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
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
Reducing direct greenhouse gas emissions from urban wastewater systems. This project aims to develop a systematic framework for water utilities to monitor and reduce direct greenhouse gas (GHG) emissions from wastewater systems. A standardised monitoring protocol will be developed to conduct an unprecedented nationwide sampling campaign. The obtained data, with microbial characterisation and mechanism analysis, will be used to develop novel models for accurate prediction of GHG emissions. Expect ....Reducing direct greenhouse gas emissions from urban wastewater systems. This project aims to develop a systematic framework for water utilities to monitor and reduce direct greenhouse gas (GHG) emissions from wastewater systems. A standardised monitoring protocol will be developed to conduct an unprecedented nationwide sampling campaign. The obtained data, with microbial characterisation and mechanism analysis, will be used to develop novel models for accurate prediction of GHG emissions. Expected outcomes include protocol to accurately monitor emissions, models to predict emission under various conditions, and mitigation guideline for typical plant configurations. The anticipated benefit is a significant reduction in GHG emissions from urban water industry and support it to meet net-zero-emission goal by 2050.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

Summary
Feasible quantification of greenhouse gas emitted from wastewater treatment. This project aims to develop an accurate and practical approach to quantify greenhouse gas (GHG) emissions from wastewater treatment. Australian water utilities have pledged to net-zero emissions. However, most utilities do not know its actual emissions due to lack of feasible quantification method. This project will apply an interdisciplinary approach via mechanism investigations, mathematical modelling, and field work ....Feasible quantification of greenhouse gas emitted from wastewater treatment. This project aims to develop an accurate and practical approach to quantify greenhouse gas (GHG) emissions from wastewater treatment. Australian water utilities have pledged to net-zero emissions. However, most utilities do not know its actual emissions due to lack of feasible quantification method. This project will apply an interdisciplinary approach via mechanism investigations, mathematical modelling, and field works to develop and validate a new feasible quantification method. This project will also advance knowledge on GHG emissions to guide quantification design. The outcomes will be translated into industry protocols and disseminated into industry. The outcomes provide timely support to water sector on its pathway to net-zero.Read moreRead less
