Title (EN) CONTROL OF BACTERIAL ACTIVITY, SUCH AS IN SEWERS AND WASTEWATER TREATMENT SYSTEMS
(FR) CONTRÔLE DE L'ACTIVITÉ BACTÉRIENNE DANS LES ÉGOUTS ET LES SYSTÈMES DE TRAITEMENT DES EAUX USÉES
Abstract: front page image
(EN)A method for controlling the activity of sulfate reducing bacteria or methanogenic archaea (or both) in environments containing such organisms comprising treating the environment with free nitrous acid (HNO2) or with a solution containing nitrite (NO2-) having a pH of less than 7 or by adding nitrite to the environment and having a pH of less than 7 in the environment. The method can also disrupt biofilms.
(FR)Cette invention concerne un procédé de contrôle de l'activité des bactéries réductrices de sulfates et/ou les archées méthanogènes dans des environnements contenant ces organismes, ledit procédé consistant à traiter l'environnement avec de l'acide nitreux libre (HNO2) ou avec une solution contenant des nitrites (NO2-) ayant un pH inférieur à 7, ou en ajoutant des nitrites ayant un pH inférieur à 7 dans l'environnement. Le procédé selon l'invention permet également de disjoindre des biofilms.
