Abstract

L'invention concerne un élément de collecte d'eau filtrée qui lorsqu'il est lié à une extrémité d'une membrane de filtre de céramique, et lorsqu'une eau filtrée qui a été filtrée avec la membrane de filtre de céramique est envoyée à l'extérieur par l'intermédiaire de l'élément de collecte d'eau filtrée lié à l'extrémité de la membrane de filtre de céramique, il est difficile pour la membrane de filtre de céramique et l'élément de collecte d'eau filtrée d'être liés conjointement de façon sûre à cause des différences de matières des deux. Un module de membrane de filtration de céramique (1) comprend une membrane de filtre de céramique (2) et un élément de collecte d'eau filtrée (25) qui est lié à au moins une extrémité longitudinale de la membrane de filtre de céramique (2) et qui collecte et amène vers l'extérieur l'eau filtrée qui a été filtrée par la membrane de filtre de céramique (2). La membrane de filtre de céramique (2) et l'élément de collecte d'eau filtrée (25) sont liés entièrement par un élément moulé (30).
