal will, for the first time, controllably synthesise the vacancy defects that are the major active sites for CMFCs. The expected outcomes from this project include in-depth understanding of the fundamentals of electrocatalysis: the reactivity of active sites and the catalytic performance with the number of active sites; which will not only significantly advance knowledge but also achieve breakthrough technologies that greatly benefit to the society and economy both for Australia and worldwide.Read moreRead less
Simultaneous dissolved methane and nitrogen removal. Direct anaerobic treatment of wastewater converts majority of organic matters in wastewater to methane, an energy source. However, up to 50% of the methane produced stays dissolved in wastewater. Its subsequent stripping to atmosphere in aerobic treatment not only causes significant loss of energy but also emission of a potent greenhouse gas. This project aims to develop a technology that not only avoids methane stripping but also enables its ....Simultaneous dissolved methane and nitrogen removal. Direct anaerobic treatment of wastewater converts majority of organic matters in wastewater to methane, an energy source. However, up to 50% of the methane produced stays dissolved in wastewater. Its subsequent stripping to atmosphere in aerobic treatment not only causes significant loss of energy but also emission of a potent greenhouse gas. This project aims to develop a technology that not only avoids methane stripping but also enables its beneficial use to enhance nitrogen removal, which is otherwise typically unsatisfactory due to the lack of organic carbon to support denitrification. The project will provide strong support to the Australian water industry in their endeavour to achieve energy- and carbon-neutral wastewater services.Read moreRead less
