ENTFERNUNG VON NITRAT |
摘要 |
A process for removal and destruction of dissolved nitrate from water containing the same, which comprises a removal step in the form of a nitrate selective anion-exchange operation; a destruction step for nitrate destruction by electrochemical reduction thereof; a conditioning step, where solution resulting from the destruction step is adjusted to a chloride concentration suitable for use of the solution as a regenerant in the anion-exchange operation; and a recycling step, where the solution resulting from the conditioning step is used as a regenerant in the anion-exchange operation. |
