Abstract

L'invention concerne un procédé et un dispositif de clarification par sédimentation. Elle se rapporte à un clarificateur dans lequel le liquide à clarifier parvient par une entrée 15 à une rigole 16 de section uniforme, ayant des trous 25. Un disque ayant une perforation centrale est placé dans chaque trou 25 avec une dimension adaptée afin que les débits dans tous les trous 25 soient égaux. Application à la clarification des eaux usées.
