讲座内容：The supply of water is a matter of life and death for the human society. With increasing world population (7 Billion last year and projected to increase to 9.5 billion in 2050), urbanization and climate change, the need for further water resources is critical. Globally, sea water desalination with Reverse Osmosis (SWRO) is an increasingly popular option implemented to augment the water supply for many coastal cities (e.g. Singapore, Sydney, etc). Significant advancements have occurred in recent years in membrane technology, process control and brine management, and together they have led to a considerable reduction in the water production cost. At the same time, the output capacity of SWRO plants is increasing rapidly to achieve an economy of scale, and the brine flow rate to the sea has also increased correspondingly.
SWRO involves many major processes that have close relevance to environmental hydraulics, which can be broadly defined as the consideration of water quality in fluid flows. These processes include the design of intakes, pretreatment, RO, energy recovery, and brine disposal. All of them require a good understanding of the physical processes based on environmental hydraulic principles. In this seminar, some areas of research related to SWRO being undertaken in the research group of the author will be presented.
报告人简介：A/P Adrian Law Wing Keung received his PhD from the University of California at Berkeley. He was a practicing engineer in the USA for more than 7 years, before joining the academic faculty of the School of Civil and Environmental Engineering, Nanyang Technological University (NTU), Singapore. His current research focuses on using the knowledge of environmental fluid mechanics to improve the design of membrane and desalination systems. He was recognized with the Wesley Horner Award by the American Society of Civil Engineers (ASCE), and two Outstanding Technical Paper Awards by the Bechtel Corporation, USA. He was also UPS Foundation Visiting Professor at Stanford University, William Mong Research Fellow at the University of Hong Kong, and also Faculty Fellow of the Singapore-MIT Alliance for Research and Technology. Currently, he is the Executive Committee Member of the International Association of Hydro-environment Engineering and Research (IAHR) Asian Pacific Division, Vice-Chair of the Joint IAHR-IWA Committee on Marine Outfall Systems, as well as in the Editorial Board of a few related journals in this area. In Singapore, he is also the co-Director of the DHI-NTU Water and Environment Research Centre and an active research member in the Singapore Membrane Technology Centre.
