Research interests

Dr. Messalem specializes in membrane processes for treating municipal and industrial wastewater (particularly in ultra-filtration and micro-filtration, as well as reverse osmosis) and in pre-treating sea-water for desalination.

 

His areas of interest focus on physical chemistry of membranes. Specifically, he deals with membrane and fiber synthesis; characterization of reverse osmosis, ultrafiltration and ion-exchange membranes; fouling mechanisms in membranes; scanning electron microscopy of the morphology of membranes; industrial waste treatment; design and development of waste treatment processes and equipment using cross-flow filtration membranes. Dr. Messalem has also been involved in the Israel Hazardous Waste Survey.

    Professional experien

Senior Research Scientist at the Zuckerberg Institute for Water Research, Ben-Gurion University of the Negev, Israel. Expert in Membrane technologies (Ultrafiltration, Reverse Osmosis, Electrodialysis). Supervising a team of research scientists dedicated to membrane development for desalination, drinking water, municipal and industrial wastewater for the last 30 years.  He spent two years with Prof. K.S.Spiegler at the Seawater Conversion Laboratory in Berkeley, California (1970-1972), and several sabbatical years in industry, among them, head of R&D and Vice-President at Memtek Corp., Boston, a membrane company making commercial membrane systems for industrial wastewater treatment and ultra pure water (1980-1982). He received a Citation Award by the U.S. National Bureau of
Standards for "Contribution to understanding of the properties of membranes" (1972).

He published several papers and patents in the field of water treatment technologies and participated in several EU projects (AVICENNE, AQUAREC and MEDINA, among others).      

Current activities: Desalination and wastewater treatment by membrane processes (Ultrafiltration, Membrane Bio-reactors); Polymeric membrane synthesis; Design and construction of Electrodialysis stacks; Zero Liquid Discharge of Concentrates; Desalination with Solar Energy; Reverse Electrodialysis; Advanced Oxidation Processes (Ozonation of groundwater, solar water detoxification).
