The invention relates to an improved separation device in which a plate unit containing the filter comprises a separate abutment ring (20) and a cassette (30) which can be easily connected thereto, said cassette comprising at least one filter (15) together with, if required, a frame belonging thereto so as to support the filter. If the filter consists of a flexible membrane, this is fitted into a special frame. However, if the filter is a rigid, self-supporting filter of a porous material, for example, a ceramic filter or the like, a separate frame is not needed to support the filter. The separation device according to the present invention does not require a separate outer cover.
L'invention se rapporte à un dispositif de séparation amélioré dans lequel une plaque contenant le filtre comprend un anneau d'appui séparé (20) auquel peut être facilement raccordé une cassette (30) qui comporte au moins un filtre (15) ainsi que, si nécessaire, un cadre faisant partie de cette cassette, de manière à supporter le filtre. Si le filtre est constitué d'une membrane flexible, celui-ci s'adapte dans un cadre spécial. Toutefois, si le filtre est un filtre rigide autoporteur en matière poreuse, tel qu'un filtre céramique ou autre, un cadre séparé n'est pas nécessaire pour porter le filtre. Ce dispositif de séparation ne nécessite pas de couvercle externe séparé.
