Self-assembly of gelling biopolymer particles. Biopolymers provide a renewable source of structuring agents for a variety of potential uses in food, pharmaceutical and other applications that require bio-compatibility. Swollen biopolymer particles of sub-millimetre size are particularly useful as they combine macroscopic structure formation with an ability to flow and a desirable soft solid texture. Two limitations to the current utilisation of biopolymer particles are that they either cannot be ....Self-assembly of gelling biopolymer particles. Biopolymers provide a renewable source of structuring agents for a variety of potential uses in food, pharmaceutical and other applications that require bio-compatibility. Swollen biopolymer particles of sub-millimetre size are particularly useful as they combine macroscopic structure formation with an ability to flow and a desirable soft solid texture. Two limitations to the current utilisation of biopolymer particles are that they either cannot be predictably produced direct from a dried form, or if they are (e.g. cooked starch granules), there is a lack of scientific understanding that limits use of natural sources without subsequent chemical modification. This project will provide the science & technology to overcome these limitations.Read moreRead less
Understanding of structure development in drying droplets through the stickiness paradigm. The aims of this research are to develop a new model for multicomponent droplet drying. This model will provide predictions of conditions where composition variation exists in the drying particles. Validation of the model will be made using a novel instrument to measure the in-situ development of surface stickiness during drying.

The aims of this research are to develop a new model for multicomponent droplet drying. This model will provide predictions of conditions where composition variation exists in the drying particles. Validation of the model will be made using a novel instrument to measure the in-situ development of surface stickiness during drying. Stickiness is an important issue encountered during drying and handling of some key food and consumer materials. Currently, there is no technique to measure the evolution of stickiness during drying. Key outputs will include the model, the instrument, and the development of efficient methods to generate the multicomponent data.Read moreRead less
Wet granule mechanics and their influence on agglomeration behaviour and granulation processes. Granulation is a widely-used particle size enlargement process performed by spraying a liquid binder onto an agitated powder mass. It is currently impossible to quantitatively predict granule growth behaviour in terms of the fundamental properties of the particles and binder. This project will measure and model the deformation of granules and the strength of bonds formed between them and use this info ....Wet granule mechanics and their influence on agglomeration behaviour and granulation processes. Granulation is a widely-used particle size enlargement process performed by spraying a liquid binder onto an agitated powder mass. It is currently impossible to quantitatively predict granule growth behaviour in terms of the fundamental properties of the particles and binder. This project will measure and model the deformation of granules and the strength of bonds formed between them and use this information to predict their growth behaviour. Special attention will be given to the effects of strain-rate and particle morphology in granulation mechanics. Improvements in granulation technology will be of great benefit to food, pharmaceutical, agricultural, explosives and mining industries and opens the way to 'designer granulation' for special purposes.Read moreRead less
Optimising Fouling Control in Membrane Bioreactors. Membrane bioreactors (MBR) are growing in importance for wastewater treatment because they offer an alternative for producing higher effluent quality wastewater within a more compact space compared to conventional processes. However, due to the pumping and bubbling used to keep the membranes clear of foulants resulting from the biological processes in MBR's, controlling fouling incurs significant energy usage and costs. The proposal aims to red ....Optimising Fouling Control in Membrane Bioreactors. Membrane bioreactors (MBR) are growing in importance for wastewater treatment because they offer an alternative for producing higher effluent quality wastewater within a more compact space compared to conventional processes. However, due to the pumping and bubbling used to keep the membranes clear of foulants resulting from the biological processes in MBR's, controlling fouling incurs significant energy usage and costs. The proposal aims to reduce the costs of fouling control by understanding the optimal conditions to remove these depositions and improve the design of MBR modules, operating conditions and shear delivery in the membrane system.Read moreRead less
Macromolecular Fouling in Membrane Bioreactors. As the demands for domestic and industrial water increasing in Australia and overseas, membrane bioreactors (MBR) offer an alternative for producing higher effluent quality wastewater compared to conventional processes. However, aeration costs used to remove fouling deposits (which reduce the operating performance) need to be further minimised.

As the demands for domestic and industrial water increasing in Australia and overseas, membrane bioreactors (MBR) offer an alternative for producing higher effluent quality wastewater compared to conventional processes. However, aeration costs used to remove fouling deposits (which reduce the operating performance) need to be further minimised. The proposal aims to study fundamental mechanisms involve in the deposition of foulant components by using model systems of polysaccharides, proteins and microbial cells and comparing these with real MBR systems. The effect of bubbling varied gas compositions (air/H2S ratios) a novel approach in this study will be investigated to prevent or remove foulants in MBR systems. Read moreRead less
