Mixed-bed deionizers are normally used to ‘polish’ the water to higher levels of purity after it has been initially treated by either a two-bed deionizer or a reverse osmosis unit.In mixed-bed deionizers the Strong Acid Cation and Strong Base Anion resins are closely mixed and contained in a single pressure vessel. The thorough mixture of resins in a single column makes a mixed-bed deionizer equivalent to anextended series of two-bed plants. As a result, the water quality obtained from a mixed-bed deionizer is appreciably higher than that produced by a two-bed plant.
