Water purification is extra than simply eradicating impurities — it’s about tailoring water to suit a goal. Two of probably the most extensively used strategies, distillation and deionization, obtain this aim in very other ways. Whereas each produce extremely purified water, they differ considerably in what they take away, how they function, and the place they’re finest utilized.
Distilled water is created by a easy however power-intensive course of: boiling water till it turns to steam, then condensing that vapor again into liquid. This leaves behind heavy metals, salts, and many contaminants, producing clear, mineral-free water.
