KDF process media are high-purity copper-zinc granules used in a number of pre-treatment, primary treatment, and wastewater treatment applications. KDF media supplement or replace existing technologies to dramatically extend life of the system, control heavy metals and microorganisms, lower total cost, and decrease maintenance. KDF process media work to reduce or remove chlorine, iron, hydrogen sulfide, lead, mercury, calcium carbonate, magnesium, chromium, bacteria, algae, and fungi.

KDF media utilize an old process in a new way-the oxidation and reduction of ions, known as redox. In short, the redox process works by exchanging electrons with contaminants. This give and take of electrons converts many harmful contaminants into harmless components, such as chlorine to chloride. Other contaminants, including heavy metals, bond to the KDF media, which greatly reduces or virtually eliminates these substances.

KDF process media control microorganisms in two ways. The first is a by-product of redox; the exchange of electrons sets up an electrolytic field in which most microorganisms can't survive. Second, the process of forming hydroxyl radicals and peroxides from some of the water molecules interferes with the microorganisms' ability to function.
