ABSTRACT:
Residual alkali metal ions from water, typically water having passed through a strong base demineralizer unit, may be removed by passing the water through a weak acid cation exchange resin, having a particle size distribution in which at least 90 weight percent of the resin has a particle size of at least 15 microns and at least 90 weight percent of the resin has a particle size of no more than 150 microns.
