Abstract
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.
