Understanding Sodium Hypochlorite | Treatment Plant Operator

When sodium hypochlorite is used, acetic or sulfuric acid is added to the water. An excessive dose can produce poisonous gases. If the dosage is too low, the pH becomes too high, and it can irritate the eyes. The required concentration of sodium hypochlorite depends on the concentrations of pollutants, primarily organic pollutants.
