Title (EN) METHOD FOR STABILIZATION OF BIOLOGICAL CULTURES TO ALLOW BIOLOGICAL TREATMENT OF BRINES
(FR) PROCEDE DE STABILISATION DE CULTURES BIOLOGIQUES POUR PERMETTRE LE TRAITEMENT BIOLOGIQUE DE SAUMURES
Abstract: front page image
(EN)A process is disclosed for the biological treatment under anaerobic/anoxic conditions for the degradation of pollutants present in brine solution used in waste water management, in industrial waste brine solutions and in waste oil field brine solutions, especially waste brine solutions contaminated with perchlorate and nitrate. A culture capable of reducing perchlorate and nitrate in spent ion-exchange regenerant brine containing at least 30 g/L NaCl under anaerobic/anoxic conditions was used to demonstrate the process. A stabilized brine solution is also disclosed in which a culture capable of degrading a given pollutant can be proliferate.
(FR)L'invention concerne un processus de traitement biologique en conditions anaérobies/anoxiques pour la dégradation de polluants présents dans une solution de saumure utilisée dans la gestion des eaux usées, dans des solutions de saumure usée industrielle et dans des solutions de saumure usée de champ pétrolifère, en particulier dans des solutions de saumure usée contaminées au perchlorate et au nitrate. Une culture capable de réduire la teneur en perchlorate et en nitrate dans une saumure usée de régénération d'échange d'ions contenant au moins 30 g/L de NaCl en conditions anaérobies/anoxiques a été utilisée pour démontrer ce processus. Cette invention concerne également une solution de saumure stabilisée, dans laquelle une culture capable de dégrader un polluant spécifique peut proliférer.
