This percentage is growing steadily year-on-year. Formation: Minerals and salts are dissolved from rocks and soil An expected investment of US$10 billion over the next five through weathering processes and transported by water years is projected to add 5.7 million cubic meters per day of bodies. new desalination production capacity. Importance: Minerals and salts regulate water chemistry, support By 2030, this capacity is anticipated to double. aquatic life, and have various industrial applications. In Saudi Arabia, water desalination has doubled over the past decade, reaching 2.2 billion cubic meters in 2021, up from 1.1 billion cubic meters per year in 2010. This achievement is attributed to plant upgrades and the adoption of new technologies.
