to improve this situation in our plant, we add the other sludge to this system, and the NH3-N reduction rate will be promoted rapidly(about 7~14 days), but the NH3-N will change to NO2-N,until we add the other sludge to this system the same ,but we lower the DO, and the NH3-N change to NO3-N. now we will look on the NH3-N reduction rate will be stable,in the lack of NO2-N in our aerotion tank.
