Softening with cation resin is a simple exchange function. The IX resin bead is negatively charged and attracts positive ions. When supplied in the sodium form (Na+) the resin will exchange sodium ions for hardness ions calcium and magnesium. The bead is more strongly attracted to these ions and readily exchanges with the sodium.Once the resin is exhausted it is regenerated with a brine solution (NaCl). The brine overwhelms and releases the calcium and magnesium from the bead. The resin is converted back to the sodium form and ready for re-use.
Demineralization generally results in almost complete removal of minerals, and is thus typically reserved for applications requiring higher level of water purity, such as feed or makeup water for high pressure boilers, rinse water for food and beverage industries, or process streams used in electronics manufacture, for example.
