The HDR student must be graduates in Engineering or Physics and should be particularly interested in the measurement of individual bubble properties using acoustic techniques. They will have a strong academic background and ideally have experience and a desire to work in an experimental setting. Experience in water and waste water treatment, mineral flotation and/or the use of acoustic methods is desirable, as well as an understanding and experience in practical and industrial applications in the water or resource industries.

Dissolved air flotation (DAF), used in drinking and waste water applications, has tremendous potential for resource extraction and waste management in mining, pulp, paper, food processing and biotechnology applications. Effective separation is dependent on the strong attachment of microbubbles to particles; however, interactions are difficult to quantify and simulate, thus DAF designs use empirical models which are not transferable to other industries and hinder innovation. Hence, this project will examine interactions between bubbles and particles in DAF systems for a range of configurations. This will be achieved via the development of novel in situ acoustic monitoring and state-of-the-art visualisation techniques. The knowledge gained from the project will equally be applicable to the mineral industry, the bedrock of the Australian economy.
