Title
(EN) FORMED SHEET MEMBRANE ELEMENT AND FILTRATION SYSTEM
(FR) ÉLÉMENT DE TYPE MEMBRANE EN FEUILLE FAÇONNÉ ET SYSTÈME DE FILTRATION
Abstract
(EN) A piece of substrate material is formed under heat and pressure against a cavity into a shaped substrate sheet having one or more depressions. Two substrate sheets are bonded together to form a substrate wherein the one or more depressions form one or more interior channels. The substrate, if not formed with pre-coated substrate material, is coated with a dope and quenched to form a filtering membrane. A plurality of membranes may be placed side by side to form a bundle with permeating ends of the membrane, which are open to the one or more interior channels, separated by gaps or spacers. The bundle is connected to a header to produce a module. The module can be assembled into a cassette.
(FR) Selon l'invention, une pièce de matériau substrat est façonnée par application de chaleur et de pression contre une cavité de manière à obtenir un substrat en feuille façonné présentant un ou plusieurs renfoncements. Deux substrats en feuille sont collés l'un à l'autre afin de former un substrat dans lequel le ou les renfoncements définissent un ou plusieurs canaux internes. Le substrat, s'il n'est pas formé avec un matériau substrat pré-enduit, est revêtu d'une solution et trempé pour produire une membrane de filtration. Une pluralité de membranes peuvent être placées côte à côte pour créer un faisceau, les extrémités perméables de la membrane, qui communiquent avec le ou les canaux internes, étant séparées par des espaces ou des entretoises. Le faisceau est relié à un collecteur pour produire un module. Le module peut être intégré dans une cassette.
