Catalytic Carbon is a substance that has a long history of being used to absorb impurities and is perhaps the most powerful absorbent known to man. One pound of carbon contains a surface area of roughly 125 acres and can absorb literally thousands of different chemicals. Carbon which has a slight electro-positive charge added to it, making it even more attractive to chemicals and impurities. As the water passes over the positively charged carbon surface, the negative ions of the of the contaminants are drawn to the surface of the carbon granules. Catalytic carbon is highly effective with iron, hydrogen sulfide, chloramines and chlorine. KDF Media when used in conjunction with the finest grade Carbon, gives you the best water filter media to eliminate contaminants in your water supply. 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 water filter media extend the life of granular activated carbon (GAC) while protecting the carbon bed against fouling by bacterial growth. Because KDF does most of the heavy lifting in removing contaminants, the carbon lasts much longer. The carbon is used then to mainly "polish" the water to give it a sparkling taste. KDF 85 Removes or reduces iron, chloramines, and hydrogen sulfide from municipal or other water supplies. Also controls scale, bacteria and algae.Benefits of KDF Process MediaSignificantly extend the life of granular activated carbonAre recyclableEffectively remove chlorine and heavy metals, iron, hydrogen sulfide, and controls scale and microorganismsAre available in four granular styles, each designed for a specific needOutperform silver-impregnated carbonsRequire no EPA registration, thus less red tape Track Page Views With Auctiva's FREE Counter
