A process for sour water treatment in which the sour components are removed from a sour water stream in an electrodialysis step in which the sour water stream becomes the dilute stream. A resulting concentrate stream, richer in the sour components than the original stream is then steam stripped. In order to balance the acid and basic components in the dilute stream the component lacking may be added to the stream. In order to prevent build-up of non-strippable components in the concentrate stream a part of the latter is recombined with the dilute stream either before or after the electrodialysis step.
