Inhibition effect of free ammonia on deammonification process under different intermittent aeration strategies in sequencing batch reactor
PublicationThe deammonification process involves two steps. The first step is the partial nitrification of ammonia (NH4-N) by ammonia oxidizing bacteria (AOB) to produce nitrite (NO2-N) and the second step is the anammox process to “anaerobically” oxidize ammonia to nitrogen gas with nitrite as an electron acceptor (Lackner et al., 2014). Free ammonia (FA) plays a significant role in the stable, long-term deammonification system operation....
