Well pumps raw water to top ...

Well pumps raw water to top of and falls through a forced air degasifier filled with media into a clear well where iron settles out before transfer pumps move water in piping with a form of flow proportional chlorine injection to ground or elevated storage tanks then pumped to distribution system.  The water could also transfer to other treatment processes/mechanisms before the storage tanks, as needed for quality.  We find the forced air and media with chlorine disinfectant sufficient to achieve our iron reduction for our public water plant.  At my house on a private well I pump through marble chips & MgO then through softene/r resin tank to get my high iron down for taste, while others simply use aerator tank before house pump (which is why central floridians love sweet tea to hide iron color & taste...LOL).
