Iron and phosphorus recovery from ferric precipitation sludge. To minimise health risks and environmental pollution, water and wastewater treatment processes often use iron salts to eliminate phosphate and other pollutants. This generates large amounts of chemical sludge that is typically sent to landfill. The benefits of this new process will be the recovery of both the iron, which can be reused in the process, and the phosphate, which is a key component in fertiliser. Since phosphate is a limi ....Iron and phosphorus recovery from ferric precipitation sludge. To minimise health risks and environmental pollution, water and wastewater treatment processes often use iron salts to eliminate phosphate and other pollutants. This generates large amounts of chemical sludge that is typically sent to landfill. The benefits of this new process will be the recovery of both the iron, which can be reused in the process, and the phosphate, which is a key component in fertiliser. Since phosphate is a limited natural resource with an increasingly high value, the recovery and recycling of this critical element in food production is highly important. The process will also avoid a large part of the sludge production and will make the water treatment processes more cost-effective.Read moreRead less

Summary
Integrated, scalable technology solutions for PFAS removal and destruction. 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 ....Integrated, scalable technology solutions for PFAS removal and destruction. 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
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). This project aims to comprehensively investigate the effectiveness of widely-used disinfection processes in controlling ARB/ARGs, determine the underly ....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). 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

Simultaneous dissolved methane and nitrogen removal. Direct anaerobic treatment of wastewater converts majority of organic matters in wastewater to methane, an energy source. However, up to 50% of the methane produced stays dissolved in wastewater. Its subsequent stripping to atmosphere in aerobic treatment not only causes significant loss of energy but also emission of a potent greenhouse gas. This project aims to develop a technology that not only avoids methane stripping but also enables its ....Simultaneous dissolved methane and nitrogen removal. Direct anaerobic treatment of wastewater converts majority of organic matters in wastewater to methane, an energy source. However, up to 50% of the methane produced stays dissolved in wastewater. Its subsequent stripping to atmosphere in aerobic treatment not only causes significant loss of energy but also emission of a potent greenhouse gas. This project aims to develop a technology that not only avoids methane stripping but also enables its beneficial use to enhance nitrogen removal, which is otherwise typically unsatisfactory due to the lack of organic carbon to support denitrification. The project will provide strong support to the Australian water industry in their endeavour to achieve energy- and carbon-neutral wastewater services.Read moreRead less
Reducing land and infrastructure requirements for water evaporation from biosludge through dry stacking. Melbourne's wastewater treatment plants have limited capacity in their evaporation pans to dry residual solids from wastewater treatment processes. This project will significantly improve the efficiency of new pans by providing an alternative operating method, dry stacking, which has delivered considerable benefits to the mineral industry.

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.
