Water hardness
Water containing high amounts of calcium and magnesium minerals is ‘hard water’. The amount of hardness in natural water can vary from a few ppm to 500 ppm. Calcium and magnesium compounds are relatively insoluble in water and tend to precipitate out. This causes scale and deposit problems. Such water must be treated to make it suitable for steam generation.
