Electrodialysis

Membranes, Stacks, and Systems for desalination of brackish water, and demineralization of process streams, and salt splitting applications

• Veolia's portfolio of ion exchange membranes and electrodialysis solutions including:
• Electrodialysis (ED) for value-added demineralization of process streams
• Electrodiaylsis Reversal (EDR) for high recovery desalination of brackish waters
• Bipolar Electrodialysis (BPED) for brine recovery to produce acid and caustic
• Electro Dialysis (ED) is a membrane process, during which ions are transported through semi permeable membrane, under the influence of an electric potential. The membranes are cation- or anion-selective, which basically means that either positive ions or negative ions will flow through. Cation-selective membranes are polyelectrolytes with negatively charged matter, which rejects negatively charged ions and allows positively charged ions to flow through.
