Summary
Efficient PFAS removal from urban wastewater using a novel two-step approach. This project aims to enhance the removal of per- and poly-fluroalkyl substances (PFAS) compounds from municipal wastewater by making two simple amendments to standard wastewater treatment plants. Magnetite nanoparticles will be added to the treatment process, which adsorb PFAS compounds and reduce them to acceptable environmental levels. The resulting sludge will be dried and ashed in a simple and novel self-sustaining ....Efficient PFAS removal from urban wastewater using a novel two-step approach. This project aims to enhance the removal of per- and poly-fluroalkyl substances (PFAS) compounds from municipal wastewater by making two simple amendments to standard wastewater treatment plants. Magnetite nanoparticles will be added to the treatment process, which adsorb PFAS compounds and reduce them to acceptable environmental levels. The resulting sludge will be dried and ashed in a simple and novel self-sustaining smoldering process which will render the captured PFAS to small ash, condensate and gaseous streams suitable for established destruction technologies. The project is expected to provide support to water utilities in achieving sustainable water treatment and result in environmental and social benefits to the community.Read moreRead less

"Circular Economy", via renewable energy and resource recovery. In a circular economy context, wastewater utilities are well placed to exploit the commercial potential of microalgae. Sewage treatment plants have an abundance of key nutrients required for algae growth, existing dewatering infrastructure that is suitable for harvesting algae and in some cases, existing anaerobic digestion infrastructure suitable for the conversion of microalgae to renewable energy in the form of biogas. This proje ...."Circular Economy", via renewable energy and resource recovery. In a circular economy context, wastewater utilities are well placed to exploit the commercial potential of microalgae. Sewage treatment plants have an abundance of key nutrients required for algae growth, existing dewatering infrastructure that is suitable for harvesting algae and in some cases, existing anaerobic digestion infrastructure suitable for the conversion of microalgae to renewable energy in the form of biogas. This project aims to upscale wastewater-based algae production that will enable increased renewable energy production via anaerobic digestion, for onsite thermal, electrical energy and upgraded liquefied natural gas.Read moreRead less
PFAS transport through landfill clay liners enhanced with proteins. Per- and polyfluoroalkyl substances (PFAS) are a group of environmentally persistent, man-made chemicals found likely to be carcinogenic in humans. Due to their non-stick, water and stain repellences, PFAS have long been used in everyday products (food wrappers, carpets, furniture etc.) which end up in landfills. As it is currently unknown how PFAS move through the various components of landfill barriers, their fate and transpor ....PFAS transport through landfill clay liners enhanced with proteins. Per- and polyfluoroalkyl substances (PFAS) are a group of environmentally persistent, man-made chemicals found likely to be carcinogenic in humans. Due to their non-stick, water and stain repellences, PFAS have long been used in everyday products (food wrappers, carpets, furniture etc.) which end up in landfills. As it is currently unknown how PFAS move through the various components of landfill barriers, their fate and transport has become a priority for the regulators of Australia’s landfill sites according to the Australian 2018 PFAS National Environmental Management Plan. This research will determine PFAS transport through common clay barriers enhanced with proteins which have been shown to be an excellent sorbent for PFAS.Read moreRead less
Energy Neutral Anthropogenic Nitrogen Management. This project aims to develop an innovative energy-neutral biological ammonium management strategy based on a novel anaerobic ammonia oxidation pathway.

This project aims to develop an innovative energy-neutral biological ammonium management strategy based on a novel anaerobic ammonia oxidation pathway. Ammonium-rich waste streams from urban and agricultural settings are a major cause of eutrophication and impose severe environmental burdens to human and ecological health. This project is expected to fundamentally change how we manage ammonium pollution, and will have immediate applicability to engineered bioreactors systems. This will provide significant benefits in supporting a wide range of industries that struggle with finding affordable and net-zero ways to manage ammonium wastes, providing an important step to reach global net-zero carbon emissions.Read moreRead less

This project aims to develop a suite of leading-edge biotechnology solutions to enable the cost-effective production of liquid chemicals from biogas. This will create a much stronger economic driver for biogas production from organic wastes, by significantly increasing the value of biogas compared to its current use for power generation. With a multi-disciplinary approach, the project will substantially advance the fundamental science in the exciting and highly valuable area of anaerobic microbial conversion of methane, the least understood process in the global carbon cycle. This transformational research has a strong potential to create a new biotechnology sector producing high-value chemicals from methane, and will propel Australia to the forefront of sustainable resources research.Read moreRead less

Biofilm-based solution for cost-effective high-quality drinking water. Approximately 90% of the drinking water in Australia is sourced from surface water bodies, which are naturally rich in nutrients and organic matter. This leads to the growth of cyanobacteria, which are known to be a major cause of taste and odour compounds and cyanotoxins. Climate change is causing increased cyanobacterial growth due to higher temperatures, exacerbating this existing challenge to water utilities.

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.

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
