Fill-and-draw completely mixed activated sludge reactors were used to determine the effects of MLVSS concentration, pH, and temperature on nitrification rate. Forty-five experiments were divided into three series of MLVSS concentrations. Each series of 15 experiments were distributed among three different pH groups. In each group, five experiments were conducted at 4°, 10°, 17°, 25°, and 33°C. The best nitrification performance was obtained at pH 8.3, between 25° and 33°C. There was no interaction between the effects of temperature and pH. However, a change in biomass concentration altered both the pH and temperature dependence of the process. The temperature coefficient is expressed as a function of MLVSS concentration.
