Electrodialysis technology was used to remove the melassigenic ions of mother liquor of beet sugar and beet sugar syrup, obtained from the Moroccan sugar industry. The operations were conducted using an electrodialysis pilot plant equipped with two ions exchange membrane with high temperature and organic resistance first on mother liquor diluted at 25% with water and juices and secondly on beet sugar syrup at two higher Brix (52 and 60 Bx). The performances of the electrodialysis operation were evaluated and the best operation conditions were determined. This study confirms the effectiveness and the efficiency of the ED process to reduce melassigenic ions for beet sugar solution.
