The invention relates to a membrane filter system which comprises at least one container in which a plurality of ventilated parallel cross-flow filter modules (7) is disposed which can be removed from the membrane filter system individually, and wherein every filter module comprises a plurality of membrane units of the same kind. The invention is characterized in that the container is subdivided into a plurality of compartments by walls that are disposed perpendicularly to the cross-flow direction of the filter modules (7). At least one compartment (3; 9; 13; 14) of the plurality of filter modules (7) serves for the common supply of the suspension to be filtered, the common discharge of the retentate or the common discharge of the permeate. The invention allows for a denser arrangement of filter modules (7) as it eliminates the need for tubing the individual filter modules for removing the permeate and/or the retentate and/or for supplying the suspension to be filtered (feed).
L'invention concerne un dispositif de filtre à membrane composé d'au moins un contenant comportant plusieurs modules de filtre ventilés (7), pouvant être parcourus parallèlement et extraits individuellement du dispositif de filtre à membrane, un module de filtre comportant plusieurs unités de membrane identiques. Selon l'invention, le contenant est divisé en plusieurs espaces par l'intermédiaire de fonds disposés perpendiculairement au sens d'écoulement des modules de filtre (7), au moins un espace (3; 9; 13; 14) de la pluralité de modules de filtre (7) étant destiné à l'acheminement commun de suspension à filtrer, à l'évacuation commune de rétentat ou à l'évacuation commune de perméat. Ainsi, il est possible d'augmenter la densité de disposition des modules de filtre (7) du fait qu'on s'affranchit de la tubulure des modules de filtre individuels servant à l'extraction de perméat et/ou de rétentat et/ou à l'acheminement de suspension à filtrer.
