Abstract: Procédé de traitement de l'eau contenant des sulfures, consistant à oxyder les sulfures dans un réacteur en milieu aérobie ayant une charge minimale de boue contenant des sulfures. La charge minimale de sulfures est égale à au moins 10 mg de sulfures par mg d'azote présent dans la boue par heure, la charge de boue étant calculée en fonction de la partie de la biomasse oxydant les sulfures. La charge minimale de sulfures peut aussi être définie comme étant égale à 25 mg de sulfures par litre de matière dans le réacteur par heure. Les sulfures peuvent être largement oxydés en soufre élémentaire qui est alors séparé et réutilisé. Les eaux usées contenant également de la matière organique en plus des diverses teneurs en sulfures sont purifiées sans intervention de bactéries filamenteuses au moyen d'un processus en deux étapes en milieu aérobie. Le processus d'élimination des sulfures peut être utilisé pour le traitement des eaux usées ayant des teneurs élevées en composés soufrés comme des sulfates, des sulfites et des thiosulfates en réduisant d'abord ces composés soufrés dans une étape aérobie. Les métaux lourds sont éliminés de l'eau par addition des sulfures à l'eau et par précipitation des métaux sous forme de sulfures; les sulfures peuvent être ajoutés par réduction des composés soufrés déjà présents.
