Dual-membrane upgrading towards sustainable wastewater management. Water utilities in Australia have set aspirational targets for energy- and carbon-neutral wastewater services by as early as 2030. However, these two aims are often incompatible because of excessive aeration energy consumption and substantial greenhouse gas emissions in wastewater treatment plants. This project aims to develop a novel biotechnology that enables simultaneous bioenergy recovery, cost-efficient nitrogen removal and ....Dual-membrane upgrading towards sustainable wastewater management. Water utilities in Australia have set aspirational targets for energy- and carbon-neutral wastewater services by as early as 2030. However, these two aims are often incompatible because of excessive aeration energy consumption and substantial greenhouse gas emissions in wastewater treatment plants. This project aims to develop a novel biotechnology that enables simultaneous bioenergy recovery, cost-efficient nitrogen removal and mitigation of greenhouse gas emissions, thus bringing multifaceted benefits to wastewater management. The project will provide strong support to the Australian water industry in their endeavour to achieve economically and environmentally sustainable wastewater services.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
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
