Abstract:
1. A process for liquor—particularly wastewater—agitation and/or aeration having the following cyclically repeated steps a) and b): a) aerating the liquor by means of an immersed aerator for a predetermined first period of time using a diffuser disposed on a carrier designed as a floodable hollow body, the hollow body being flooded and air being brought into the liquor by the diffuser, making it possible to create nitrification in the liquor; b) agitating the liquor by means of the immersed aerator for a predetermined second period of time, the air feed by the diffuser being throttled or turned off, and the previously flooded hollow body being evacuated in order to fill the hollow body with gas or air, the immersed aerator assuming the function of an agitator by rising upward in the liquor, thus agitating the liquor, making denitrification possible in the liquor.
