Precautions for adding acid to reverse osmosis inlet water to prevent scaling
Hydrochloric acid and sulfuric acid can be added to the influent water to reduce the pH. Sulfuric acid is more commonly used than hydrochloric acid because it is cheap, does not emit smoke and corrodes surrounding metal components, and the membrane has a higher removal rate of sulfate ions than chlo...
