Dealkalizers & Deionizers
Chloride Anion Dealkalizers are primarily used for the removal of alkalinity from boiler feed water. Removal of the alkalinity prevents insoluble carbonate precipitates from forming in the boiler tubes and stops corrosion, which may be due to carbonic acid formation. Dealkalization by ion exchange uses strong base anion resin and will remove 90-95% of carbonate and bicarbonate alkalinity as well as 99% of the sulfates, nitrates and fluoride when regenerated with salt only. It will remove all of the CO2 and give higher capacities when regenerated with both salt and sodium hydroxide.
