NITRIFICATION PRESERVATION IN ACTIVATED SLUDGE DURING CURATIVE BULKING CHLORINATION

Nitrifying activity preservation in activated sludge during curative bulking chloration. The present study deals with the impact of the injection of sodium hypochlorite, used to control the bulking, on the nitrifying flora. The preservatives effect on nitrification of the lowest concentration of chlorine at the dosing point and therefore of the highest pass frequency was demonstrated.
