PROCESS FOR THE REGENERATION BY BY LEADING ANIONS, IN PARTICULAR NITROGEN ION CONTAINING WATER, THE bicarbonate ANIONENWISSELHARSEN EXHAUSTED AND APPLICATION OF THE REGENERATED ANIONENWISSELHARSEN.

摘要

The object of the invention is a process for the regeneration of anion exchanger resins, exhausted by passing through water containing anions, in particular nitrate ions, to the bicarbonate form by treatment thereof with an electrolyte containing bicarbonate ions, in which, prior to the treatment with the electrolyte containing bicarbonate ions, a treatment is carried out with an electrolyte containing chloride ions. …??The object of the invention is also the use of the abovementioned regenerated anion exchanger resins for eliminating the anion content, in particular the nitrate content, from water, in particular from bodies of water.
