La remoción biológica de nitrógeno amoniacal se lleva a cabo en dos etapas sucesivas, la nitrificación y la desnitrificación. La nitrificación se estudió en un grupo de microorganismos aislados a partir de diferentes fuentes acuíferas: una ciénaga eutrificada y aguas residuales procedentes de dos plantas de tratamiento; una de tipo petroquímico y otra de origen doméstico. Los microorganismos se evaluaron en condiciones oxigénicas a 305K en un sistema semicontinuo. Se comprobó la buena adaptación de los microorganismos en aguas residuales de origen petroquímico en procesos de remoción de nitrógeno amoniacal.
Biological removal of ammonia nitrogen is carried out in two successive stages, nitrification and denitrification. This work studied the nitrification process on microorganisms isolated from different aquifer sources: a eutrophicate pond and residual waters from two treatment plants (petrochemical and domestic)
