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
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
Microbial fuel cells for nutrient recovery from source-separated urine. This project aims to reduce the strain on urban wastewater treatment plants by removing and recovering nutrients from water collected in residential and commercial buildings. Urban wastewater treatment plants in Australia are under pressure from increasing population and urbanisation, and there are also ever stricter environmental regulations on discharge of nutrients (mainly nitrogen and phosphorus) into receiving waters.

This project aims to reduce the strain on urban wastewater treatment plants by removing and recovering nutrients from water collected in residential and commercial buildings. Urban wastewater treatment plants in Australia are under pressure from increasing population and urbanisation, and there are also ever stricter environmental regulations on discharge of nutrients (mainly nitrogen and phosphorus) into receiving waters. With many plants operating close to capacity, water utilities may face large expenditure to increase the capacity of existing treatment facilities. This project proposes an alternative solution: decentralised removal and recovery of nutrients from urine separated at the source. It is planned that novel microbial fuel cell technology will be developed to deliver an economical solution, which will additionally generate valuable fertiliser as a by-product.Read moreRead less
Sustainable Water Reuse and Resource Recovery through Cost-Effective BNR. The recycling of treated wastewater effluents is needed to achieve water security, where very low nitrogen (N) and phosphorus (P) levels must be achieved for wastewater to be effectively recycled. This research investigates a more sustainable and cost-effective N&P removal process from wastewater, benefiting the environment and improving the viability of wastewater recycling. Phosphorus is a limited resource worldwide and ....Sustainable Water Reuse and Resource Recovery through Cost-Effective BNR. The recycling of treated wastewater effluents is needed to achieve water security, where very low nitrogen (N) and phosphorus (P) levels must be achieved for wastewater to be effectively recycled. This research investigates a more sustainable and cost-effective N&P removal process from wastewater, benefiting the environment and improving the viability of wastewater recycling. Phosphorus is a limited resource worldwide and will be effectively recovered in the process to be used as a fertiliser. This project develops wastewater treatment process tools, solutions and management strategies that addresses the current challenges of how optimal nutrient removal and recovery from wastewater is achieved, enabling water recycling and saving costs.Read moreRead less
Bio-electrochemical sulfate reduction and sulfur recovery without external carbon source. Highly acidic waterways and mining wastewaters create major environmental challenges in inland Australia. This project will use novel, solar driven biological processes to remove the acid and metals from these streams and enable beneficial reuse of the water and other resources recovered in the process.
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
Interactions between nanoparticles and bacteria. This project aims to understand how nanoparticles interfere with bacterial metabolism, and how these interactions lead to cell death, lysis and dispersal from biofilms. Intensive use of nanomaterials results in their continuously releases into the environment. While various nanoparticles have inhibitory and even toxic effects on microorganisms in ecosystems, the underlying mechanisms are not understood. This project will investigate model organism ....Interactions between nanoparticles and bacteria. This project aims to understand how nanoparticles interfere with bacterial metabolism, and how these interactions lead to cell death, lysis and dispersal from biofilms. Intensive use of nanomaterials results in their continuously releases into the environment. While various nanoparticles have inhibitory and even toxic effects on microorganisms in ecosystems, the underlying mechanisms are not understood. This project will investigate model organisms’ responses to nanoparticles at the cellular, enzymatic and gene expression levels. The findings are expected to help assess the immediate and long-term effect of nanoparticles on ecosystem health, for improved environmental management.Read moreRead less

Previously the major means of dealing with per- and poly-fluoroalkyl substances (PFAS) is by adsorption, to collect and remove PFAS from contaminated sites. However, PFAS still exist, non-degraded and waiting for destruction. Targeting slurry waste from current remediation / adsorption plants, this project aims to efficiently degrade PFAS by combining electrochemical oxidation with sono-chemistry to enhance degradation capacity, to accelerate PFAS desorption / transportation from slurry waste, to avoid electrode fouling and to detoxify PFAS. The expected outcome of this project is to clean up contaminated sites, including PFAS / precursors and other persistent organic pollutants, leading to significant environmental benefits.Read moreRead less
