Abstract: In a counterflow moving bed type ion exchange apparatus in which an ion exchange resin is supplied to the upper portion of a column and a liquid being treated is supplied to the bottom of the column to flow upwardly through the moving resin bed, liquid jets are used to separate a predetermined quantity of the spent resin from the moving resin bed. The separated resin is circulated through a regenerating system including a washing column and a counterflow type regenerating column.
