When the reactor was operated using ammonium and nitrite, then the AOB rich sponge was added, the nitrogen removal rate (NRR) did not increase. On the other hand, when the nitrite concentration was decreased step by step after addition of AOB rich sponge, NRR was reached to 0.5 kgN/m3.day, which was in the range of previous research.
