Hi Annette,

    I'm not sure of all the chemistry involved.  But an over simplified
    explanation is, the calcium (& other minerals) in the raw water are
    exchanged with sodium ions in the resin bed. The 'hard' minerals are
    then removed from the resin bed during regeneration by the brine
    solution. The resin bed retains the sodium ions & the 'hard' minerals
    are dumped with the brine used for regeneration.
