Lab Test Equipment Bipolar Electrodialysis Membrane Working Principle and Applications

The lab test equipment equipped with bipolar membranes (EDBM) is capable of producing acid and base solutions from the corresponding saline solution used as a feed by employing the water dissociation function of Bipolar Membranes.


DESALT-EDBM test equipment bipolar membranes  consists of a sequence of three channels hosting the electrolyte solutions separated by three ion-exchange membranes: anion (AEM), cation (CEM), and bipolar (BPM).  The two electrodes and an electrode rinse solution (ERS) are used to convert electricity into ionic current.


In the drawings above, we reported the DESALT-EDBM bipolar membranes working principle.


When an electric potential is applied between the two electrodes, the water dissociation reaction takes place in the interlayer of the bipolar membrane, resulting in the production of protons and hydroxide ions. Due to the applied electric field, the ions are driven to opposite sides of the BPM based on their charge. Consequently, acidic and alkaline solutions are produced.

Bipolar electrodialysis is an innovative and efficient process that capitalizes on the unique properties of bipolar membranes to transform and separate ionic species. 

Some more applications that ca be teste with the lab scale system of bipolar electrodialysis (EDBM) include Lithium Hydroxide production in the lithium industry, NaOH and HCl production from RO brines, CO2 capturing plants, and many more applications.
