Abstract
L'invention concerne un procédé de dénitrification d'une solution comprenant l'introduction dans la solution d'une quantité d'une source de carbone pendant une durée et à une fréquence telles que les bactéries indigènes hétérotrophes consomment l'oxygène dissous dans la solution et décomposent l'oxygène du nitrate de la solution pour obtenir l'oxygène lui étant associé. L'invention concerne également des appareils et composés associés.
