KDF Water Filter Media Provide Primary Water Treatment and Wastewater Treatment Solutions
What They Are and How They Work?
What is KDF Processed Media and how does it work?
KDF Processed Media is 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 with the water. 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 Media?
The marketplace is filled with good water filtration/purification systems and technologies.
So…why consider using KDF Media? We can give you two good reasons. One: Because KDF Media enhance the performance, extend the life, reduce the maintenance and lower the total cost of many available carbon-based systems. Two: KDF 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 Media results in the total elimination of some contaminants and a great reduction of a wide variety of others.
Benefits of KDF Media
- Significantly extend the life of granular activated carbon
- Are recyclable
- Effectively removes chlorine and heavy metals and controls microorganisms
- Are available in four granular styles, each designed for a specific need
- Outperforms silver-impregnated carbons
- Requires no EPA registration, thus less red tape
Where is KDF Media used?
KDF Media is 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. This is also why this media is very popular with shower filters.
Our Media is also used to replace silver-impregnated systems. Silver is more expensive than KDF Process Media.
