Abstract
La présente invention concerne un appareil (1) à fixer à une unité (2) de filtre, afin de générer une impulsion arrière d'un écoulement à travers une membrane de filtre de l'unité (2) de filtre. L'appareil (1) a le moyen d'entraîner un écoulement dans une première direction, à une première vitesse et dans une seconde direction, à une seconde vitesse. La seconde vitesse n'est pas la même que la première.
