Calcium and magnesium provide hardness in a solution. By itself, hardness does not present any problems. A calcium solution at a pH of 3 may have hardness, but it is not going to scale. This Section looks at the scaling or precipitation fouling that results when alkalinity is present with the hardness and how this scaling forms on heat-transfer surfaces in cooling systems.
