Zusammenfassung:A process for the removal and destruction of dissolved nitrate from water, which comprises a removal step where nitrate is eliminated from said water or effluent in the form of a more concentrated solution thereof, and a destruction step where said more concentrated nitrate solution is subjected to an electrolysis operation for nitrate destruction by electrochemical reduction thereof, the electrolysis operation being performed in several cycles in a divided cell with anolyte and catholyte compartments, where said concentrated nitrate solution is initially used as a catholyte and spent catholyte is then used as an anolyte. An apparatus suitable for performing such a process.
