PROCEDE DE REGULATION DE L'APPORT EN GAZ OXYGENE DANS UN BIOFILTRE A COURANTS ASCENDANTS ET INSTALLATION POUR LA MISE EN OEUVRE D'UN TEL PROCEDE

The conditions in a biological filter for water treatment are monitored and controlled to give optimum removal of carbon and nitrogen. Water for treatment (3) enters the base of the filter (2), collects in the space (7) at the top and is removed (4). Air is injected in two places (5, 5a). The dissol...

description The conditions in a biological filter for water treatment are monitored and controlled to give optimum removal of carbon and nitrogen. Water for treatment (3) enters the base of the filter (2), collects in the space (7) at the top and is removed (4). Air is injected in two places (5, 5a). The dissolved oxygen content and temperature of the treated water in the headspace are measured (10 and 11 respectively), and the amount of oxygen injected adjusted accordingly.
