KDF Process Media

The MediaGuard Cartridge System provides for high-performance filtration in water softeners. Utilize KDF-55 in the MediaGuard System for reduction of chlorine and heavy metals. For reduction of
hydrogen sulfide and/or iron-laden water, use KDF-85 in the cartridge system.
     

KDF-55

KDF-55 granules are most effective in removing chlorine and water-soluble heavy metals.

KDF-55 Process Medium

KDF-55 process medium is an effective chlorine removal agent used in point-of-entry treatment of municipal water supplies. This unique, innovative and environmentally
responsible medium consists of high purity copper-zinc granules that use redox (the exchange of electrons) in patented products to effectively reduce/remove chlorine
and heavy metals and control microorganisms in potable water.

The most critical aspect of pressure filter performance is the relationship of flow rate to surface of KDF-55 process medium. Inaccurate sizing is the most common reason
for trouble in filter systems. The nominal flow rate in the service cycle depends on surface area available. Service flow rates with KDF-55 process medium, however, may
be calculated at 15 gpm per square foot of surface area. This is three times the effective flow rate of other filter media.

Recommended Operating Conditions:
Service flow (10" bed depth) 15 gpm/ft2
Backwash for 10 min @ twice the service flow
Purge/rinse for 3 min @ twice the service flow
Bed expansion, backwash 10 to 15%
Free board 20%
Min. bed depth (6" dia) 10"
PH range: drinking water 6.5 to 8.5
Water temperature, influent 35°F to 212°F

KDF-85 Process Medium

KDF-85 process medium is an effective iron(ferrous) and hydrogen sulfide (H2S) removal agent that may be used alone or to protect existing water filtration/purification
technologies in point-of-entry treatment of groundwater supplies. This unique, innovative and environmentally responsible medium consists of high purity copper-zinc granules
that use redox (the exchange of electrons) in patented products to effectively reduce/remove iron and hydrogen sulfide and heavy metals and control microorganisms in potable water. KDF-85 medium permits removal of iron and H2S without the use of chemicals.
