This research report focused on the evaluation of the effects of pH on the inactivation of AOB by chloramines and effects of NOM removal and pH on the rate of ammonia release from the chloramine decay. It was found that water utilities should consider employing pretreatment practices that achieve great stability of chloramine residuals. in order to offset the expenses of periodic strategies to deal with nitrification. Other alternatives to consider for nitrification control are advanced NOM removal strategies or alternative pH values for water entering the distribution system.
