6.1.3.5.1.Heterotrophic denitrification

Under oxygen-limited or anoxic conditions, denitrification is usually realized by heterotrophic bacteria in the presence of a suitable electron donor. Electron donors that are often used include

- COD in the influent wastewater

- the COD produced during endogenous decay

- an exogenous source such as acetate, methanol and ethanol.
