KDF Water Filter Media Provide Primary Water Treatment and Wastewater Treatment Solutions

What They Are and How They Work?

 

What are KDF® Process Media
and how do they work?

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). Originally, KDF was shorthand for Kinetic Degradation Fluxion.

We can explain redox like this: 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?

The marketplace is filled with good water filtration/purification systems and technologies (We should know—many of those manufacturers are some of our best customers.)

So…why consider using KDF Process Media? We can give you two good reasons (See " Benefits of KDF Process Media " below). One: Because KDF Process Media enhance the performance, extend the life, reduce the maintenance and lower the total cost of many available carbon-based systems. Two: 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

  • 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

Where are KDF Process Media used?

KDF Process Media are used in a variety of pretreatment, primary treatment, and wastewater applications. They are generally used in place of, or in conjunction with, granular activated carbon filters, even carbon block or inline filters. KDF Process Media extend the life of granular activated carbon (GAC) while protecting the carbon bed against fouling by bacterial growth.

Our Media are also used to replace silver-impregnated systems. Silver is toxic, KDF Process Media are not. Silver must be registered with the EPA as a toxic pesticide, KDF Process Media do not. By the way, silver is more expensive than KDF Process Media.
