This project aims to deliver a ready-to-deploy and scalable modular technology that is capable of removing poly- and per-fluoroalkyl substances (PFAS) from a variety of water sources, including groundwater and surface waters, to make them virtually PFAS-free and therefore safe for human consumption. The concept draws on recent advances in water treatment and electrochemistry that is based on ion exchange, nanofiltration and advanced oxidation. A risk-based framework will be developed to deliver fit-for-purpose solutions at minimal cost for stakeholders and taxpayers. This project is expected to benefit the residents who live in the vicinity of contaminated waterways or consume water from polluted sources.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

This project aims to produce new knowledge for developing ozone nanobubbles as a technological option for the water industry where commercially suitable technologies are unavailable. Australian water utilities have identified two key challenges: destruction of micropollutants and natural organic matter in recycled and reservoir water, respectively. New knowledge from the project will allow these water utilities to utilise the extraordinary properties of nanobubbles and the strong oxidation capability of ozone for effective and energy efficient water treatment. Tech-transfer to the industry is guaranteed through a scientifically designed pilot plant for benchmarking against the current state of the art ozonation process and reverse osmosis.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.

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
Novel disinfection to combat antibiotic resistance . Control of antimicrobial resistance in water is critical. Disinfection in water and wastewater treatment plants is a vital barrier against antibiotic resistant bacteria (ARB); however, it is less effective in controlling- and may even facilitate the spread of antibiotic resistance genes (ARGs).

Control of antimicrobial resistance in water is critical. Disinfection in water and wastewater treatment plants is a vital barrier against antibiotic resistant bacteria (ARB); however, it is less effective in controlling- and may even facilitate the spread of antibiotic resistance genes (ARGs). This project aims to comprehensively investigate the effectiveness of widely-used disinfection processes in controlling ARB/ARGs, determine the underlying mechanisms, and identify optimal treatment conditions. This project also aims to develop a novel, cost-effective and environmentally friendly disinfection process for efficient ARGs destruction, thus significantly strengthening Australia’s capacity to prevent the spread of antibiotic resistance.Read moreRead less

Climate change is driving a proliferation of nuisance and harmful algal blooms in our water supply systems, which urgently require cost efficient and effective control strategies. Paradoxically, algal biotechnology is a growth industry with application in food, agriculture and energy; realising this potential requires state-of-the-art technology to optimise production, harvesting and extraction. The aim of this proposal is to develop cutting edge technology that uses cold plasma activated microbubbles to control algal populations. We propose that by tuning the plasma composition, this technology could both selectively disrupt and destroy algal matter and enhance algal cell growth, benefiting both water and biotechnology industries.

Mitigation of silica nanoparticle scaling in water treatment. This project aims to develop strategies to mitigate silica scaling at coal seam gas (CSG) water treatment facilities. CSG is adsorbed to the surface of coal along fractures and cleats and released when pressure is reduced by removal of groundwater, which has chemistry specific to the region from which it is extracted. Desalination of produced water is severely impacted by mineral scaling on reverse osmosis membranes. This project will ....Mitigation of silica nanoparticle scaling in water treatment. This project aims to develop strategies to mitigate silica scaling at coal seam gas (CSG) water treatment facilities. CSG is adsorbed to the surface of coal along fractures and cleats and released when pressure is reduced by removal of groundwater, which has chemistry specific to the region from which it is extracted. Desalination of produced water is severely impacted by mineral scaling on reverse osmosis membranes. This project will consider silica and silica-rich nanoparticles in concert with cations and organics, with the aim of better managing cations so to facilitate nanoparticle lubrication. Project outcomes may include more productive use of assets, improved pre-treatment infrastructure to support reverse osmosis operation, and the environmental benefits of reduced chemical waste and increased water recovery.Read moreRead less

The solar-steam desalination technology offers an ideal strategy to utilize solar light as the energy source for desalination and water purification to produce affordable clean water. Photothermal materials play a key role in the desalination system to convert sunlight to heat and subsequently evaporate the saline water to generate steam as clean water. However, salt crystallization on the photothermal material surfaces severely limits the performance of the materials and clean water production. Solving this problem could accelerate the commercialisation and application of this technology, which will benefit millions of people worldwide.Read moreRead less

This project aims to address an important limitation in the ability to monitor performance of advanced oxidation processes used to treat recycled water for drinking. The project will be conducted using a novel pilot system, designed to facilitate flexible operation and detailed monitoring. Through carefully designed experiments, observed operational parameters will be related to treatment performance for a range of contaminants. An expected outcome is the development of a framework to provide validation of process performance relationships and ongoing performance monitoring for use by water utilities and regulatory agencies that oversee their operations. This highly practical framework for validation and performance monitoring of an advanced water treatment process should result in improved viability of water recycling projects, increased urban water supply security and enhanced protection of public health.Read moreRead less
