Abstract

L'invention concerne un procédé de traitement et/ou de pré-traitement de liquides à filtrer au moyen d'un dispositif à filtre à membrane (102), en particulier de solutions, émulsions ou suspensions aqueuses, caractérisé en ce qu'il comprend les étapes ci-après: les liquides à filtrer sont envoyés dans le dispositif de traitement (100) et/ou le dispositif de pré-traitement (102) et/ou le dispositif de filtration; des champs magnétiques et/ou des champs électromagnétiques (122, 123, 124, 126, 128, 130, 132, 134, 136, 138) sont appliqués dans un dispositif de traitement (300) et/ou un dispositif de pré-traitement (101) et/ou un dispositif de filtration (102), de telle façon que les liquides à filtrer sur membrane (1) soient exposés à ces champs; les liquides traités sont retirés du dispositif de traitement (100), du dispositif de pré-traitement (101) ou du dispositif de filtration.
