| 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 by electrolysis,
