Abstract

Installation comprenant une cuve (100) pour séparer les matières en suspension sous forme de boues. La cuve cylindrique (100) munie d un fond (102) forme de bas en haut, une zone de dépôt de boues (Z1) surmontée d une zone de floculation (Z2) elle-même surmontée d une zone de sortie des effluents(Z3, Z4). Le fond (102) a un passage (103) pour les boues. Une entrée d effluents (550) alimente la cuve (100) à travers sa paroi (101) dans la zone de floculation (Z2). Le dispositif d entraînement des effluents (400) dans la cuve(100) comprend des cloisons mobiles (410), montantes, délimitant avec la paroi (101) et le fond (102) de la cuve (100), des compartiments à effluents (CE) ouverts en haut et en bas. Les cloisons (410) laissent libre la partie supérieure (Z4) de la cuve (100) pour former la zone de sortie (104) des effluents nettoyés (SN). Un groupe d entraînement (420) déplace les cloisons (410) à vitesse lente par rapport à la paroi (101) et au fond (102) de la cuve (100).
