Abstract

Le secteur technique de ce second certificat d'addition est celui de la filtration. L'invention se rapporte à un dispositif de filtration selon l'une quelconque des revendications du premier certificat d'addition, caractérisé par le fait que chaque alvéole est pourvu d'un fond cannelé de collecte du liquide de filtration, traversant une toile correspondante, et que la surface correspondante de tambour est elle-même pourvue de cannelures, recouvertes d'une seconde toile entraînée par ledit tambour et traversée par les arrivées de la boue à filtrer. Application à l'amélioration du rendement de la filtration et à la simplification de la construction.
