Abstract

Un dispositif de filtration W1 comprend un tube 42 pour permettre à un liquide 2 dans un réservoir de stockage 1 de s'écouler à l'intérieur et à l'extérieur d'un filtre principal de lavage à contre-courant A, un tube 43 pour amener le liquide 2 à s'écouler à l'intérieur et à l'extérieur d'un filtre secondaire B, et un tube 47 pour amener le liquide de lavage à contre-courant du filtre principal A à s'écouler dans le filtre secondaire B une première vanne 51 pour commander l'entrée et l'arrêt d'entrée du liquide dans le filtre principal A est fournie au tube 42. Une seconde vanne 53 pour commander l'entrée et l'arrêt d'entrée du liquide dans le filtre secondaire B est fournie au tube 43, comme étant une troisième vanne 54 pour commander l'arrêt d'écoulement et de sortie du liquide à partir du filtre secondaire B un tube 63 pour permettre au liquide qui s'est écoulé depuis le filtre secondaire B de s'écouler vers l'extérieur et à s'écouler dans le tube 42 est fourni à un tube 43b1. Une pompe 7 pour aspirer le liquide de lavage à contre-courant dans le filtre principal A et permettre à celle-ci de s'écouler dans le filtre secondaire B est fournie au tube 47.
