     Optimal conditions for carrying out the electrodialysis of the Moroccan cane sugar juice to remove melassigenic ions are determined. The variations of juice parameters (cations contents, ash contents, juice pH and decoloration rate) with electrodialysis parameters (time, flow rates, temperatures, voltages) are followed. A thermostability test of the treated juice was carried out to control its behaviour towards temperature.
