A relatively concentrated and a relatively dilute aqueous salt solution are respectively passed through the anode and cathode chambers of a flow-through electrochemical cell having a porous membrane separating the two chambers. The fluid pressure in the cathode chamber is maintained at less than atmospheric pressure and at less than the fluid pressure in the anode chamber while a potential difference is applied across the anode and cathode. In this way, dangerous build-up of gaseous electrolysis products in the chambers, especially the anode chamber, is avoided.
On fait passer une solution saline aqueuse relativement concentrée et une solution saline aqueuse relativement diluée à travers les chambres anodique et cathodique d'une cellule électrochimique de transfert possédant une membrane poreuse séparant les deux chambres. On maintient la pression du liquide dans la chambre cathodique à un niveau inférieur à la pression atmosphérique et inférieur à la pression du liquide dans la chambre anodique, tandis qu'on applique une différence de potentiel à l'anode et à la cathode. Ceci permet d'éviter la formation dangereuse de produits électrolytiques gazeux dans les chambres, en particulier, dans la chambre anodique.
