What was dissolved oxygen levels, there did not seem to be any ammonia nitrification? Also alkalinity and pH were low on occasion, these will be key to sustain nitrification, something is happening but not consistent? Something else inhibiting nitrifiers?

1.The DO is about 4 ppm.
2.The TKN of inflow is 30~40 ppm, the TKN of effluent is 4 ppm, the NH3-N is nitrification.
3.The pH is about 7, and the cresol (about 30 ppm) maybe the inhibitor, but we still need to check.
