KDF Origins and Description
As with many inventions, combining copper and zinc to provide an electro-chemical reaction to remove free chlorine was an accidental discovery made by Don Heskett in 1984, which led to the creation of KDF Fluid Treatment Inc.
Originally KDF was an acronym for Kinetic Degradation Fluxion. The discovery let to many patents and opened up a new era in water treatment. In 1992, KDF 85 and KDF 55 Process Media were certified by NSF international to it’s Standard 61 for for drinking water. In 1997, KDF Fluid Treatment became a member of the Water Quality Association, receiving ANSI/NSF Standard 42 certification for drinking water. KDF media combined with GAC (Granulated Activated Carbon) can be used in point of entry (whole house) systems and point of use (drinking water) systems.
Using a process of electro-chemical oxidation known as redox (Oxidation Reduction) KDF media is a zinc-copper allow that removes 99.9% of free chlorine, heavy metals, nitrates, nitrites, silver, aluminum, arsenic, cadmium, copper, iron, nickel, zinc, lead, chromium, barium, hydrogen sulfide, radon, selenium, trihalomethanes, manganese, mercury, chloroform, trichlorethane, lindane, pesticides, fungicides, bad tastes and odors. KDF media significantly extends the life of GAC, controls and inhibits the growth of microorganisms and outperforms silver-impregnated carbon filters.
Used by major laboratories and manufactures, KDF media is an ideal compliment to activated carbon filters. The high purity zinc-copper alloy, known as KDF-55D, produces zinc oxide, which destroys bacteria, extending the life of activated carbon while limiting the growth of bacteria in the carbon bed. The zinc-copper alloy attracts heavy metals like a magnet. Testing confirms that the level of copper in water filtered by KDF media is less than 0.05mg/L which is 20 times below the acceptable EPA levels. Zinc levels are 0.46mg/L, over ten times below the EPA safety level of 5.0 mg/L.
There is no better technology for the removal of contaminants from microbiologically safe water than KDF combined with GAC.
