Abstract

Procédé de purification d'eaux résiduaires contenant des agents tensio-actifs, ainsi que des huiles et des graisses, selon lequel on ajuste à 2,5-3 avec de l'acide sulfurique le pH de l'eau résiduaire dans un réservoir, on introduit dans le milieu du charbon activé finement divisé, du KMnO4 , du MnSO4 et du CaCO3 , on mélange le tout mécaniquement ou par insufflation d'air pendant quelques minutes, on élève le pH 8,5-9 par une addition d'ammoniaque ou d'une solution de soude en agitant à nouveau le tout pendant quelques minutes, on laisse déposer pendant quelques heures la boue qui s'est formée et qui sera ultérieurement éliminée avec les déchets, et l'on continue de façon connue le traitement de l'eau surnageante.
