Abstract: A process for treating water that includes ammonium. The water is directed to a biological reactor and the quantity of nitrates formed in the reactor and the quantity of ammonium reduced in the reactor is determined. A ratio of the quantity of nitrates formed to the quantity of ammonium reduced is determined. Further, the percentage of ammonium reduced is also determined. The water in the biological reactor is aerated by injecting oxygen into the reactor where the amount of oxygen injected is a function of the ratio and the percentage of ammonium reduced in the reactor.
