A high capacity filtration media, method of preparing the media, and method of treating a fluid stream with the media are provided. The media contain a porous substrate impregnated with high concentrations of a permanganate. Preferably, the media includes a porous substrate impregnated with at least about 8% permanganate by weight. The media can optionally contain sodium bicarbonate. Improved capacity for the removal of undesirable compounds such as ethylene, formaldehyde, hydrogen sulfide and methyl mercaptan are achieved.
L'invention porte sur un milieu filtrant à forte capacité, sur son procédé de préparation, et sur un procédé de traitement de flux l'utilisant. Ledit milieu comporte un substrat poreux imprégné de permanganate à forte concentration, de préférence à raison d'au moins environ 8 % de son poids, et facultativement de bicarbonate de soude. On obtient ainsi une capacité accrue d'élimination de composés indésirables tels que l'éthylène, l'hydrogène sulfuré et le méthyl mercaptan.
