A 20Year Journey of Partial Nitritation and Anammox (PN/A):
Anaerobic ammonium oxidation (anammox) was discovered as a new microbial reaction in the late 1990s, which led to the development of an innovative energy and carbonefficient technology─partial nitritation and anammox (PN/A)─for nitrogen removal PN/A was first applied to remove the nitrogen from highstrength
