Dealkalizers can remove more than 90% of the bicarbonate alkalinity in a softened water supply. High alkalinity contributes to boiler foaming and carryover as well as excessive blowoff rates. Besides improving water chemistry in the boiler, lowering alkalinity reduces formation of carbon dioxide in the system, which is the major cause of condensate piping corrosion.
