Bipolar Electrodialysis (BPED)
For recovery of brine streams to produce acid and caustic product
Bipolar Electrodialysis uses the basics of electrodialysis but introduces a bipolar membrane which splits water into H+ and OH- within an electrodialysis stack. BPED takes advantage of this process to either split salt streams into acid and caustic products or can adjust the pH of a process stream.
Veolia’s Ionics BPED can be used in several applications, including organic acid production, pH adjustment in beverages, or using industrial brine to generate value added acid and caustic byproducts.
