Abstract

La présente invention concerne un procédé et un appareil de filtration continue d'une masse imprégnée de liquide. Ce procédé est caractérisé en ce qu'on exerce d'une manière discontinue la pression sur des portions successives de la masse à filtrer défilant en continu de façon que cette pression reste appliquée à chaque portion de la masse pendant son déplacement sur une distance prédéterminée, après quoi on cesse d'appliquer la pression à cette portion pour l'exercer sur la portion suivante de la masse. Applicable à la filtration de boues.
