What is water softening?

When water contains a high amount of calcium and magnesium, it is called hard water. Hard water is known to cause significant build up on critical heat transfer areas such as water heaters and dishwashers. Hard water reduces soap and detergent dissolving in water. Water softening is a technique that serves the removal of the ions that cause the water to be hard, in most cases calcium and magnesium ions. Iron ions may also be removed during softening.
