Application of the bipolar electrodialysis technique for the production of hydrochloric acid from wastewater regeneration of ion exchange resins

Xavier Cordova, Jhonny Valverde Flores


This research had as a goal to determine how the application of bipolar electrodialysis technique influences the production of hydrochloric acid, regeneration of ion exchange resins from wastewater in the urbanization Enace – Carabayllo, Lima, Peru. The technique used was electrodialysis bipolar. For this, the bipolar electrodialysis module was constructed at laboratory scale with the purpose of recovering the chlorine ion (Cl-) for the production of hydrochloric acid and the recovery of the sodium ion (Na +) to obtain a sub product as is the sodium hydroxide from residual regeneration water of ion exchange resins. The controllable factors were considered as: voltage applied to the electrodialysis cell (6, 12, 18 V), and feed flow (300 mL/min, 600 mL/min). A recovery after of 200 minutes, 18 volts and a flow of 600mL/min was achieved a percentage of 84.91% of chlorine ion for the production of hydrochloric acid and 39.02% of sodium ion for a by-product of sodium hydroxide.
