KDF- How it works

What is KDF Media and how does it work? 

                              

Water Filter Media for Primary Water Treatment and Industrial Treatment.

KDF Process Media is used for a variety of pretreatment, primary water treatment, and industrial treatment processes. It is used in place of, or in conjunction with, granular activated carbon filters, even carbon block or inline filters. KDF water filter media extends the life of granular activated carbon (GAC) while protecting the carbon bed against fouling by bacterial growth.

KDF media is also used to replace silver-impregnated systems. Silver is toxic however KDF Process Media are not. Silver must be registered with the EPA as a toxic pesticide, KDF Process Media does not.

Redox (oxidation reduction process): 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.

Why use KDF Process Media?

KDF Process Media enhances performance, extends the life, reduces the maintenance and lowers the total cost of many available carbon-based systems. KDF Process Media help control microorganisms by creating an environment that's deadly to some microorganisms and that interferes with the ability of many other microorganisms to function. Either way, the use of KDF Process Media results in the total elimination of some contaminants and a great reduction of a wide variety of others.

Benefits of KDF Process Media

* Extends the life of granular activated carbon
* Recyclable
* Effectively remove chlorine and heavy metals and control microorganisms
* Available in four granular styles, each designed for a specific need
* Outperform silver-impregnated carbons (Require no EPA registration)

Note: Gulf South Research Institute found silver-impregnated carbon provides the same performance as activated carbon, except in low pH water.

* With proper handling
