KDF 85 Process Medium Removes Iron
Redox media alloys function as catalysts to change soluble ferrous cations (positively-charged ions) into insoluble ferric hydroxide, which can be removed with regular backwashing.
Redox media alloys function as catalysts to change soluble ferrous cations (positively-charged ions) into insoluble ferric hydroxide, which can be removed with regular backwashing. With enough oxygen dissolved in the water, iron removal rates of 98 percent or better are common.
