A method for regenerating a weak base anion exchanger which comprises passing a regenerating chemical in an upward direction through a granular resinous mass of an exchanger, thereupon displacing the chemical and rinsing the mass with water. The regenerating chemical is a lime slurry having a concentration of 1 to 5% by weight, which is both supplied to and withdrawn from the granular mass in an evenly distributed flow with a flow rate of at least 10 m3, per hour, per m3 resin material (m3/h/m3), while the granular mass is in a compacted state.
