BL 211 is a concentrated pure alkali solution, used to raise the pH and maintain the alkalinity of the feed water and boiler water. Feed water pH adjustment is needed to control pipeline corrosion. Boiler water alkalinity is required to cause precipitation of calcium and magnesium hardness, as calcium hydroxyapatite and serpentine desired sludge and minimizes corrosion in the boiler waterside.
