Abstract
A method of removing contaminants from water filtration media is disclosed, including (a) applying a granular cleaner to the water filtration media, and (b) after step (a), applying multiple discrete doses of an activator to the water filtration media at predetermined time intervals. Further disclosed is a method of cleaning water filtration media, including (a) applying a granular cleaner to the water filtration media that is reactive with at least one first inorganic contaminant; (b) after step (a), applying a liquid cleaner to the water filtration media that is compositionally different from the granular cleaner and reactive with at least one second inorganic contaminant; and (c) after step (b), applying an activator to the water filtration media that is reactive with an organic contaminant. A method of cleaning water filtration media is also disclosed including agitating at least a portion of the water filtration media.
