Bipolar Membrane Electrodialyzer BPED

The bipolar ion exchange membrane electrodialysis is an electrodialysis formed by combining bipolar membranes and unipolar membranes in different ways. Bipolar membrane electrodialysis combines the dissociation of salts of ordinary electrodialysis with the dissociation of H2O molecules in bipolar membranes. In this way, the corresponding salt ions in the solution combine with the hydrogen ions and hydroxide ions generated by the hydrolysis of the bipolar membrane to convert into corresponding acids and bases. Bipolar membrane dissociation water has no gas or by-products, which will reduce the voltage and maximize the use of energy. In the same bipolar membrane electrodialysis membrane stack, inorganic and organic salts can be converted into corresponding acids and alkalis. Bipolar membrane electrodialysis is mainly used for the regeneration and reuse of acid and alkali in salt preparation; clean production of organic acids and alkalis.
