A water softener removes the excess minerals out of water. There is a tank that has a tube that runs up and down. In the walls of the tube inside and the outer part of the tank are filters that filter out the minerals. The water is then pushed to your facet.

Most water softeners work through a process called ion exchange. In a nutshell, they take out the minerals in the water that make it hard (calcium and magnesium) and replace them with something that doesn't cause scaling and other problems (sodium or sometimes potassium).

Specifically, softeners filter water through resin beads packed with sodium. The hard water ions trade places with the sodium ions, leaving the water soft. Once the resin beads are depleted, they have to be regenerated. This is the purpose of water softener salt (sodium chloride or potassium chloride), and why it has to be continually added to conventional softeners.

There are also so-called "salt free water softeners." However, they don't technically soften water because they don't remove hard water minerals. Instead, they're designed to change water composition so that scaling and other problems do not occur.

If your goal is to have softer feeling and tasting water then a saltless softener will work just fine for you. With this softener, you are not actually removing salt, just changing the electric charge of the water.


Is ion-exchange resin a precipitating water softener?

No. Ion-exchange resin is used in the water treatment tank of a standard water softener. This type of water softener works by replacing water hardness ions, Calcium and Magnesium Ions, with either Sodium or Potasium ions. The hardness ions are not precipitated, but instead are electrostatically attracted to surface of the resin beads where they replace less tightly bound Sodium or Potassium ions. These Sodium or Potasium ions enter the water stream and leave the water softener in the softened water. In a standard water softener, also known as an ion-exchange softener, no precipitation takes place in the water softening process. (Precipitation is the formation of solids from a solution.)


Can the water taste salty in your water softener if the salt is low?
