Lime in Water Treatment. Softening In water softening, hydrated lime is used to remove carbonate hardness from the water. Hardness caused by other calcium and magnesium salts, called noncarbonate hardness, is generally treated by means of the limesoda process, which entails the precipitation of magnesium by lime.
