Abstract

The present invention relates to a method of treatment of water comprising nitrate and/or nitrite, comprising the steps of adding an electrolyte to a water solution, allowing the water solution to pass through a flow reactor comprising at least a working cathode electrode and an counter anode electrode, thereby allowing the nitrate and/or nitrite to be reduced to nitrogen and/or ammonia, allowing any formed nitrogen to evaporate from the water solution, removing the formed ammonia from the water solution, and allowing the water solution to pass through at least a first sorbent to recover the electrolyte and optionally also through a second sorbent to remove any remaining nitrate and/or nitrite before collecting the purified water. A device for performing the method is also disclosed.
