Abstract

L'invention a trait à un procédé de suppression, en ou partie, de la mousse contenue dans un milieu aqueux comprenant un ou plusieurs agents tensioactifs ou de prévention de formation d'une telle mousse dans un tel milieu comprenant une étape consistant à soumettre ledit milieu aqueux à l'action combinée d'une irradiation ultraviolette, de peroxyde d'hydrogène et d'un bullage d'air.The invention relates to a process for eliminating, in part or in part, the foam contained in an aqueous medium comprising one or more surfactants or for preventing the formation of such a foam in such a medium comprising a step consisting in subjecting said said medium. aqueous medium with the combined action of ultraviolet irradiation, hydrogen peroxide and air bubbling.
