“Moreover, the addition of Fe(III) could stimulate N2O emission transitorily during SNDPR process.”
“The TN removal was weakened when Fe(III) load reached to 60 mg/L, and the N2O yield was lower than control, due to the inhibition of the high Fe load on denitrification enzymes.”
“When Fe(III) load was 40 mg/L in the reactor, the N2O yield was 10 % higher than control.”
