Abstract:
Water shortage is a global consensus, and advanced water treatment technologies are receiving increasing attention. Among those technologies, catalytic ozonation has obtained widespread interest from researchers due to its good performance and short treatment time, and is gradually becoming popular in engineering applications. However, catalytic ozonation faces problems such as unstable long-term performances, unknown ecological toxicity, unclear disinfection and sterilization efficiencies in water and secondary pollution caused by the dissolution of active metals. These problems restrict the expansion and promotion of this technology in the field of water treatment. Further in-depth research is needed to solve those scientific and technical problems. Dr Pan prepared 2 kinds of catalysts (one for wastewater treatment and the other for drinking water purification) to address those issues. His research results reveal the mechanisms of ozonation catalysis and the pathways of pollutants’ degradation via lab-scale study, and the application performance and operating cost of this technology were also analyzed based on the engineering applications. This study expands the application fields of catalytic ozonation technology from advanced wastewater treatment to advanced drinking water purification, providing theoretical and technical support for novel advanced water treatment.

Bio:
Dr. Jian PAN is a senior engineer in China and consultant expert for Beijing and Zhejiang government entities, also a member of the International Water Association-Young Water Professionals China Chapter. He got his bachelor’s and PhD degrees from Zhejiang University and master’s degree from King Abdullah University of Science and Technology (his advisor was Prof Gary Amy of Water Desalination Reuse Center). He has applied 10 patents for invention, published 14 research papers and accomplished 6 national or provincial funded research projects and 2 municipal funded research projects. For the past 10 years, he was mainly engaged in catalyst industrialization and businesses incubation. In particular, he has got rich experiences in the research and development, production and application of environmental protection catalysts. Those catalysts have been applied to nearly 30 projects, whose treatment capacities range from tens of t/d to 10,000 t/d or more. He received the KAUST Alumni Change Makers Award in 2022 as well as the first prize of Water Conservancy Science and Technology Innovation Award of Zhejiang Province in 2023. He is also the president of KAUST China Alumni Chapter.
