Achieving Nitrite Shunt For Mainstream Sewage Treatment Using Human Waste. This project aims to develop a novel technology to achieve mainstream nitrogen removal from domestic sewage via nitrite shunt. Nitrite shunt can reduce energy consumption and promote energy recovery compared with the conventional nitrogen removal process. However, it is difficult to inactivate nitrite-oxidising bacteria, which is a key barrier for achieving nitrite shunt. By advancing the underpinning science and introduc ....Achieving Nitrite Shunt For Mainstream Sewage Treatment Using Human Waste. This project aims to develop a novel technology to achieve mainstream nitrogen removal from domestic sewage via nitrite shunt. Nitrite shunt can reduce energy consumption and promote energy recovery compared with the conventional nitrogen removal process. However, it is difficult to inactivate nitrite-oxidising bacteria, which is a key barrier for achieving nitrite shunt. By advancing the underpinning science and introducing a novel technology that innovatively harnesses a human waste, the project expects to remove the barrier. Expected outcomes will support the transformation of sewage treatment plants into net-zero energy generators. This should provide economic, environmental and energy benefits for Australia’s water and energy sectors.Read moreRead less
A Green Technology for Enhancing Resource Recovery from Sewage Sludge. This project aims to develop an innovative technology to recover valuable resource from sewage sludge by enhancing transformation of sewage sludge into high-value medium chain fatty acids and methane. Wastewater treatment generates large amounts of resource-rich sewage sludge. However, the poor biodegradability of sewage sludge is a key barrier that impedes the efficient resource recovery. By advancing the underpinning scienc ....A Green Technology for Enhancing Resource Recovery from Sewage Sludge. This project aims to develop an innovative technology to recover valuable resource from sewage sludge by enhancing transformation of sewage sludge into high-value medium chain fatty acids and methane. Wastewater treatment generates large amounts of resource-rich sewage sludge. However, the poor biodegradability of sewage sludge is a key barrier that impedes the efficient resource recovery. By advancing the underpinning science and introducing a novel technology that innovatively harnesses a human waste, the project expects to remove the barrier. Expected project outcomes will turn sewage sludge from an undesirable waste to a valuable resource. This should provide significant benefits for Australia’s renewable energy and resource sectors.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. 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 e ....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. 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
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
