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
Particle classification using a ferrofluid in a non uniform magnetic field. The separation of micron size components of suspensions according to the size and density of the particles is presently an intractable problem. However, by using a magnetized ferrofluid it should be possible to generate unique particle trajectories for each combination of particle size and density. This study investigates the potential of this strategy for separating such particles, laying the foundation for new small-sc ....Particle classification using a ferrofluid in a non uniform magnetic field. The separation of micron size components of suspensions according to the size and density of the particles is presently an intractable problem. However, by using a magnetized ferrofluid it should be possible to generate unique particle trajectories for each combination of particle size and density. This study investigates the potential of this strategy for separating such particles, laying the foundation for new small-scale diagnostic "lab-on a chip" technology that could be used in biotechnology to study whole blood, or in mineral processing to control energy intensive ball mills for mineral particle liberation.Read moreRead less
The Development of New Carrier Technologies for Spray-Dried Fruit Extracts. This project aims to develop new carrier techniques for spray drying fruit extracts based on the use of natural fibres, with the aim of overcoming a key problem in the operation of spray dryers for producing powders, the deposition of particles on walls. Carriers are non-sticky materials that effectively dilute the stickiness of any materials. The significance is that it will use waste products from fruit processing (th ....The Development of New Carrier Technologies for Spray-Dried Fruit Extracts. This project aims to develop new carrier techniques for spray drying fruit extracts based on the use of natural fibres, with the aim of overcoming a key problem in the operation of spray dryers for producing powders, the deposition of particles on walls. Carriers are non-sticky materials that effectively dilute the stickiness of any materials. The significance is that it will use waste products from fruit processing (the fibres from skins) to overcome this problem, and it will also be possible to dry sticky materials using material from the fruit itself, rather than additives such as maltodextrin.Read moreRead less
Designing the surface and structural properties of MFI zeolite membranes for low energy ion-selective desalination. Desalination is being established in response to climate change and growing demands on existing supplies. Fresh water from infinitely abundant ocean sources using little energy input will benefit communities by providing affordably a vital resource with minimal greenhouse gas emissions.

Desalination is being established in response to climate change and growing demands on existing supplies. Fresh water from infinitely abundant ocean sources using little energy input will benefit communities by providing affordably a vital resource with minimal greenhouse gas emissions. Fresh water from current desalination costs $2 per kl, being a major expense for a vital resource normally $0.2 per kl. As energy input accounts for half of the desalination cost, the smart ion-selective membrane to be developed in this project has the capability to reduce desalinated water price by 50%. Such an advancement derived from fundamental material properties is a novel contribution to both science and membrane desalinationRead moreRead less

The management of greenhouse and other acid gas emissions is vital to a sustainable future of both the economy and the ecosystem. This project will develop novel nano-materials for gas separation by tethering organic functional groups to the surface of porous inorganic supports. These materials offer the promise of combining the high selectivity and high capacity of liquid phase absorption systems with the rapid transport rates of gas-solid adsorption systems. Success would open up several new possibilities for reengineering gas separation systems based on the use of these materials in solution, as solid phase adsorbents (pressure swing adsorption) and/or as permeselective gas membranes.Read moreRead less

Summary
Advanced characterisation of organics and biopolymers in water and wastewater treatment. Although membrane technology is increasingly used for water production, wastewater treatment and reclamation, fouling by complex bio-organics is a major limitation. The liquid chromatography-organic carbon detection and the Flow FFF equipments give detailed analyses of the complex organics, thereby helping to understand the fouling and organic removal mechanisms allowing process optimisation.

The liquid chromatography-organic carbon detection and the Flow FFF equipments give detailed analyses of the complex organics, thereby helping to understand the fouling and organic removal mechanisms allowing process optimisation. The availability of these equipments will ramatically improve the quality of a number of research projects currently funded and being developed in Australia. This equipment would provide necessary infrastructure to keep Australian researchers world leaders in this research field (one of Australian top research priorities) and attract national and international collaborations.Read moreRead less

Foam fractionation has a number of immediate applications in mineral and food processing but its most exciting potential is as low cost alternative for recovering and purifying high value biosurfactants. These are materials used to stabilise interfaces in living systems, and can be used as antibiotics and antiviral agents. The affinity for biosurfactants to collect at an interface suggests that foam fractionation is an ideal process to concentrate valuable products. Clearly, a cost-effective and reliable method of enriching streams of biosurfactants will make their use even more attractive and will engender the development of more novel biomaterials, such as pepfactants.Read moreRead less
