Title
Selected Problems in Reverse Osmosis and Nanofiltration
The modern-type composite RO and NF membranes were introduced several decades ago. Despite the wide use in today's desalination and water treatment they still pose many challenging scientific and technological problems. In this talk I describe selected topics studied by my research group over the past several years. They focus on fundamental understanding of the polyamide formation and functioning as a selective medium biofouling and bacterial deposition and membrane modification as a generic way to improve the membrane selectivity and resistance to biofouling.Brief Bio: Prof. Freger holds a faculty position at the Department of Chemical Engineering of Technion -- Israel Institute of Technology in Haifa Israel. He received a M.Sc. degree in chemical engineering from the Mendeleyev Institute of Chemical Technology Moscow and a Ph.D. degree in chemical engineering at the Ben-Gurion University Beer-Sheva Israel. Before joining Technion in 2010 he was a Postdoctoral Fellow at the University of Bath UK and served as a faculty at the Ben-Gurion University and was a visiting scientist at UC Berkeley and Davis. His industrial experience includes collaboration and consultancy for several water- and nano-related companies in Israel USA and Germany. His main expertise is in the areas of membrane technology for water and energy sectors desalination and water treatment. He has extensively published and given invited talks on international meetings on various aspects of membrane transport theory and mechanisms advanced characterization methods use of advanced materials and processes in membrane separations and fouling and biofouling phenomena. He also holds several patents and patent applications in the field.
