Title
(EN) HOLLOW POLYMER FIBERS AS FILTRATION MEMBRANES
(FR) FIBRES POLYMERES CREUSES EN TANT QUE MEMBRANES DE FILTRATION
Abstract
(EN)
The invention relates to a porous hollow fiber comprising a copolymer comprising units derived from vinylidene fluoride and units derived from at least a second comonomer, having a Young's modulus ranging from 2 to 30 MPa and in which the ratio of the mean external diameter thereof to the mean internal diameter thereof ranges from 1.2 to 2. The invention also relates to a filtration module comprising such a hollow fiber, to a process for manufacturing such a hollow fiber, to the use of such a hollow fiber for treating effluent, and also to a process for declogging such a hollow fiber.
(FR)
L'invention concerne une fibre creuse poreuse comprenant un copolymère comprenant des motifs issus du fluorure de vinylidène et des motifs issus d'au moins un deuxième comonomère, ayant un module de Young valant de 2 à 30 MPa et dans laquelle le rapport de son diamètre extérieur moyen par rapport à son diamètre intérieur moyen vaut de 1,2 à 2. L'invention concerne également un module de filtration comprenant une telle fibre creuse, un procédé de fabrication d'une telle fibre creuse, l'utilisation d'une telle fibre creuse pour le traitement des effluents, ainsi qu'un procédé de décolmatage d'une telle fibre creuse
