Description
Iron manganese media, used for removing soluble iron (Fe) and/or manganese (Mg) as well as hydrogen sulfide (H2S) from well water supplies, is a purple-black filter media processed from ceramic zeolite granule. Iron manganese media can be used in a completely closed pressure system with no aeration or re-pumping, or in an open gravity filter system.Physical Characteristics

Methods of Operation
Continuous regeneration:Continuous regeneration operation is recommended for well water where iron removal is the main objective with or without the presence of manganese. Briefly, it involves the feeding of predetermined amount of potassium permanganate ( KMnO4 ), usually in combination with chlorine ( Cl2 ), directly to the raw water prior to the unit containing Iron manganese continuous regeneration. The chlorine should be fed upstream of the KMnO4 with a contact time of 10 ~ 20 seconds if possible. Sufficient chlorine should be fed to produce the desired residual in the filter effluent. Enough KMnO4 should be fed to produce a “just pink” color in the filter inlet. This will maintain the Iron manganese n media in a continuously regenerated condition.
The quantity of Cl2 and KMnO4 required can be estimated as follows: mg/L Cl2 = mg/L Fe mg/L KMnO4 = (0.2 x mg/L Fe)(2 x mg/L Mn) Without Cl2 the KMnO4 demand can be estimated as follows: mg/L KMnO4 = (1 x mg/L Fe)(2 x mg/L Mn)
Suggested Operating Conditions
Backwash: Sufficient rate using treated water to produce approximately 30% bed expansion.
Capacity: 350~500 g/m2 of bed area based on potassium permanganate demand. For iron/manganese continuous regeneration, a 70cm minimum bed of specially sized iron/manganese media is required. Pressure drop should not exceed 0.70 ~ 0.85 kg/cm2.
Flow rate: Normal flow rates with continuous regeneration operation is approximately 5 ~ 12 m/hr. Higher concentrations of iron and manganese usually require lower flow rates for equivalent run lengths. Rates in excess of 12 m/hr can usually be tolerated but a pilot unit should be operated to determine the effluent quality and run length.
The run length between backwashes can be estimated as follows:
The run length between backwashes can be estimated as follows:
Example:What is run length on a water containing 1.7 mg/L iron and 0.3 mg/L manganese at 10m/hr operating rate? KMnO4 demand = (1 x mg/L Fe)+(2 x mg/L Mn) =(1 x 1.7) + (2 x 0.3) = 2.3 mg/L At 500 g/m2 loading ÷ 2.3 mg/L = 217 m At 10 m/hr service rate, 217/10 = 21.7 hr Therefore the backwash frequency is approximately every 20 ~ 24 hours of operation.
