The use of caustic soda instead of lime may reduce calcium carbonate precipitation while achieving the desired finished water pH. However, the benefit of using caustic soda over lime can be realized only under certain water quality conditions. Generally, caustic soda provides some benefit over lime for soft waters. The benefit of caustic over lime decreases as the calcium hardness increases.
