Abstract

Installation comprenant une zone d'aération et au moins une zone de clarification séparées par une paroi verticale laissant passer la suspension pour son recyclage. Le bassin comprend une paroi inclinée 12 définissant avec la paroi verticale 14 une zone intermédiaire de filtration-floculation. En dessous de cette zone se trouve une zone de concentration des boues. La paroi inclinée 12 et le fond incliné 10 du bassin ont approximativement la même pente d'environ 60 degrés et la même hauteur. L'installation est destinée à l'épuration des eaux.Installation comprising an aeration zone and at least one clarification zone separated by a vertical wall allowing the suspension to pass through for recycling. The basin comprises an inclined wall 12 defining with the vertical wall 14 an intermediate filtration-flocculation zone. Below this area is a sludge concentration area. The inclined wall 12 and the inclined bottom 10 of the basin have approximately the same slope of about 60 degrees and the same height. The installation is intended for water purification.
