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

Summary
Multi-purpose facility for enhanced complex ore beneficiation and waste material recycling. This facility will provide new separation equipment that exploits differences in physical-chemical characteristics and behaviour of multi-component minerals and industrial waste. The facility will be used to develop new methods to beneficiate or upgrade low grade mineral ores and materials. Research to be conducted at this facility will lead to improved and sustainable methods which will assist in process ....Multi-purpose facility for enhanced complex ore beneficiation and waste material recycling. This facility will provide new separation equipment that exploits differences in physical-chemical characteristics and behaviour of multi-component minerals and industrial waste. The facility will be used to develop new methods to beneficiate or upgrade low grade mineral ores and materials. Research to be conducted at this facility will lead to improved and sustainable methods which will assist in processing, recycling and reusing most of the non-metal and metal waste materials.Read moreRead less
