Research Impacts
A/Prof Liu Ye's research is having a substantive impact in gaining a deeper scientific understanding of biological nutrient removal and recovery during wastewater treatment and outputs from her research are used by industry to recover nutrients from wastewater and reduce greenhouse gas emission and activate sludge production during wastewater treatment, which directly benefits the Australia water utilities and the living environment-:
- Leader and one of the key drivers to the development of N2O research at UQ AWMC. As the project manager and co-leader of the N2O research group at AWMC, Liu works closely with Australia water utilities and have built strong collaborations with several industry partners (Western Australia Water Corporation, Melbourne Water Corporation, and South Australian Water Corporation).
- Developed the first systematic approach to quantify the N2O emissions from wastewater system with surface aerators. It was successfully applied to estimate the N2O emission factor for a well-mixed full-scale oxidation ditch wastewater treatment plant in Perth.
- Her ground-breaking research has led to substantial development and commercialisation of the free nitrous acid (FNA) technology. Her research revealed, for the first time, FNA at a low concentration can completely suppress bacterial growth. This research, together with another research result, underpinned the application of FNA as a green chemical to control biofilm growth on sewers and to reduce the sludge production during urban wastewater treatment.
