Reticulated KDF Unique

Does it reduce scale or hardness?

CuZn Water’s patented KDF copper-zinc disks have several advantages over granular KDF. Our disks eliminate the need for backwashing, conserve water, reduce compaction, eliminate the need for cartridges and plastic waste, and are even recycleable. The disks are easier to use, maintain and refill than cartridge systems, plus they offer greater surface area for better performance.

Eliminates Hard Scale
Within a water system, calcium and magnesium can adhere to plumbing and water appliances by forming crystalline scale structures. These become hard, interfere with heat transfer and eventually cause loss of water flow and pressure.

Copper-zinc reshapes these hardness ions so they cannot adhere to each other or to the inside of plumbing. Instead the calcium and magnesium ions remain soluble in the water, thus reducing scale while adding life to the water.

(Water without these minerals is flat and can be aggressive, since water in its most natural state contains minerals such as calcium and magnesium, picked up from the earth as it filters through rock strata.)

This scale reduction feature is ideal for cooling towers, hot water heaters, water lines, plumbing, ice-makers, fountains, and other water-using equipment and appliances.

  • Combined with high quality carbon, the 2 medias can provide a simple, long life and high quality drinking water system


KDF is a patented product a major advancement in water treatment technology that works on basic process known as REDOX (oxidation/reduction) principles, representing a new and unique way of water processing medium which by its natural process of electrochemical oxidation/reduction and adsorption action reduces and/or removes many unwanted contaminants from water.

KDF medium is a versatile, specially formulated high purity, bimetal material. This product operates as a multifunctional medium which has superior capabilities of de-chlorination of drinking water and reduces dissolved heavy metals in water supplies.

The media inhibits bacteria growth (fungi, algae and mold) and reduces lime scale, mold, and fungi. throughout the entire unit. In fact, testing has shown that it reduces it up to 90%; thus eliminating the need for silver, commonly used in carbon-only filters. Silver is considered a pesticide by the EPA and, as such, must be registered with EPA.

Patented KDF media consists of a high purity copper-zinc formulation. These substances exchange electrons or bond with chlorine and other metals contained in the water to create harmless substances.

KDF is completely safe and meets EPA and FDA standards for levels of zinc and copper in potable water, so the process is not toxic and does not cause any adverse side effects.

  • What is KDF?
    Kinetic Degradation Fluxion (KDF) is a high-purity copper-zinc formulation that uses a basic process known as redox (oxidation/reduction) to remove chlorine, lead, mercury, iron, and hydrogen sulfide from water supplies.
  • How does KDF Work?
    In short, the KDF redox process works by exchanging electrons with contaminants. This “give and take” of electrons converts many contaminants into harmless components. During this reaction, electrons are transferred between molecules, and new elements are created. Some harmful contaminants are changed into harmless components. Others are electrochemically bound to the KDF media.
  • What Contaminants Does KDF Remove?
    KDF process media works to reduce or remove chlorine, iron, hydrogen sulfide, lead, mercury, calcium carbonate, magnesium, chromium, bacteria, algae, and fungi. Redox media removes up to 98% of water-soluble cations (positively-charged ions) of lead, mercury, copper, nickel, chromium, and other dissolved metals. In most cases, more than 98% of chlorine is removed if operated within recommended flow rates.
  • Will KDF remove Iron from the Water?
    Redox media alloys function as catalysts to change soluble ferrous cations (positively-charged ions) into insoluble ferric hydroxide, which can be removed with regular backwashing. With enough oxygen dissolved in the water, iron removal rates of 98 percent or better are common.
  • How Does KDF Remove Chlorine from the Water?
    High-purity copper-zinc redox media consistently remove 99% of free chlorine by electrochemically reducing dissolved chlorine gas to water-soluble chloride ions.
  • How does KDF Remove Hydrogen Sulfide from the Water?
    When hydrogen sulfide contaminated water enters the KDF filter, the copper in the KDF media loses an electron and the sulfur gains an electron and copper sulfide and water are formed. The copper sulfide is insoluble in water and can be backwashed off the KDF filter media
  • Will the KDF process media remove heavy metals such as lead from the water?
    KDF media remove up to 98% of water-soluble cations (positively-charged ions) of lead, mercury, copper, nickel, chromium, and other dissolved metals. When filtered through KDF media, soluble lead cations are reduced to insoluble lead atoms, which are electroplated onto the surface of the media. Other heavy metals bond to the media and may be recovered when the exhausted media pass through a copper smelter.
  • Will the KDF process media control microorganism growth in the water filters?
    KDF media are incorporated into carbon blocks and other matrices for bacteria control and scale reduction. The oxidation/reduction potential (ORP) shift by a factor of -300mV or more for water filtered through redox media controls microorganism growth. Treating water reduces bacteria and other microorganisms by disrupting electron transport, causing cellular damage. KDF process media also kill bacteria by direct electrochemical contact and by the flash formation of hydroxyl radicals and hydrogen peroxide, both of which interfere with a microorganism’s ability to function.
  • Will the KDF filter systems add any toxic substances to the water?
    KDF process media are completely safe. KDF media meet EPA and Food and Drug Administration standards for levels of zinc and copper in potable water, so the process is not toxic and does not cause any adverse side effects. You may not even realize that KDF process media are working for you. KDF edia is the core product of many filtration systems, and can be used in conjunction with other products to provide superior purification.
