The effect of pH on NO production in intermittently-fed nitritation reactors.

The effect of pH on nitrous oxide (NO) production rates was quantified in an intermittently-fed lab-scale sequencing batch reactor performing high-rate nitritation. NO and other nitrogen (N) species (e.g.

The pH dependency of N-converting enzymatic processes, pathways and microbes: effect on net N O production.

Nitrous oxide (N O) is emitted during microbiological nitrogen (N) conversion processes, when N O production exceeds N O consumption. The magnitude of N O production vs. consumption varies with pH and controlling net N O production might be feasible by choice of system pH.
