Abstract (en)

[origin: EP0058974A1] In an activation tank (2) containing the waste waters (7) and activated muds, adherence bodies (11) are maintained in balance in a stream (10) of waste waters (7) so that the bodies (11) circulate without creating whirls. The biomass which serves for the nitrification of the waste waters adheres to the bodies (11).
