Specifications:

• KDF-55: 1/3 cubic foot drum (63 lbs.) KDF-55 process medium is an effective chlorine removal agent used in point-of-entry treatment of municipal water supplies or other chlorinated water supplies.
• This unique, innovative and environmentally responsible medium consists of high purity copper-zinc granules that use redox (the exchange of electrons) in to effectively reduce/remove chlorine and heavy metals and control microorganisms in potablewater.
• The most critical aspect of pressure filter performance is the relationship of flow rate to surface of KDF-55 processmedium.
• Inaccurate sizing is the most common reason for trouble in filter systems.
• The nominal flow rate in the serv-ice cycle depends on surface area available.
• Service flowrates 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
