Abstract
A method of treating wastewater wherein the biomass associated with the wastewater is subjected to simultaneous nitrification and denitrification in a single reactor. The method entails directing a wastewater influent stream into the reactor and measuring the concentration of N—NHin the influent wastewater stream at a point upstream from the reactor. Air is supplied to the reactor for aerating the biomass in the reactor. The method includes controlling the quantity of air introduced into the reactor based in part at least on the measured concentration of N—NH.
