A clarifying device for waste water has a plurality of containers for receiving waste water, and a device for aerating or gasifying waste water in at least one of the containers. The containers are formed as treatment cells which are combinable with one another to provide a waste water throughflow and which are small when compared with conventional clarifying reservoirs. The treatment cells are closed from outside. A negative pressure source is connected with the treatment cells for producing negative pressure in the latter.

A clarifying device for waste water comprising a plurality of containers for receiving waste water; means aerating or gasifying waste water in at least one of said containers, said containers being formed as treatment cells which are combined in a series liquid flow arrangement with one another to provide a waste water throughflow, said treatment cells being closed from outside; and negative pressure source means connected with said treatment cells for producing negative pressure in each of the treatment cells, each of said treatment cells being provided with a substantially vertical intermediate wall which subdivides an interior of said treatment cell into two chambers and defines in each treatment cell an upper connecting opening and a lower connecting opening, one of said chambers being provided with a clarifying water inlet and the other of said chambers being provided with a clarifying water outlet, said inlet and outlet being offset relative to one another in a vertical direction, wherein said aerating or gasifying means in said at least one container is located in said other chamber which is provided with said clarifying water outlet so that a transport of waste water from one of said containers to another of said container is caused by airlift of the waste water through air bubbles rising through the waste water in said other chamber of each treatment cell, the bubbles being drawn in by a reduced pressure.
