A Combination of Ion Exchange and Electrochemical Reduction for Nitrate Removal from Drinking Water. Part I: Nitrate Removal Using a Selective Anion Exchanger in the Bicarbonate Form with Reuse of the Regenerant Solution.
Original language description
The process of selective nitrate removal from drinking water by means of ion exchange was studied. A commercial strong base anion exchanger with [triethylammonium]-N+Et3 functional groups was used in the bicarbonate (HCO3-) and [carbonate] CO32- form. The aim of this study was to optimize ion-exchanger regeneration in view of the subsequent electrochemical reduction of nitrates in the spent regenerant solution. The effects of ion-exchanger form, concentration of regenerant solution, and presence of nitrates, chlorides, and sulphates in the regenerant solution were studied. The strong base anion exchanger in HCO3- form that was investigated was able to treat 270 bed volumes of model water solution containing 124-mg dm-3 nitrates. To achieve adequate regeneration of the saturated anion exchanger it is necessary to use approximately 30 bed volumes of fresh 1-M [sodium bicarbonate] NaHCO3 regenerant solution. The presence of residual 50 mg dm-3 nitrates in the regenerant solution, treated
