Abstract
L'invention concerne un procédé de traitement des eaux usées qui permet d'obtenir une meilleure réduction de la totalité des solides par respiration endogène, tout en réduisant les demande biochimique d'oxygène et en utilisant la réduction des substances nutritives biologiques. Ce procédé de traitement des eaux usées utilise un système d'aération efficace pour réduire de manière drastique le temps requis pour oxyder la matière organique, remet en circulation, broie et homogénéise la matière organique et les micro-organismes et oxygène la masse entière un nombre de fois beaucoup plus élevé que les systèmes classiques, permettant ainsi d'obtenir un taux de digestion des solides biologiques plus élevé.
