Patent

CA 2169163

There are described a method of and an apparatus for removing sand from waste water loaded with sand and organic substances which is set forth in circulation in a vertical container (1) in which the organic substance moves upward to an overflow (13), while the sand sinks downward toward a discharge conveyor (3) connected to the container (1) from beneath, and is discharged after a certain settling period. To achieve a substantial separation of the sand and the organic substances, the settled sand is stirred by an agitator, with simultaneous rinsing with fresh water delivered to the container bottom region, and is discharged in an amount, which insures a predetermined minimal height of the settled sand.

L'invention concerne un procédé et un dispositif permettant d'extraire du sable contenu dans des eaux usées chargées en sable et en substances organiques, qui sont brassées dans un réservoir (1) vertical. Les substances organiques sont ainsi déplacées vers le haut en direction d'un trop-plein (13), tandis que le sable descend vers le bas en direction d'un convoyeur de rejets (3) raccordé en bas du réservoir (1) et n'est déchargé qu'après un temps de dépôt. Afin de parvenir à une séparation conséquente du sable et des substances organiques, le sable déposé est remué par un agitateur (4) avec rinçage simultané avec de l'eau acheminée dans la zone du fond du réservoir (1) et n'est déchargé qu'en une quantité permettant d'assurer une hauteur minimale prédéfinie de sable (18) déposé.
