Aeration strategies to improve nitrogen removal using deammonification process in EGSB reactor.
Anaerobic digestion technology for stabilization and organic matter removal from swine slurry is widely used and long known, but this method not degrades nitrogen compounds present in abundance in the digestate. So, deammonification is being studied as an alternative for post treatment. In this process, two groups of bacteria nitrifying bacteria (aerobic microorganisms) and anammox (anoxic microorganisms) have to cooperate to complete ammonia remove. In this process, the ammonia oxidation by partial nitrification (PN) generate substrate to anammox activity, so there must have PN control to prevent nitrite accumulation. This way making the dissolved oxygen (DO) supply an important key to control and stabilization process. The present study aimed to test the aeration effect on the nitrogen removal using deammonification process in an EGSB reactor. The results show the use of DO control to avoid nitrite accumulation in a deammonification single reactor is a good strategy to increase anammox activity.
