摘要
An advantageous industrial procedure for the removal of ions from an aqueous feed solution is accomplished in a system having a column containing a bed of mixed anion and cation exchange resins wherein the bed is capable of moving upward or downward en masse in the column. The feed solution is passed upward through the column causing the bed to tend to move upward en masse and eventually exhausting the exchange resin. Then, an aqueous stripping solution is passed downward through the bed to remove the ions from the exchange resin and causing the bed to tend to move downward en masse. Thereafter, the exchange resins are regenerated and the procedure is repeated.
