By integrating an anion-exchange layer and a cation-exchange layer back-to-back, they act as \"virtual chemical generators\" within electrodialysis stacks.\u003c\/p\u003e\n\u003cp\u003eWhen integrated into a Bipolar Membrane Electrodialysis (BMED) stack, the membrane utilizes the electric field to catalyze the dissociation of water: Protons (H+) migrate toward the cathode side, combining with incoming anions to generate corresponding acids.  Hydroxyl ions (OH-) migrate toward the anode side, combining with incoming cations to generate corresponding bases\/alkalis.\u003c\/p\u003e\n\u003cp\u003eThe main advantages of Neosepta Bipolar Configurations are: (1) \u003cstrong\u003eNo Redox Byproducts\u003c\/strong\u003e: Unlike standard water electrolysis, BMED bypasses gas evolution at intermediate cell boundaries, leading to cleaner operations and significantly lower electrical energy consumption.
