|a This study successfully revealed the importance of probe reliability and sensitivity with ion sensitive electrode (ISE) probes on achieving high partial denitrification (PdN) efficiency; and decreasing carbon overdosing events that cause the decline of microbial populations and performance of PdNA. In a mainstream integrated hybrid granule-floc system, an average PdN efficiency of 76% was achieved with acetate as the carbon source. Thauera was identified as the dominant PdN species; its presence in the system was analogous to instrumentation reliability and PdN selection and was not a consequence of bioaugmentation. Up to 27-121 mg total inorganic nitrogen/L/d, an equivalent of 18-48% of the overall total inorganic nitrogen removed, was achieved through the PdNA pathway. Candidatus Brocadia was the main anoxic ammonium oxidizing bacteria species that was seeded from sidestream and enriched and retained in the mainstream system with observed growth rates of 0.04-0.13 day-1 . Moreover, there was no direct negative impact of methanol's use for post-polishing on anoxic ammonium oxidizing bacteria activity and growth. PRACTITIONER POINTS: Stress testing with ISE sensors revealed the importance of probe reliability and sensitivity on PdN selection and PdNA performance. Up to 121 mg TIN/L/d was achieved via PdNA in a mainstream suspended hybrid granule-floc partial denitrification-anammox (PdNA) system. Candidatus Brocadia was the dominant AnAOB species with observed growth rates of 0.04-0.13 day-1. There was no direct negative impact of methanol's use for post-polishing on AnAOB activity and growth
