Abstract

L'invention concerne un système de raccordement global en chambre compacte de tubes porte-membranes pour le dessalement de l'eau. Ce système comprend un ou plusieurs faisceaux modulaires (15) de tubes porte-membranes (14) empilés et couplés au moyen de fixations (8) respectives. Les raccordements d'acier agissent comme une fixation réelle et chaque tube porte-membranes (14) est pourvu d'un moufle (11) à une extrémité pourvue d'orifices (1, 2, 3, 4) qui unissent les tubes porte-membranes (14) entre eux et les font communiquer avec leurs anneaux respectifs, deux des orifices (1, 4) des tubes extérieurs sont destinés à l'entrée de l'eau salée sous haute pression à travers autant de collecteurs d'eau sous pression (9, 10). Chaque tube porte-membranes (14) est également pourvu d'une paire de sorties (V, 4') de saumure ou d'eau de rejet à son autre extrémité. Ce système comprend également un dispositif de récupération de pression dans un faisceau modulaire (15) de tubes porte-membranes (14) qui traite et met à profit l'excédent d'énergie de la saumure ainsi qu'un collecteur de saumure ou d'eau de rejet qui débouche dans un puits d'évacuation des eaux usées. Chaque tube porte-membrane (14) comprend un tube de récupération de l'eau traitée et dessalée, lequel tube est raccordé à un réservoir de régulation.
