Abstract

La présente invention concerne une cartouche de purification de l'eau (1) équipée d'un charbon actif extrudé de forme cylindrique (4) formant un espace (5) au sein de la circonférence interne et doté d'ouvertures aux deux extrémités. L'ouverture (5a) située à l'une des extrémités de l'espace (5) est fermée par une section d'étanchéité (6), et l'eau pénétrant dans le charbon activé extrudé (4) est orientée dans l'espace (5) puis libérée par l'ouverture (5b) à l'autre extrémité. La section d'étanchéité (6) est constituée : d'une section d'occlusion (7) qui obture l'ouverture (5a) située à une extrémité ainsi que la surface de la circonférence interne (4b) du charbon actif extrudé de forme cylindrique (4) adjacente à l'ouverture (5a) ; et d'un tamis (8) pourvu d'orifices (8a), qui fait face à la surface d'extrémité (4c) au niveau de l'ouverture (5a) et situé à une certaine distance (E1).
