Abstract

L'objet de cette invention est un condensateur électrique à double couche et à écoulement continu, permettant d'éliminer des substances ioniques à une vitesse régulière élevée et se prêtant à une application à échelle industrielle, ainsi qu'un procédé de traitement de fluide au moyen de ce condensateur. L'invention se rapporte à un condensateur électrique plan, à double couche et à écoulement continu, comprenant un séparateur (1) composé d'une feuille poreuse, électriquement isolante et traversée par un écoulement, des couches de charbon actif (2, 2) dont chacune comprend, comme constituant principal, du charbon actif à surface spécifique élevée, des collecteurs (3, 3), placés à l'extérieur des couches (2, 2) de charbon, ainsi que des plaques de retenue (4, 4) disposées à l'extérieur des collecteurs (3, 3). On traite un fluide contenant des substances ioniques en le faisant passer à travers le condensateur et en appliquant de façon répétée, en cycles alternés, une tension continue constante sur les collecteurs (3, 3), et enfin en court-circuitant ou en inversant une connexion entre les collecteurs (3, 3).
