KDF-85 filter media are high-purity copper-zinc granules that reduce contaminants in water using oxidation/reduction(redox) reaction. KDF 85 process medium is an effective iron(ferrous) and hydrogen sulfide (H2S)removal agent that may be used alone or to protect existing water filtration/purification technologies in POE treatment of groundwater supplies.These unique, innovative and environmentally responsible media consist of high purity copper-zinc granules that use redox(the exchange of electrons) in patented products to effectively reduce/remove chlorine, iron, hydrogen sulfide, heavy metals, and control microorganisms in potable water without the use of chemicals.What’s more, KDF 85 media is highly efficient and tank size requirements are modest for more economical system engineering and installation. For potable water service flows in a range from 3 to324 gallons per minute with maximum chlorine, iron, and H2S concentrations of 5 ppm/mgl
Patented KDF Process Media are 100% recyclable and contain no chemical additives. KDF-85 Medium is classified as a "pesticidal device" by the US Environmental Protection Agency so no pesticidal registration is required. KDF-85 Media also meets EPA and Food and Drug Administration standards for maximum limits of zinc and copper in potable water.
