Abstract

Un module de membrane à fibres creuses avec lequel il est possible d'améliorer la durabilité est divulgué.　Dans le module de membrane à fibres creuses (1), un corps de support (3) comporte des parties de maintien (41, 42), des parties de colonne (51, 52), et des éléments de renfort (6, 7). Les parties de maintien (41, 42) maintiennent respectivement des parties d'extrémité (21A, 21B) d'une membrane à fibres creuses (21), et les parties de colonne (51, 52) supportent les parties de maintien (41, 42) en étant reliées aux parties de maintien (41, 42) de manière respective. Les éléments de renfort (6, 7) sont des éléments pour renforcer les liaisons entre les éléments de maintien (41, 42) et les parties de colonne (51, 52). Chacune des parties de maintien (41, 42) est pourvue d'une partie de liaison (30) formée de telle sorte qu'une partie de colonne (51, 52) peut être reliée respectivement à celle-ci. Les éléments de renfort (6, 7) sont formés de manière à pouvoir être fixés aux parties de liaison (30). Les éléments de renfort (6, 7) présentent des protubérances (63, 73) qui sont des parties qui font saillie vers les parties de liaison (30) ou les parties de colonne (51, 52).
