What is Water Softener Resin？

Water softener resin is the material that is necessary for the ion exchange process, which removes hard water minerals from your water.

Many people have heard of water softeners and may even have an ion exchange resin water softener, but most people don't know what exactly is meant by the terms "hard water" and "soft water."

Hard and soft water is defined by how much hardness is in the water. Hardness is composed of positively charged calcium (Ca++) and magnesium (Mg++) ions. The higher the concentration of these ions, the harder the water will be. This is important because hardness can form scale on hot surfaces such as water heater elements and boilers, and lead to system failure. When water is softened with Water Softener Resin, cations are removed and replaced with other cations that do not cause scale, namely sodium (Na+) or potassium (K+).

Ion Exchange Resin used in water softening applications can typically be used and regenerated for many years.
