KDF® Process Media
KDF® process media are high-purity copper-zinc formulations used in pretreatment, primary treatment, and industrial applications. KDF water filter media supplement or replace existing technologies to dramatically extend system life, reduce heavy metals, microorganisms, scale, lower total cost, and decrease maintenance.
How It Works
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.
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
Why We Use KDF In Our LivingWaters™ Water Treatment Systems
First, even the best carbons, like the catalytic carbon stage that follows this KDF media, are susceptible to fouling from bacteria. Even though our Alkalizers™ employ technology certified to remove bacteria from the water coming INTO the system, bacteria in the air where the dispensing faucet is located can deposit themselves on the end of the faucet, and breed backwards down a water film that is present on any wetted surfaces. These bacteria can subsequently enter the chemical removing catalytic carbon bed that follows the stages that disinfect the water and begin to breed there. All water filters that use carbon suffer from this problem. The worst offenders are the faucet-mounted filters and filters used in refrigerator water and ice dispensers. Even though it is a common problem, most people don't know about it, so most manufacturers don't want to spend the money it takes to resolve the problem. We are not like most manufacturers, so we do. We use a bed of KDF®55 in every cartridge that keeps the carbon and other media that follows it bacteriostatic (bacteria can't breed in the media). It will also keep the water film that exists between the filter and the faucet free of bacteria as well. We think that is important.
Second, no other media is as effective at removing toxic metals like lead, and mercury from water. Lead is particularly dangerous and common in virtually all municipal water supplies. KDF also removes hydrogen sulfide (rotten-egg odor) from water. Because our drinking water system is only on your cold water supply to your sink, if you do ever smell that odor, you can know it is coming from your hot water side, and it is likely that your water heater anode needs replacement.
