SOFTENER​ SYSTEMS

Water softening process is a typical ion exchange method. Ion exchange is accomplished by passing water having suitable velocity through the resin bed and Na+ inside the resin will be exchanged with Ca 2+ and Mg2+ in the inlet water that cause hardness. After certain amount of time or quantity of water passed through resin media, resin particles are completely covered with hardness minerals. At this time a regeneration step is required to continue softening process. In regeneration step, brine solution will be given over the resin, calcium (Ca2+) and Magnesium (Mg2+) ions leave the resin and sodium (Na+) ions again combine to resin due to affinity and the resin will be ready for the
next service.
