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
Improving Resilience of MCDI for Water Supply in Remote Communities . The AIM of this project is the development of robust, PV-powered water treatment units based on the emerging technology of Membrane Capacitive Deionisation (MCDI). The development of a more resilient approach to provision of potable water is particularly SIGNIFICANT to remote indigenous communities in central Australia where brackish groundwaters are unsuitable for use without prior treatment. EXPECTED OUTCOMES include develop ....Improving Resilience of MCDI for Water Supply in Remote Communities . The AIM of this project is the development of robust, PV-powered water treatment units based on the emerging technology of Membrane Capacitive Deionisation (MCDI). The development of a more resilient approach to provision of potable water is particularly SIGNIFICANT to remote indigenous communities in central Australia where brackish groundwaters are unsuitable for use without prior treatment. EXPECTED OUTCOMES include development of resilient MCDI units incorporating innovative control of the charging and discharging cycles using "smart” (machine learning enabled) Digital Twins of these units. These MCDI units will BENEFIT any community requiring removal of contaminants from brackish waters without the need for external mains power supply.Read moreRead less

Summary
Multifunctional polymers for combined algal inactivation and flocculation. Algal cells are harmful because they produce toxins and other undesirable metabolites. So, they are killed, aggregated, and separated from the water in distinct steps. Cell killing and aggregation are achieved via chemical dosing, which damages the cells and releases undesirable compounds. The aim is to develop multifunctional polymers that can simultaneously kill and aggregate the cells without causing cell damage. Addit ....Multifunctional polymers for combined algal inactivation and flocculation. Algal cells are harmful because they produce toxins and other undesirable metabolites. So, they are killed, aggregated, and separated from the water in distinct steps. Cell killing and aggregation are achieved via chemical dosing, which damages the cells and releases undesirable compounds. The aim is to develop multifunctional polymers that can simultaneously kill and aggregate the cells without causing cell damage. Additionally, this project provides insight into the mechanisms of polymer-induced cell damage and death that will be used to improve existing treatment methods. By combining treatment steps, chemical demand and costs will decrease, while there will be an increase in sustainability and benefits to the Australian water industry.Read moreRead less
Biofilm-based solution for cost-effective high-quality drinking water. Approximately 90% of the drinking water in Australia is sourced from surface water bodies, which are naturally rich in nutrients and organic matter. This leads to the growth of cyanobacteria, which are known to be a major cause of taste and odour compounds and cyanotoxins. Climate change is causing increased cyanobacterial growth due to higher temperatures, exacerbating this existing challenge to water utilities. This project ....Biofilm-based solution for cost-effective high-quality drinking water. Approximately 90% of the drinking water in Australia is sourced from surface water bodies, which are naturally rich in nutrients and organic matter. This leads to the growth of cyanobacteria, which are known to be a major cause of taste and odour compounds and cyanotoxins. Climate change is causing increased cyanobacterial growth due to higher temperatures, exacerbating this existing challenge to water utilities. This project proposes a novel biofilm-based approach for cost-effective drinking water treatment production. Our approach represents a simple retrofit to existing processes and drastically reduces the chemical dosing costs and improve climate resilience while ensuring the production of high-quality, safe drinking water.Read moreRead less
