Title
(EN) SPIRAL WOUND FILTER ASSEMBLY
(FR) ENSEMBLE FILTRE ENROULÉ EN SPIRALE
Abstract
(EN)
The invention relates to a filter assembly for membrane filtration- of liquids, and more in particular a spiral wound filter assembly with improved filtration performance. Provided is a spiral wound filter assembly comprising a permeate channel (5; 305, 325) for transporting permeate to the permeate outlet (12), said permeate channel being provided with at least one flow restriction (13; 113, 120; 213; 333) in form of check or control valves or ridges, for increasing the pressure in at least part of the permeate channel. The invention further relates to an apparatus comprising such a filter assembly, and to methods for using this apparatus.
(FR)
La présente invention concerne un ensemble filtre pour la filtration de liquides sur membrane, et plus particulièrement, un ensemble filtre enroulé en spirale doté d'une performance de filtration améliorée. L'invention concerne un ensemble filtre enroulé en spirale comprenant un canal pour perméat (5; 305, 325) pour le transport de perméat jusqu'à la sortie (12) du perméat, ledit canal pour perméat étant pourvu d'au moins une restriction d'écoulement (13 ; 113 ; 120 ; 213 ; 333) sous forme de valves ou de cannelures de vérification ou de commande, destinée à augmenter la pression dans au moins une partie du canal pour perméat. L'invention concerne en outre un appareil comprenant un tel ensemble filtre, et des procédés d'utilisation de cet appareil.
