Abstract

L'invention concerne des systèmes de filtration de liquide munis de dispositifs d'introduction de gaz, ainsi que des systèmes et des procédés associés. Dans plusieurs modes de réalisation, par exemple, un système de filtration de liquide comprend une chambre qui possède une entrée et une sortie. Une courroie à filtre est interposée entre l'entrée et la sortie. La courroie à filtre est configurée pour piéger les contaminants tout en permettant au liquide de circuler entre l'entrée et la sortie. Le système comprend en outre un introducteur de gaz configuré pour générer des bulles dans la chambre, près de l'entrée de liquide.
