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
Feedback destabilising control of electro-osmotic flow for reducing fouling and enhancing productivity of membrane systems. This project aims to develop a new approach to improving the productivity of membrane systems. With over $9 billion worth of membrane-based desalination plants either in operation, under construction or being planned in Australia, the expected outcomes of this project will lead to significant social and economic benefit and provide greater water security.
Innovative hybrid membrane-based pretreatment strategies for remote community groundwater supplies. Innovative membrane-based strategies for the removal of particulate foulants from groundwaters prior to the removal of dissolved constituents via advanced techniques will be investigated in this project, with the goal of developing robust, integrated processes for the supply of potable water to remote communities.

Summary
Remediation of PFAS in current and legacy biosolids application sites. This project aims to develop novel immobilisation, adsorption and/or thermal destruction methods for biosolids, soil and groundwater in current and legacy per- and poly-fluroalkyl substance (PFAS) sites receiving biosolids. Biosolids generated during waste water treatment carry an unknown potential risk of soil and groundwater PFAS contamination, through their application in agriculture and rehabilitation sites. This project ....Remediation of PFAS in current and legacy biosolids application sites. This project aims to develop novel immobilisation, adsorption and/or thermal destruction methods for biosolids, soil and groundwater in current and legacy per- and poly-fluroalkyl substance (PFAS) sites receiving biosolids. Biosolids generated during waste water treatment carry an unknown potential risk of soil and groundwater PFAS contamination, through their application in agriculture and rehabilitation sites. This project will provide the first major investigation of the release, fate and remediation of perfluorinated compounds in relation to their environmental pathways through wastewater treatment plants in Australia. The data will be evaluated to determine if perfluorinated compounds should be further incorporated into Australian soil and water quality monitoring programs. The project will provide evidence of research advice and methodologies being successfully adopted by water industry end-users, government regulatory agencies and private remediation industries.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

The objective of this project is the discovery of novel methods for the treatment and reuse of water for both industrial and household applications. Improved treatment systems with the potential for water reuse offer significant improvements to our overall water management potential. The first part of the project is designed to focus on the study of hot bubble column evaporators for solute decomposition, sterilisation and the de-watering of heavily contaminated industrial wastewater. The second part would be based on the study of a suitable depth filter medium for the treatment of partially treated household sewage water. This is designed to form part of an on-site household sewage water treatment and reuse system which is currently being developed.Read moreRead less

Characterisation and Treatment of Reverse Osmosis Concentrates from Water Recycling Applications. Concentrates from reverse osmosis (RO) pose a considerable threat to both the environment but also the successful implementation of reverse osmosis as a technology. Naturally, the concentrate contains everything that the RO retains and hence contaminants such as viruses, organics such as pharmaceutically active compounds and hormones as well as nutrients and salinity.

Concentrates from reverse osmosis (RO) pose a considerable threat to both the environment but also the successful implementation of reverse osmosis as a technology. Naturally, the concentrate contains everything that the RO retains and hence contaminants such as viruses, organics such as pharmaceutically active compounds and hormones as well as nutrients and salinity. Treatment of such waste streams will enhance the health of receiving water bodies and reduce the risk of increased build up of contaminants if wastes are recycled into wastewater treatment plants. New ways to treat such contaminants will be explored, the efficiency and cost evaluated in the broader water cycle and sustainability framework.Read moreRead less
