GAC/KDF Filter Cartridges

GAC/KDF filter cartridges contain a blend of KDF and high activity de-dusted granular activated carbon (GAC) to give extremely effective and long life de-chlorination capacity, and can be used anywhere regular GAC’s are used. In addition to chlorine removal, KDF filters may be used for the removal of lead and heavy metals. The capacity will be approximately 20% of those listed for chlorine.

KDF short for Kinetic Degradation Fluxion Media is an artificial alloy of copper and zinc that has revolutionized water treatment. The copper in KDF has a positive charge while zinc has a negative, this results in an electrochemical oxidation-reduction reaction.

KDF is effective at removing or reducing the following

• Mercury
• Pesticides
• Arsenic
• liHydrogen sulfide
• Lead
• Chlorine
• Calcium
• Chromium
• Cadmium
• Aluminium
• Nickel
• Iron
• Rust
• Organic particles (thus removing smells and tastes)
• Limits growth or bacteria, algae, and fungi

The properties of KDF makes it an ideal pre-filtration medium, it is however expensive and for this reason we normally mix it with carbon to improve the effectiveness and life span of the carbon filters.
