Founded in 1984, KDF Fluid Treatment Inc. is a technological leader in the fluid treatment industry. Beginning with a U.S. patent for KDF redox alloy media in 1987, the company continues its technological innovation.
KDF Process Media are used in pretreatment, primary treatment and process water applications. KDF media supplement or replace existing technologies to dramatically extend system life, lower total cost and decrease maintenance. Patented KDF Process Media are 100% recyclable and contain no chemical additives. Hospitals, restaurants, municipal water treatment facilities and homes rely on KDF media to safely reduce or remove chlorine, iron, hydrogen sulfide, heavy metals and bacteria from their water. KDF is certified to NSF International Standard 61 and to ANSI/NSF Standard 42 for drinking water.
KDF Process Media are high-purity, granulated copper and zinc-based alloys that treat water through a process based upon the principle of redox (oxidation-reduction): 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.
KDF Fluid Treatment Inc.  offers two product lines of media, KDF 55 Process Medium  and KDF 85 Process Medium  , which can remove up to 99% of water-soluble lead, mercury, nickel, chromium and other dissolved metals.
KDF Process Media enhance the performance, extend the life, reduce the maintenance and lower the total cost of many available carbon-based systems. The media also help control microorganisms by creating an environment that is hostile to some microorganisms and that interferes with the ability of many other microorganisms to function. The use of KDF Process Media results in the total elimination of some contaminants and a great reduction of a wide variety of others.
KDF Process Media from KDF Fluid Treatment Inc.  are antimicrobial. The U.S. Environmental Protection Agency (EPA) approved copper alloys as antimicrobial, making the copper- and zinc-based KDF Process Media antimicrobial as well. The EPA approved the registration after laboratory tests confirmed that copper alloys eliminate more than 99.9% of bacterial contamination within two hours of exposure.
KDF media can remove up to 99% of water-soluble lead, mercury, nickel, chromium and other dissolved metals. Effective in controlling buildup of bacteria, algae, fungi and scale, these media are ideal for GAC beds, ion exchange resins, carbon block filters and inline carbon filters. KDF media are used for both for point-of-entry (POE) and point-of-use (POU) water treatment systems.
