Raja Ben Amar

CV
Raja Ben Amar currently works as a professor in the Chemistry Department at the Faculty of Science in Sfax, Tunisia, and heads the “Membrane Technology, Water and the Environment” group. She obtained her master's degree in chemical engineering from the Institut Polytechnique de Lorraine (France) and her doctorate in chemical engineering from the Institut Polytechnique de Toulouse (France). Her main research interests are wastewater treatment using hybrid processes, water desalination and the development of new porous ceramic membranes based on natural and hybrid materials. She has published over 230 articles, including 100 in ISI-indexed journals. She is a reviewer for several scientific journals.  She is currently vice-president of the African Membrane Society.


Program
I. Membrane from material to process

  • Membrane preparation and fabrication methods
  • Membrane structure and characterization techniques (porosity, pore size, filtration layer, surface functionality)
  • Membrane transfer mechanism (according to the membrane structure and pore size)

II.  Membrane processes and limitation in terms of permeate flux and solutes-membrane interactions:

Influence of the pore size and membrane structure (symmetric and asymmetric) and chemical composition (hydrophobic-hydrophilic, mineral-polymeric)

III. Membrane structure - Applications relationship :

  • hydrophilic = aqueous filtration with pore size depending on the application (MF, UF, NF, RO)
  • oil/water separation = hydrophobic
  • food processing applications = ceramic membranes (sterilization, cleaning, ...)
  • gaz filtration  = hydrophobic (MF or UF for water solution degassing, membrane distillation) dense membrane for gaz separation

IV. New trends:

  • Low-cost membrane fabrication and potential applications
  • Membrane treatment for circular economic approach with a case study
