Chemical Reaction in Filters with KDF® Process Media

KDF® media donating two negatively charged electrons to each molecule of chlorine to reduce it to the lower oxidation state of chloride. Chloride are highly soluble and innocuous molecules that don't possess oxidation properties any longer.

KDF Media can remove up to 99% of water-soluble lead, mercury, nickel, chromium, and other dissolved metals. All KDF Process Media forms are effective in controlling the buildup of bacteria, algae, fungi and scale, making them ideal for use in GAC beds, ion exchange resins, carbon block filters and inline carbon filters. Wherever our Media are used, they can eliminate the need for costly, and sometimes harmful, chemical treatments.
