How KDF Works

Typical Redox Reactions Harmful chlorine is removed by changing free chlorine into water-soluble chloride ions. KDF process media act as catalysts to change soluble ferrous cations into insoluble ferric hydroxide, which is easily removed by regular backwashing. KDF process media reduce hydrogen sulfide to insoluble cupric sulfide, which can be removed by backwashing.

KDF media employs 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.

What are KDF Process Media and how do they work?

KDF Process Media are high-purity, granulated copper and zinc-based alloys that treat water through a process based upon the principle of redox (Oxidation-Reduction). Originally, KDF was shorthand for Kinetic Degradation Fluxion.

We can explain redox like this: KDF Fluid Treatment’s unique combination of copper and zinc creates an electro-chemical reaction. During this reaction, electrons are transferred between molecules, and new elements are created. Some harmful contaminants are changed into harmless components. Free chlorine, for instance, is changed into benign, water-soluble chloride, which is then carried harmlessly through the water supply. Similarly, some heavy metals such as copper, lead, mercury and others, react to plate out onto the medium’s surface, thus being effectively removed from the water supply.
