Abstract

L'invention concerne un procédé et une installation de filtrage de liquides. Le procédé est caractérisé en ce qu'on dispose un segment d'agent de filtrage dans une cavité de manière à la diviser en des chambres d'entrée et de sortie qui sont complètement séparées l'une de l'autre par ledit segment, en ce qu'on assure l'étanchéité desdites chambres à l'aide d'un générateur d'énergie hydraulique qui est alimenté en fluide hydraulique à une pression prédéterminée par l'intermédiaire d'une soupape d'arrêt unidirectionnelle empêchant le fluide de sortie du dispositif et en ce qu'on refoule ensuite ledit liquide dans la chambre d'entrée jusqu'à ce que la pression du fluide hydraulique devienne supérieure à ladite valeur prédéterminée. Application aux industries chimiques.
