Great to see my first first-author as a Process Engineering Associate at Black & Veatch! Here we used biomass from anaerobic digester and evaluated mechanisms of nitrogen removal in a process called “post aerobic digestion”. We found that, while NOB are present, AOB are responsible for nitrite accumulation that then it’s further reduced via denitritation. This suggests that nitritation-denitritation (shortcut nitrogen removal) is the dominant mechanism of nitrogen removal in post aerobic digestion reactors.
