(FR) INSTALLATION DE DESSALEMENT ET D'EPURATION DE L'EAU PAR OSMOSE INVERSE ET ULTRAFILTRATION
Abstract
(EN)
In plants for ultrafiltration by reverse osmosis, seals must be provided at the different modular elements (30, 40) between raw water lines and permeate lines. Said seals comprise two sealing rings (100) which are essentially U-profiled, of similar but inverted shape, made of plastic material of which the flexibility is limited, and which are touching pairwise and in tight relationship by one of their branches (140) substantially radially directed in the medial plane of the modular conducting plate (40), their second branch situated outside (130) sealingly striking an adjacent membrane (70), and which present on the outer surface of their bridge portion (120) grooves (111, 112) which conduct the permeate.
(FR)
Dans des installations d'ultrafiltration par osmose inverse, des joints doivent être prévus aux différents éléments modulaires (30, 40) entre les voies de l'eau brute et les voies de conduite de perméat. Les joints comportent deux anneaux d'étanchéité (100), profilés essentiellement en U, de forme semblable mais inversée, à base de plastique dont la flexibilité est limitée, qui se touchent en paire de manière étanche par l'une de leurs branches (140) dirigées essentiellement radialement dans le plan médian de la plaque conductrice modulaire (40), leur seconde branche située à l'extérieur (130) frappant de manière étanche une membrane adjacente (70), et qui présentent sur la surface externe de leur partie de pont (120) des rainures (111, 112) conduisant le perméat.
