Abstract: The present invention provides a filtration module comprising a stack of at least two spacers. At least one spacer in the stack comprises a first and a second outer plate and at least one internal permeate channel arranged in between the first and second outer plates such that the outer plates form two of the walls that define at least one internal permeate channel. The at least one internal permeate channel extend between two opposite sides, other than the first and second outer plates, of the spacer. The first and/or second outer plates of at least one spacer are porous or perforated such that liquid may be transported through the pores or perforations to said at least one internal permeate channel. The spacers of the stack are separated by a distance-pieces that are attached to the outer plates along the edge to the opposite sides between which the internal permeate channels extend, thereby forming filtrate channels between adjacent spacers in the stack. The present invention further provides a method for producing a filtration module and a filtration device.

Abstract: Module (10) à membrane enroulée en spirale, présentant une membrane semi-perméable (24), laquelle comporte une région de perméat central (B) à haute pression, bordée sur les côtés opposés par deux parties de bordure (A, C) à pression plus faible. Les parties de bordure (A, C) facilitent la dispersion et la récupération du fluide d'alimentation (93) en cours de traitement, et elles aident à obtenir un écoulement plus uniforme du fluide d'alimentation (93) dans la région à haute pression (B) de la membrane. Dans un mode de réalisation, le module (10) comporte des moyens (20, 20A) d'écoulement d'entrée et de sortie pour un écoulement à contrecourant d'un fluide de balayage dans le perméat. La région de perméat (B) à haute pression est, de préférence, une pièce d'écartement poreuse bordée sur deux côtés de pièces d'écartement poreuses (A, C) de faible densité. Selon un mode de réalisation, la région de perméat (B) à pression plus élevée, ainsi que les régions de perméat (A, C) de bordures à faible chute de pression, sont obtenues par des lignes (301) d'adhésif ou de colle (111), ou lignes positionnées spécifiquement, ayant une taille et un écartement spécifique. Les points (111) (ou lignes) (301) sont positionnés dans une configuration axiale par rapport au conduit central (15). Les points de colle (111) ou lignes (301) sont positionnés dans le passage du perméat (60) dans une configuration permettant d'obtenir un écoulement régulier du fluide de balayage à contre-courant, à courant parallèle, ou à courant transversal.
