Abstract
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.
