KDF Fluid Treatment, Inc.
As with many inventions, combining copper and zinc to produce an electro-chemical reaction to remove free chlorine was an accidental discovery made by Don Heskett in 1984, which lead to the creation of KDF Fluid Treatment Inc.
Originally KDF was an acronym for Kinetic Degradation Fluxion. The discovery resulted in 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 its Standard 61 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 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 alloy 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 granulated activated carbon (GAC), controls and inhibits the growth of microorganisms and outperforms silver-impregnated carbon filters.
Used by major laboratories and manufacturers, KDF media is an ideal complement 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 <0.05 mg/l, which is 20 times below the acceptable EPA levels. Zinc levels are 0.46 mg/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.
As KDF Media does not remove fluoride, all OPUS Healthy Water System models designed for municipal water treatment include a fluoride filter. For microbiologically unsafe water (lakes, wells, etc., with high bacteria counts), ceramic filters, UV-C, ozonation, and ultra filtration technologies are recommended.
