Abstract

Un bioréacteur à membrane immergé dans un seul réservoir destiné au traitement d'une eau d'alimentation présentant des niveaux inacceptables d'ammoniaque ou d'azote total présente à la fois une alimentation en bulles de lavage à membrane et une alimentation en bulles d'oxygénation. L'alimentation en bulles de lavage à membrane produit en continu de grosses bulles de lavage afin de nettoyer les membranes. Le perméat est retiré de façon continue des membranes à haut débit mais les grosses bulles de lavage ne transfèrent pas suffisamment d'oxygène dans la liqueur mélangée pour créer des conditions aérobies dans le réacteur. L'alimentation en bulles d'oxygénation est exploitée pour produire des petites bulles d'air ou d'oxygène produisant, de façon intermittente, des conditions aérobies dans une partie significative de la liqueur mélangée. Des conditions aérobies et anoxiques alternées se produisent dans une partie importante du réservoir apte à la nitrification et la dénitrification. Le niveau d'oxygène dissous (OD) ou de potentiel de réduction d'oxygène (PRO) dans le réservoir est mesuré par des détecteurs et il détermine quand l'alimentation en bulles d'oxygénation doit être mise en marche ou coupée entre des limites définies de temps minimum et maximum.
