Question 26 7.5 pts An activated sludge MLE plant is operating at a 16-day sludge residence time (SRT). It is known that the aerobic mass fraction is 50%, DO = 2.0 mg/L in the aerobic zone and Raw TKN = 50 mg/L. Following data are available: Maximum autotroph growth rate uMax = 0.9 / day Observed autotroph decay rate bao = 0.13 / day DO half saturation coefficient k = 0.25 mgO2/L Ammonia nitrogen half saturation coefficient kn = 0.7 mgN/L Determine the effluent ammonia concentration.
