Abstract

La présente invention concerne un procédé de réduction du carbone organique total d'un flux d'eaux usées obtenu à partir de la pyrolyse d'une matière première et/ou du traitement d'une huile de pyrolyse avec une solution aqueuse dans laquelle la séparation de phase d'une solution aqueuse en un flux d'eaux usées a1' et une phase de déchets organiques o1 et par conséquent la teneur en carbone organique total (COT) du flux d'eaux usées, sont réduites. La réduction de la teneur en carbone organique total (COT) permet de simplifier le traitement des eaux usées et éventuellement de récupérer les molécules souhaitées dans ledit flux d'eaux usées.
