Abstract

L'invention porte sur une enveloppe pour un module membranaire à fibres creuses (1) dotée d'un trou traversant (2) servant de canal d'écoulement de fluide dans une surface de paroi, l'enveloppe pour un module membranaire à fibres creuses ayant des nervures arrondies (4, 4', 4'', …) disposées agencées sur une partie de bord à angle aigu du trou traversant sur le côté interne de l'enveloppe et étant en outre de préférence dotée d'un treillis dans le trou traversant sur le côté interne de l'enveloppe. Cette enveloppe pour un module membranaire à fibres creuses permet de réduire l'endommagement lorsqu'un module membranaire à fibres creuses logé dans celle-ciladite enveloppe est utilisé par comparaison avec une enveloppe classique pour une membrane en fibres creuses dotée d'un trou traversant servant de canal d'écoulement de fluide dans une surface de paroi.
