I think the iron is reacted with prior to it reaching the carbon filter and that the carbon filter is mostly just a particle sieve with perhaps some amount of attraction. I don't think that backwashing regenerates in the same sense as softener resin. It just washes away the collected particulate. Maybe @ditttohead could give us a Reader's Digest explanation?If chlorine is adsorbed, and a ferrous ion comes by, does it react with the ion to make a ferric something?
