Title (EN) HOLLOW-FIBER MEMBRANE AND PROCESS FOR PRODUCTION OF HOLLOW-FIBER MEMBRANE
(FR) MEMBRANE FIBRE CREUSE ET PROCÉDÉ DE FABRICATION D’UNE MEMBRANE FIBRE CREUSE
(JA) 中空糸膜及び中空糸膜の製造方法
Abstract: front page image
(EN)A module provided with a hollow-fiber membrane which has a dense layer either on the inside or on the outside and in which the aspect ratios of pores formed on the dense-layer-side surface of the membrane are 3 to 5.  The module exerts purification performance higher than that expected to be attained by an increase in membrane area and can reduce the frequency of cartridge replacement.
(FR)L’invention concerne un module muni d’une membrane fibre creuse qui possède une couche dense à l’intérieur ou à l’extérieur et pour laquelle les rapports longueur/diamètre des pores formés sur la surface du côté à couche dense de la membrane sont de 3 à 5. Le module exerce une performance de purification supérieure à celle prévue par une augmentation de l’aire de la membrane et peut réduire la fréquence de remplacement de la cartouche.
(JA)内側および外側のうちの一方に緻密層を有し、かつ緻密層を有する側の膜表面に形成される孔のアスペクト比が3以上5以下である中空糸膜を備えたモジュールを有することにより、膜面積増大分以上に除濁性能を向上させることができ、カートリッジとして、交換頻度が少なくすることができる。
