Abstract
Procédé d'élimination de matières en suspension contenues dans des suspensions par filtration à travers des matériaux alvéolaires sans interruption du débit continu des suspensions par une régénération du matériau alvéolaire chargé. On fait affluer dans la zone de filtration la suspension à purifier vers le produit alvéolaire séparant localement, dans la zone de filtration, la suspension d'avec le filtrat, les matières en suspension étant alors retenues sur et dans le produit alvéolaire, le produit alvéolaire entraîné hors de la zone de filtration étant en même temps nettoyé par exprimage du liquide y accumulé, les matières en suspension déposées sur et dans le produit alvéolaire étant ainsi enlevées dans une large mesure et evacuées sous forme concentrée et le produit alvéolaire nettoyé étant à nouveau acheminé dans la zone de filtration.
