The denitrification with the addition of organic matter contributed to the improvement of nitrogen removal efficiency, but a C/N ratio of more than 1.0 severely deteriorated the sludge settleability. The operating factors for the mainstream PN/A determined in the lab scale were applied to the pilot plant. As a result, a nitrogen removal efficiency of 79 ± 11% was stably achieved with effluent total nitrogen of 2.6 ± 1.5 mg/L. However, unpredictable fluctuations in environmental factors revealed that residual ammonium was another criti
