Abstract

Dispositif de filtration (2) servant à filtrer des milieux liquides pour enlever les solides. Ce dispositif comprend un moyen de filtration (8) fixé à un corps de retenue allongé (9). Ce corps de retenue est inséré à l'intérieur de tubes fendus (6) placés sur la structure de support du dispositif de filtration, ce qui fixe le moyen de filtration à ladite structure de support dudit dispositif. Ceci permet d'introduire facilement le moyen de filtration dans le dispositif de filtration et de le remplacer sans difficultés.
