HOW A WATER SOFTENER WORKS
All water softeners use the same operating principle: They trade the minerals for sodium or potassium chloride, [salt chemcials]. The process is called ion exchange.
The heart of a water softener is a mineral tank. It's filled with small polystyrene beads, also known as resin or zeolite. The beads carry a negative charge.
In normal operation, hard water moves into the mineral tank and the calcium and magnesium ions move to the beads, replacing salt ions. The salt ions go into the water.
Hard water poses no health hazard. On the other hand, the salt that remains in softened water may be a problem for those on salt- restricted diets. (Ask your doctor)
