Overview

Dr Liu Ye is an Associate Professor at The University of Queensland in the School of Chemical Engineering. She was awarded her Ph.D. in 2010 and her research focuses on sustainable and cost-effective water and wastewater treatment, including on-line process control, novel technology development, resource recovery and greenhouse gas (GHG) emissions (monitoring, modeling, and mitigation of N2O) from biological wastewater treatment processes. She has more than 90 publications, including 61 fully refereed journal papers (with over 2000 citation and an h-index of 26 (Scopus, Oct 04, 2019)), and is a co-inventor of four patents. Dr. Ye has been awarded over $3M competitive research funding - including two Discovery Projects, Linkage projects, and the Discovery Early Career Researcher Award (DECRA) Fellowship from Australian Research Council - along with several other industry-funded projects. Liu also received more than eight scientific awards (including Research Innovation Award from Australia Water Association, UQ Foundation Research Excellence Award, etc.), and is an elected management committee member of the (IWA) Specialist Group on Instrumentation, Control, and Automation (ICA). She is also a member of the Australia Association for Engineering Education (AAEE), Engineers Australia (EA) and as a reviewer for 20 international journals. Dr Liu Ye is also affiliated with the Advanced Water Management Centre at UQ.

Research:

Liu’s research includes greenhouse gas (GHG) emissions and mitigation from biological wastewater treatment processes; sludge minimization and biogas production enhancement by using free nitrous acid (FNA) based technology; advanced biological nutrient removal (BNR) technology development; on-line process control and optimisation and resource recovery from wastes.

CHEE4007/4027 Thesis project;

Projects:

  1. Unravelling the dynamics of nitrous oxide production in waterwater systems (ARC Discovery)
  2. Understanding and mitigating nitrous oxide emission from wastewater treatment plants (ARC Linkage)
  3. Bioflim control in wastewater systems using free nitrous acid - a renewable material from wastewater (ARC Discovery)
  4. Quantifying fugitive greenhouse gas emissions from Bolivar WWTP (SA Water)
  5. A novel method for reducing sludge production in wastewater treatment plants (UQ ECR)

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.
