Abstract

Procédé consistant à faire monter le liquide devant être clarifié et subdivisé en courants parallèles partiels dans des canaux inclinés sur l'horizontale et dans lesquels les particules se déposent, glissent vers le bas à contre-courant par rapport au liquide, puis en sortent, traversent le liquide et tombent sous la zone d'arrivée dans une zone d'épaississement du sédiment. Un second clarificateur 24, à canaux inclinés sur l'horizontale et dans lesquels descend le sédiment, est disposé sous la zone 20 d'entrée du. liquide devant être clarifié, le sédiment devant passer dans ce clarificateur avant d'atteindre la chambre 25 collectrice des particules déposées. Application à l'épuration des eaux usées.
