Filtration dynamique de suspensions de CaCO3 et de solutions de surfactants

Abstract : This thesis focuses on dynamic micro and ultrafiltration conducted on three laboratory pilots, one with rotating membrane disks mounted on two shafts (MSD), one with a disk rotating close to a static organic membrane, and one with a cylinder rotating inside a concentric membrane. The MSD module was first used for ultrafiltration of CaCO3 suspensions, and in these tests ceramic and organic membranes were compared. The results confirmed the importance of disk overlapping in this module. Then, the MSD system was applied to the treatment of model wastewater containing anionic surfactants (SDBS and SDS solutions), and compared with the rotating disk system, which permitted a higher operating pressure. These two dynamic filtration systems present advantages compared to crossflow filtration systems, in terms of the permeate flux and membrane retention. In addition, the rotating disk and the rotating cylinder modules were used for ultrafiltration of bovine serum albumin (BSA) solutions to simulate hemofiltration in the treatment of acute renal failure.
