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.

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. 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 Hazardous Material registration

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.

What about KDF Process Media and RO, DI and IX systems?

Reverse Osmosis (RO), Deionization (DI) and Ion Exchange (IX) systems benefit from the use of KDF Process Media because our Media allow these systems to tend to their strengths. Our Media protect RO systems from chlorine degradation and bacterial contamination, extending the life of the systems’ membranes. KDF Process Media protect expensive IX systems from becoming fouled with chlorine, algae, fungi and bacteria. Less fouling, longer life and reduced maintenance, all combine for lower costs.

KDF Lab Test Results from Biological Research Solutions

Laboratory Service Performed: Analysis of the mode of action of KDF versus Pseudomonas fluorescens.

Table 1- Testing Protocol

All water used for testing was deionized and injected with AOAC synthetic hard water to a final concentration of 100 ppm and a pH 7.0 +/-.2

Following collection, the samples were surface plated on Plate Count Agar within 2 to 3 minutes of collection and again after incubation at room temperature for 3 hours.

The same inoculums of Pseudomonas fluorescens was used for injection in to Samples 3 and 4 or for addition to Samples 1 and 2 (added after collection of the water).

Customer: Systematix Inc.
Sample Date: 3-23-90
Report Date: 5-04-90
Sample ID: 9003-1233B Di-Tech KDC+1.5
Subject: One Systematix 9-3/4" filter cartridge was received for testing to determine its ability to remove heavy metals from water.
Method: Reagent grade lead chloride was spiked into drinking water and run through the filter per manufacture and NSF specifications. The influent and effluent water were tested per EPA Methods for Chemical Analysis of Water and Waste (EPA-600/4-79-020).
