Abstract

L'invention concerne une installation de traitement des eaux usées avant leur entrée dans le dispositif de clarification. Cette installation comporte un réservoir 2 divisé par une grille à fentes 4 en des compartiments d'arrivée et de départ dans lesquels règne la même pression hydrostatique, un courant d'eau continu étant prévu entre l'orifice d'arrivée 1 et le collecteur de départ 9, les matières grossières et les matières fibreuses, ainsi que d'autres matieres organiques non encore séparées étant retenues par la grille. L'invention est applicable au traitement des eaux résiduaires.
