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

Summary
PFAS source zone remediation by foam fractionation and in situ fluidisation. This project aims to develop two methods for the in situ remediation of per- and poly-fluroalkyl substances (PFAS) contamination, downhole foam fractionation for in situ groundwater treatment, and in situ fluidisation for soil treatment, both separately and in combination. Using these methods, PFASs will be removed in the form of a foam, which will be extracted as a liquid concentrate. These techniques could enable PFAS ....PFAS source zone remediation by foam fractionation and in situ fluidisation. This project aims to develop two methods for the in situ remediation of per- and poly-fluroalkyl substances (PFAS) contamination, downhole foam fractionation for in situ groundwater treatment, and in situ fluidisation for soil treatment, both separately and in combination. Using these methods, PFASs will be removed in the form of a foam, which will be extracted as a liquid concentrate. These techniques could enable PFAS removal efficiencies of greater than 90%, providing entirely new methods for the aggressive removal of PFAS from contaminated source zones. This project will enable the rapid removal of the bulk of the PFAS present in soils and groundwater and reduce the potential for further spreading.Read moreRead less
Improving the Durability and Performance of Hollow Fibre Membranes with Nanocomposite and Inorganic/organic Hybrid Materials. Water is a critical resource for societies worldwide and Australia is one of the driest nations on Earth. Options to treat ‘used’ or lower quality waters for reuse are becoming a necessity.

Water is a critical resource for societies worldwide and Australia is one of the driest nations on Earth. Options to treat ‘used’ or lower quality waters for reuse are becoming a necessity. This project aims to implement advanced nanotechnology solutions to improve performance characteristics of widely adopted water treatment membranes, which have the potential to reduce water treatment costs in Australia. This is made possible by the collaboration with Australia's largest manufacturer of water treatment membranes. The outcomes will lead towards a lower maintenance water treatment technology available to communities, at lower cost. The application of such a technology will span from local small scale to major installations worldwide.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.

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
Fate of PAPs and short-chain PFAS in biosolids amended soils. Biosolids generated during wastewater treatment contain PFAS which are persistent, bioaccumulative and toxic. Application of biosolids to agricultural land may result in soil, groundwater and surface water PFAS contamination via leaching and run-off and pose unknown potential risk to soil health, crops and beneficial biota. This study aims to generate novel knowledge on the PFAS fate in biosolid amended soils, crops and toxicity to ke ....Fate of PAPs and short-chain PFAS in biosolids amended soils. Biosolids generated during wastewater treatment contain PFAS which are persistent, bioaccumulative and toxic. Application of biosolids to agricultural land may result in soil, groundwater and surface water PFAS contamination via leaching and run-off and pose unknown potential risk to soil health, crops and beneficial biota. This study aims to generate novel knowledge on the PFAS fate in biosolid amended soils, crops and toxicity to key soil and aquatic biota at environmentally relevant concentrations. This study is supported by Australian water and its allied industries, as it is important for them to ensure that biosolids application to agricultural land is an environmentally sustainable solution to the Australian farmers and communities.Read moreRead less
A new management tool for effective wastewater source control. The use of recycled wastewater can dramatically increase the water supply capacity. However, the potential health risk from possible containments in recycled wastewater must be mitigated. This project aims to develop an effective wastewater source management tool for safeguarding the recycled water production and usage.

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

Stormwater is one of the last freshwater resources that has not been utilised to its full potential. However, large amount of faecal pathogens in stormwater limit its harvesting practice.This project aims at addressing this significant problem by developing the next generation of photocatalytic membranes for stormwater disinfection. The proposed membranes not only are passive water treatment technology which only utilises solar energy, but also are operated regardless of weather, even at night. The results will provide new insights on development of future water treatment technologies. This project will also raise Australia’s credibility and competitiveness in the water and membrane industries.Read moreRead less
