Anaerobic ammonia oxidation (Anammox) process is a novel biological
nitrogen removal technology. Nitrite is
an electron acceptor and ammonium is oxidized to nitrogen gas through Anammox biochemical reaction. The doubling time of Anammox bacteria is about 7-10 days, thus
seeding source, reactor design and operation conditions are important factors
for applying Anammox process for nitrogen removal.
NH4++ 1.32 NO2-+ 0.066 HCO3- + 0.13 H+ → 1.02 N2+ 0.26 NO3-+ 0.066 CH2O0.5N0.15 + 2.03 H2O
According to the reaction, oxygen consumption of Anammox process is about 1/3 of A/O process, it is an energy saving nitrogen removal process.
