KDF 55 Filter Media - 1 LB

KDF-55 process medium is an effective chlorine removal, heavy metal removal , and a bacteriostatic 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 the 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: 15 gpm/sq. ft.- Backwash for 10 min. @: 30 gpm/sq. ft.- Purge/rinse for 3 min@: Maximum- Bed expansion, backwash: 10 to 15%- Free Board: 20%- Minimum Bed Depth (6" dia.): 10"- pH Range Drinking Water: 6.5 to 8.5- Water Temperature, influent: 35° - 212° F- Apparent Density: 171 pounds per cubic foot(Always maintain wetness)
