Abstract

L'invention concerne un dispositif transportable destiné à la filtration de l'eau par gravité en vue de produire de l'eau, lequel dispositif comporte un boîtier pourvu d'un ensemble de filtres (G). Selon l'invention, pour créer des conditions de filtration avantageuses, l'ensemble de filtres comporte un ou plusieurs pré-filtres, en particulier un pré-filtre en nylon (3) et un filtre à charbon (4) qui débouche dans une première chambre (6) du boîtier de dispositif (G), laquelle première chambre (6) dispose d'un filtre (7), en particulier en fibres d'ultrafiltration, disposé dans la chambre (6), qui est raccordé par un passage ménagé dans un disque de séparation (10) à un nanofiltre (12) associé à une seconde chambre (13). La seconde chambre (13) est associée à une sortie (14) destinée à l'eau purifiée. Les volumes des première et seconde chambres (6, 13) sont dimensionnés de telle sorte que des impuretés, retenues par l'ensemble de filtres, peuvent être chassées du dispositif par inversion du sens d'écoulement de l'eau à travers l'ensemble de filtres, en particulier par rotation du dispositif de 180° sur un axe horizontal.
