KDF-85 drum (63 lbs.)
KDF-85: 1/3 cubic foot drum (63 lbs.) 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 patentedproducts 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.
The most critical aspect of pressure filter performance is the relationship of flow rate to surface of KDF-85 processmedium. 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 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/ft2Backwash for 10 min attwice the service flowPurge/rinse for 3 min attwice the service flowBed expansion, backwash10 to 15% Free board 20% Min. bed depth (6 dia)10PH range: drinking water 6.5 to 8.5.
