Research impacts
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, with solid and active collaboration with Australia water utilities. Research outcome has set a benchmark for reducing emissions by 35% at one of the largest Australian treatment plants in Adelaide, translating to potential annual savings of $50M for the water industry.
- GHG outcome featured as an exemplar of how chemical engineering can drive real change for a better future, as recognized by the IChemE in their publication "Chemical Engineering Impact in Australia" at the end of 2019.
- Featured by IChemE Sustainability Hub: Sustainability success stories on “Wastewater treatment and process emissions – Dr Liu Ye”, (https://www.icheme.org/knowledge-networks/sustainability-hub/sdg-6-clean-water-and-sanitation/making-a-difference-sustainability-success-stories/)
- Her methodology for real-time greenhouse gas emission measurement, which was applied in Melbourne Water’s full-scale treatment plant, won the 2022 Australia Water Association Research Excellence and Innovation award (Victoria region).
- 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.
