A secondary sewage treatment system is provided with vertically-aligned foam collecting (13), turbulent (12), mixing (11), settling (10), and sludge collecting (9) zones. A grating (7) defines the boundary between the turbulent and mixing zones. Beneath the grating (7), a buoyant media (17), such as hollow plastic spheres, are contained and occupy substantially all of the mixing zone. Air diffusers (18) including elongated draft tubes (8) extend from the turbulent zone (12) down through the mixing zone (11) for introduction of air to aerate waste water liquor and to cause the aerated liquor to recirculate up into the turbulent zone, thereby creating a circulation of waste water liquor from the turbulent zone, down through the mixing zone and around the buoyant media, and up through the draft tubes to the turbulent zone.

Un système de traitement secondaire d'eaux usées, tel que représenté dans la figure 1, est pourvu de zones verticalement alignées de collecte d'écume (13), de turbulence (12), de mélange (11), de dépôt (10) et de récupération de boue (9). Un grillage (7) délimite les zones de turbulence et de mélange. Au-dessous du grillage (7) se trouvent des éléments flottants, tels que des sphères creuses en plastique, lesquelles occupent presque toute la zone de mélange. Des diffuseurs d'air (18), comprenant des aspirateurs-diffuseurs allongés (8), descendent à partir de la zone de turbulence (12) à travers la zone de mélange (11) pour introduire de l'air permettant aux eaux usées d'être aérées et d'être recyclées vers le haut dans la zone de turbulence, ce qui crée une circulation des eaux usées à partir de la zone de turbulence, vers le bas à travers la zone de mélange, autour des éléments flottants, et vers le haut à travers les aspirateurs-diffuseurs jusqu'à la zone de turbulence.
