Particle transport in turbulent non-Newtonian suspensions in self formed open channels. An improved understanding of the fundamentals of channel formation and the ability of channels to transport solids in either a natural or created environment will be of benefit to industries employing open channels (or flumes) or stacked tailings as part of their processes. This will lead to better design and operation with reduced water use and reduced volume of waste disposal. This research will build the ....Particle transport in turbulent non-Newtonian suspensions in self formed open channels. An improved understanding of the fundamentals of channel formation and the ability of channels to transport solids in either a natural or created environment will be of benefit to industries employing open channels (or flumes) or stacked tailings as part of their processes. This will lead to better design and operation with reduced water use and reduced volume of waste disposal. This research will build the scientific foundation for the design tools to more accurately predict the behaviour of tailings stacks. The mining industry will benefit from the improved management of their tailings disposal regimes, reduced water usage, lowered cost of disposal and reduced impact on the environment.Read moreRead less
Innovative strategy for salt management and water recovery from newsprint mill effluent using membrane processes. Newsprint mills are a major employer in regional Australia. The mills are located in environmentally sensitive areas, consume large quantities of water and return high levels of salt to the environment. To remain competitive the newsprint industry, like all industries in regional Australia must develop new strategies for water recycling and salt management. Successful execution of t ....Innovative strategy for salt management and water recovery from newsprint mill effluent using membrane processes. Newsprint mills are a major employer in regional Australia. The mills are located in environmentally sensitive areas, consume large quantities of water and return high levels of salt to the environment. To remain competitive the newsprint industry, like all industries in regional Australia must develop new strategies for water recycling and salt management. Successful execution of this project will minimize water consumption in newsprint production, mitigate the effects of increased sodicity in soils irrigated with mill effluent and accelerate the commercial development a hydrophobic microporous membrane for water recycling and salt removal in environmentally sensitive areas of inland Australia.Read moreRead less
Defining Fundamental Principles for the Design and Operation of Membrane Systems from Time-Varying Performance Analysis. To date, much of the process improvement for industrial application of membrane technology has revolved around polymer science based development of membrane materials and process and module changes resulting from the application of basic (often simplistic) engineering principles. While some future improvements may still come from these areas, the most dramatic advances are li ....Defining Fundamental Principles for the Design and Operation of Membrane Systems from Time-Varying Performance Analysis. To date, much of the process improvement for industrial application of membrane technology has revolved around polymer science based development of membrane materials and process and module changes resulting from the application of basic (often simplistic) engineering principles. While some future improvements may still come from these areas, the most dramatic advances are likely to be derived from the application of advanced engineering principles to this complex system. This project will integrate advanced CFD modelling and control principles for the design and operation of membrane systems in order to develop fundamental understanding that should lead to significant process improvements.Read moreRead less
Effect of cane sugar juice composition on scaling rate and scale composition in sugar mills. The Australia sugar industry produces 1100 GWh of renewable electricity annually, abating ~1.1 M tonnes of CO2-equivalent of greenhouse gases. This can be increased if the juice evaporation performance, which largely determines the energy efficiency of the sugar factory, can be improved through reduced fouling of evaporators. This project will investigate the effect of juice composition on fouling of sug ....Effect of cane sugar juice composition on scaling rate and scale composition in sugar mills. The Australia sugar industry produces 1100 GWh of renewable electricity annually, abating ~1.1 M tonnes of CO2-equivalent of greenhouse gases. This can be increased if the juice evaporation performance, which largely determines the energy efficiency of the sugar factory, can be improved through reduced fouling of evaporators. This project will investigate the effect of juice composition on fouling of sugar factory evaporators so that a model to predict scale type and scale propensity can be developed. This will enable the development of better scale control strategies, resulting in reduced energy usage and reduced usage of the hazardous and polluting chemicals required to remove scale.Read moreRead less
