Abstract (en)
[origin: CA2691535A1] The invention relates, in particular, to a process for treating a liquid medium loaded with nitrates via a chemical route that mainly comprises a step of electrolysis of the liquid medium in the presence of a metal salt, the electrolysis being carried out at a pH below 5. The invention also relates to a device for treating a liquid medium loaded with nitrates and also to the applications of this process and device, in particular for reducing the level of nitrates in drainage waters.
