An improved filtration media, method of preparing the media, and method of treating a fluid stream with the media are disclosed. The improved media comprises a substrate having elevated levels of permanganate and water in one embodiment. More specifically, the improved media comprises a porous substrate impregnated with at least approximately 5 % permanganate, and at least approximately 10 % water, by weight. In another embodiment, the media further comprises sodium bicarbonate. Improved efficiency of removal of undesirable compounds such as hydrogen sulfide is achieved.
Milieu de filtration amélioré, son procédé de préparation et procédé de traitement d'un courant fluide par ce milieu. Dans l'une de ses variantes, le milieu amélioré comprend un substrat présentant des niveaux élevés de permanganate et d'eau, et plus précisément, il comporte un substrat poreux imprégné d'au moins environ 5 % de permanganate et d'au moins environ 10 % d'eau en poids. Dans une autre variante, il comporte de plus du bicarbonate de soude. On peut ainsi atteindre une plus grande efficacité dans l'élimination des composés indésirables tels que l'hydrogène sulfuré.
