KDF®-55 is a high-purity copper-zinc process media that is offered in granule form, with coarse, fine, and extra-fine mesh sizes. It is non-toxic, 100% recyclable, and contains no chemical additives. It removes chlorine and soluble heavy metals while controlling scale, bacteria, and algae—even in hot water.
KDF®-55 medium can remove over 99% of free chlorine, enhance granular activated carbon systems to more effectively remove organic contaminants, extend the useful service life by up to 15 times, and reduce chlorine removal costs by over 50%. As GAC removes chlorine by surface chemistry, it fosters bacterial growth. KDF® is a true bacteriostatic whether the filter is active or inactive, and when used in combination, it creates an environment deadly to many microorganisms. By reducing inorganic contaminants before they get to the carbon bed, KDF®-55 Process Medium protects GAC from bacterial fouling and bacterial buildup, thus reserving the adsorption capacity of GAC for removing organic contaminants.
