Abstract

Procédé pour le traitement d'effluents par oxygénation. Selon le procédé on effectue une dissolution d'air dans un débit de liquide provenant de l'effluent, l'enrichissant en oxygène, et on introduit ce débit liquide enrichi en oxygène dans un bassin contenant l'effluent Le procédé s'applique en particulier à l'épuration des eaux urbaines et industrielles.
