The process of adding minerals back into water involves introducing naturally occurring or manufactured mineral compounds. This restores the mineral content lost during certain water treatment processes such as reverse osmosis, distillation, or deionization. For instance, adding calcium carbonate or magnesium sulfate to purified water increases its mineral concentration.
Restoring minerals enhances the taste, improves the pH balance, and potentially contributes to certain health benefits. Historically, mineral springs have been valued for their purported therapeutic properties. In modern contexts, the practice is crucial in ensuring that drinking water is not only pure but also contains essential nutrients necessary for optimal hydration and wellbeing.
