Workshops

Dr. Wilf frequently conducts training workshops on subjects related water treatment, membrane filtration and reverse osmosis desalination technologies.

Representative outline of training workshop is listed below

Workshops on Membrane Technology, Process and System Design, Operation and Maintenance

Recognized as a global expert for membrane applications, Dr. Wilf shares his expertise with engineering and scientific communities worldwide through technology workshop he is conducting . Dr. Wilf expertise includes reverse osmosis, nanofiltration and membrane filtration technologies applied for seawater and brackish water desalination, potable water treatment, and industrial and advanced municipal wastewater reclamation.

Dr Wilf has been involved in process development, system design, project execution, and plant operation/maintenance of large, commercial desalination plants in the US, Europe, and the Middle East since 1977. Dr Wilf has been involved in development new desalination processes and optimization of membrane technologies. Some of his inventions have resulted in patent applications and are being used in commercial desalination systems.

Dr. Wilf is a regular contributor to professional journals. He wrote chapters on membrane technology processes and applications to a number of books. He co-wrote and edited The Guidebook to Membrane Desalination Technology that was published in 2006. The second book on membrane technology he edited and contributed to, The Guidebook to Membrane Technology for Wastewater Reclamation, was published in January 2010.

The workshops on desalination and advanced wastewater reclamation are conducted worldwide for water treatment professionals: membrane systems design engineers, systems operators and developers of desalination projects.
