To achieve a cleaner production, textile wastewater with high organic and salt content can be treated by using Bipolar Membrane Electrodialysis (BMED) to minimize acid and base consumption in a dyeing process. While the dye molecules may foul the ion exchange membranes and strongly affect the desali...
