Résumé
This thesis has focused on the definition of a simulation tool for clarification operation by porous membranes to identify the dominant mechanisms membrane fouling during operations defined quantify the dynamics of clogging and optimize working conditions (filtration conditions and regeneration conditions in line).The work is particularly interested in BioReactor Anaerobic Membrane (BRMAn) is a technology that has been proven in the treatment of municipal and industrial water. It combines (i) biological treatment anaerobic allowing almost complete treatment of organic pollutants with a production of a source of energy (methane) and (ii) the membrane treatment ensuring total separation of the solid phase (biomass) and the liquid phase (water treated), for obtaining a high purity water.
