This is often the case in wastewater treatment, where sulfuric acid is often introduced to neutralize the pH or break emulsions. Sulfuric acid is sometimes also used in drinking water treatment facilities to remove impurities and create an improved taste. In oil refineries, it is often used as a catalyst in the creation of isooctane.
