Zone of aeration definition.

Anoxic conditions involve environments in which molecular or free oxygen (O 2) is absent, though bound oxygen may be present. “Anoxic” refers to the state of the environment rather than microorganisms and their processes. In wastewater treatment, anoxic conditions differ from anaerobic conditions based on the presence or absence of nitrogen.
