Abstract

L'invention concerne un dispositif de clarification comportant un bac d'activation pour assurer une stabilisation aérobie commune d'eaux d'égout et de boue, avec introduction séparée de l'énergie d'aération et de l'énergie d'entraînement par un tuyau d'air comprimé débouchant dans une buse ou par une hélice. Le dispositif est caractérisé en ce que l'hélice 20 est placée en amont de la buse 21 tandis que le tuyau d'air comprimé débouche dans un dispositif d'aération 23 produisant des bulles fines et placé dans la buse 21. Application aux installations d'épuration d'eaux d'égout.
