This breakdown of nitrate from the waste stream releases oxygen and nitrogen gas. Anoxic Tank. In order for denitrification to occur, anoxic conditions must exist. Anoxic conditions are deficient in dissolved molecular oxygen but it can contain chemically-bound oxygen as found in nitrate The simple distinction between anaerobic and anoxic conditions in wastewater practice is that anearobic condition means there is no molecular oxygen and no oxidized nitrogen species (i.e, nitrite, 2021-04-01 2014-03-19 If this conversion is completed in the middle of the tank this will give you 1/3 of the tank to establish an anoxic zone. An anoxic zone will enable you to not only convert the nitrogen but to remove it.
