Abstract

L'invention se rapporte à un filtre modulaire conçu pour des matières liquides et particulaires gazeuses. Ce filtre comprend au moins deux modules en céramique ou céramique poreuse. L'invention se rapporte également à un filtre comprenant un élément de filtration, et un élément servant à régénérer l'élément de filtration, cet élément de régénération faisant partie intégrante de l'élément de filtration. L'invention se rapporte en outre à un procédé permettant de recouvrir des articles d'une couche conductrice. Des dispositifs pouvant être utilisés conjointement avec à la fois des filtres modulaires et/ou régénératifs sont également décrits.
