“…The latter explanation correlated well with the observations that PdN performance was dependent on nitrate concentration, thus potentially indicating that electron transport from cytochrome b to cytochrome c only occurred after electron demand from cytochrome b decreased. This study therefore suggests that COD/NO3--N is not the direct control mechanism unlike other studies suggested (Du et al, ; Ma et al, ; Sharp et al, ), rather operation under a minimum nitrate concentration was. Similar nitrate and nitrite profiles were established under limiting (COD/NO3--N of 3) and nonlimiting carbon dosing (COD/NO3--N of 10; Figure a,b) confirming this hypothesis.…”

“…In a case study by Gong et al (), nitrogen profile under acetate feast‐famine condition with different COD/NO3--N ratio varied from 1.4 to 3.5 and initial nitrate concentration varied from 16.8 to 79.3 mg NO3--N/L, all the results shared the similar observation that nitrite accumulated when nitrate was above 2 mg N/L. Nitrate residual concentration as key factor to control the switch from PdN to FdN can also be extracted from studies combining PdN and AnAOB in suspended sludge (Du et al, ) and biofilms (Ma et al, ). Nonetheless, all of the above studies shared the same COD dosing approach which was based on low COD/NO3--N (2–3) to control PdN and had nitrate levels in the effluent of 2–3 mg N/L (Du et al, ; Gong et al, ; Ma et al, ).…”
