Understanding the fluid mechanics of unsteady friction. Unsteady fluids flows are common in the fields of technology, engineering and physiology. This project brings together a multi-disciplinary team to consider the issue of unsteady friction. The research will focus on understanding the behaviour of water in pipes when subject to very fast transient events (such as those which cause the common problem of water hammer in the home).

Unsteady fluids flows are common in the fields of technology, engineering and physiology. This project brings together a multi-disciplinary team to consider the issue of unsteady friction. The research will focus on understanding the behaviour of water in pipes when subject to very fast transient events (such as those which cause the common problem of water hammer in the home). The project will produce new results that will be used by water engineers to design improved techniques for the rapid non-invasive identification of leaks in underground pipelines. As such our research has the potential to contribute huge savings to Australia's increasingly valuable water resources. Read moreRead less
Monitoring Desalination Membrane Fouling using Sodium Magnetic Resonance. Seawater desalination using membrane modules is critical technology for potable water access, however it faces significant challenges due to fouling. Sodium magnetic resonance techniques will be developed to non-invasively detect and image salt accumulation in these opaque membrane modules due to fouling.

Seawater desalination using membrane modules is critical technology for potable water access, however it faces significant challenges due to fouling. Sodium magnetic resonance techniques will be developed to non-invasively detect and image salt accumulation in these opaque membrane modules due to fouling. These data will first be used to improve our understanding of the unexplored interplay between fouling and detrimental salt accumulation in the modules (known as cake-enhanced concentration polarisation) and thus validate 3D simulations of this phenomenon. The ability to unambiguously detect salt accumulation in membrane modules will then be extrapolated to a non-invasive monitoring tool for membrane fouling in desalination facilities.Read moreRead less

Water distribution systems represent the single most important part of a society's infrastructure yet there are no comprehensive methods for detecting or assessing their physical condition. A suite of techniques (including those adapted from radar and sonar) for pro-active condition assessment will be developed in this research. The objective is to add significant intelligent and sophisticated numerical modelling capability to enable the non-invasive analysis of the transient pressure data, and to enable real-world application. This research will enable the continuous assessment of the physical condition of the entire water distribution system from an operations room resulting in significant savings.Read moreRead less

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
A Fourier approach to address low-frequency variability bias in hydrology. This project aims to develop a mathematical framework to better simulate the occurrence of sustained anomalies, such as droughts and long periods of flooding, into the future. These events increase water insecurity and result in loss of revenue, livelihoods and lives. Hydrological planning requires knowledge of how such sustained extremes will change in the future. Current alternatives for simulating such changes for futu ....A Fourier approach to address low-frequency variability bias in hydrology. This project aims to develop a mathematical framework to better simulate the occurrence of sustained anomalies, such as droughts and long periods of flooding, into the future. These events increase water insecurity and result in loss of revenue, livelihoods and lives. Hydrological planning requires knowledge of how such sustained extremes will change in the future. Current alternatives for simulating such changes for future climates are inadequate for catchment-scale planning to proceed. The project proposes a strategy for post-processing hydrological simulations of the future using an elegant frequency-domain approach. It expects to provide the tools needed to develop hydrologic infrastructure, such as water supply reservoirs, that secure our water resources for the generations to come.Read moreRead less

The increasing application of antimicrobial compounds in pharmaceutical and personal care products (PPCPs) requires improved understanding of their impact on the environment. Wastewater treatment plants (WWTPs) are a major removal process, however little is known about why certain PPCPs are removed during wastewater treatment and other are not. The project aims to study the fate of PPCPs and the spread of bacterial resistance in wastewater treatment. Studies will compare the effects of different treatment processes, operational conditions and environmental factors on the removal and treatment of PPCPs. The outcome will be the development of more sustainable WWTPs design and operation in terms of PPCPs removal.Read moreRead less
