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
Nanobubbles for effective and energy efficient water treatment. 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 extrao ....Nanobubbles for effective and energy efficient water treatment. 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
Novel hybrid silica membranes for desalination. This project aims to produce high flux, highly stable ceramic membranes for use in desalination. This will result in novel, low energy desalination processes, delivering potable water at a greatly reduced cost.
Sustainable Hydrogen Production from Used Water. The project aims to address the pressing challenge of water scarcity in hydrogen production by developing an innovative approach of using used water as the feed for water electrolysis. The project will result in an in-depth understanding of the impacts of water impurities in used water on the performance and durability of water electrolysers, and develop guidelines for the design of highly durable water electrolysers and the operation and upgrade ....Sustainable Hydrogen Production from Used Water.

The project will result in an in-depth understanding of the impacts of water impurities in used water on the performance and durability of water electrolysers, and develop guidelines for the design of highly durable water electrolysers and the operation and upgrade of existing wastewater treatment plants. The project will advance the practical applications of water electrolysis for scalable and sustainable hydrogen production and help Australia secure a leading position in the global emerging hydrogen economy.Read moreRead less
Optimisation of nutrient removal, membrane fouling and sludge dewatering in hybrid coagulation/submerged membrane bioreactor treatment of wastewaters. Submerged membrane bioreactor technology for the treatment of wastewaters is now a competitive technology with small footprint and generally high quality of treated effluent. Despite this, challenges remain in ensuring low effluent nutrient concentrations, minimal membrane fouling and acceptable excess sludge dewaterability. Addition of iron or a ....Optimisation of nutrient removal, membrane fouling and sludge dewatering in hybrid coagulation/submerged membrane bioreactor treatment of wastewaters. Submerged membrane bioreactor technology for the treatment of wastewaters is now a competitive technology with small footprint and generally high quality of treated effluent. Despite this, challenges remain in ensuring low effluent nutrient concentrations, minimal membrane fouling and acceptable excess sludge dewaterability. Addition of iron or aluminium-based coagulant chemicals can assist but many uncertainties with regard to choice of chemical, optimal dosing arrangements and membrane bioreactor operating conditions remain. Experimental and computational studies targeted at improving understanding and optimising performance will be undertaken through collaborative studies by the UNSW and Tsinghua University (Beijing) research team.Read moreRead less
Novel and cost effective mixing technique for anaerobic digesters in municipal wastewater treatment plants. The mixing system and the models that will be developed in this project will be useful in improving the energy efficiency of anaerobic digesters operated in many towns and cities. These improvements will help to reduce greenhouse emissions significantly and also lead to reduced household water bills, as wastewater treatment costs will decrease.
Advancing passive greywater treatment at household scale. Water recycling is increasingly encouraged in drought stricken Australia. The project aims to develop more energy efficient and less chemically driven treatment using passive processes to recycle greywater. The project will help in establishing sustainable communities across Australia and establish Australia as a world leader in water sustainability.

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

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
