We are the hot sales bipolar membrane stack manufacturer in China

Bipolar membrane electrodialysis is a new type of electrodialysis formed by introducing a bipolar membrane on the basis of electrodialysis and combining various configurations of the anion membrane and/or the anode membrane. Unlike the concentrated desalination function of conventional electrodialysis, its function is to convert a salt solution into an acid and a base. Under the action of a reverse DC electric field, the H2O molecules in the catalytic layer are dissociated into H+ and OH- under the action of a catalyst, and migrated through the positive and negative layers to the host solution on both sides of the membrane, respectively. The lowering of the H+ and OH- concentrations causes the hydrolysis to proceed continuously. Simply put, a bipolar membrane is equivalent to a hydrolysis generator that produces H+ and OH-ions.
The bipolar membrane, the combination of the anion membrane and the yang membrane constitute a three-chamber of acid, alkali and salt. The anion of the salt passes through the anion membrane and combines with the H+ ion generated by the bipolar membrane to form an acid. On the other hand, the cation passes through the cation exchange membrane and the double The OH-ion generated by the polar membrane combines to form a base, and the process is equivalent to the reverse reaction process of the neutralization reaction.

Characteristics of Electrodialysis Membrane Stack

  • Energy saving and environmental protection, a new generation of acid-base technology;
  • splitting water into H+ and OH- at low voltage;
  • The acid and alkali are formed from inorganic salts and organic acid salts in a single process, and the process is simple and clean;
  • The concentration of acid and alkali produced is controllable and adjustable;
  • no redox reaction occurs except for the electrodes at both ends, and no by-products are produced;
  • Each chamber does not require electrodes, and the amount of gas generated is small. The investment cost and operating cost account for only 40 to 50% of the electrolysis method.
