KDF Technology:
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.
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.
Why use KDF Process Media?
The marketplace is filled with good water filtration/purification systems and technologies (We should know—many of those manufacturers are some of our best customers.)
So…why consider using KDF Process Media? We can give you two good reasons:
#1) Because KDF Process Media enhance the performance, extend the life, reduce the maintenance and lower the total cost of many available carbon-based systems.
#2) KDF Process Media help control microorganisms by creating an environment that’s deadly to some microorganisms and that interferes with the ability of many other microorganisms to function. Either way, the use of KDF Process Media results in the total elimination of some contaminants and a great reduction of a wide variety of others.
Benefits of KDF Process Media
- Significantly extend the life of granular activated carbon
- Are recyclable
- Effectively remove chlorine and heavy metals and control microorganisms
- Are available in four granular styles, each designed for a specific need
- Outperform silver-impregnated carbons
- Require no EPA registration, thus less red tape
KDF 55 Process Medium controls microorganisms and reduces lime scale in problem areas like showers and tubs. KDF 55 Process Medium even changes waterborne calcium molecules that inhibit scale buildup in showers.
Ahead of the Carbon, Ahead of the Game
KDF 55 Process Medium is truly bacteriostatic. The electrolytic field created by the redox process is an environment deadly to microorganisms; it also creates hydroxyl radicals and hydrogen peroxides that interfere with the ability of some other microorganisms to function.
KDF 55 Process Medium is non-toxic, completely safe. It meets USEPA and US Food and Drug Administration (USFDA) standards for levels of zinc and copper in potable water.
KDF 55 Process Medium Improves The Performance Of Shower Filters
At higher water temperatures, such as used for showering, the very capacity of GAC that makes it so effective and desirable in a water filtration system (trapping odor-causing contaminants, including chlorine) works against it in the shower. Higher temperatures can cause some contaminants trapped in the carbon bed to re-enter the water flow. Hot water, however, has no such effect on KDF 55 Process Medium. In fact, the higher the water temperature, the more effective KDF 55 Process Medium becomes in reducing free chlorine.
