Bipolar membrane is a kind of ion exchange membrane with special functions. Hydrolysis happens and produces H⁺ and OH^– in the middle region of the membrane under the influence of external electric field. Bipolar membrane electrodialysis technology makes this particular function in composite to ordinary electrodialysis to realize the production and regeneration of acid/alkali. The application of bipolar membrane electrodialysis technology can not only achieve the conversion of organic acid salt or organic alkali salt, but also produce NaOH or HCl, which can be used in the production process. The bipolar membrane electrodialysis will play an increasingly important role in clean production and resource recycling.

Application:

· Organic salts produce organic acid base / inorganic salts to produce inorganic acids and bases

· Ferrate preparation

· Chemical synthesis in organic phase

· Treatment of uranium processing wastewater

· Regeneration of sodium sulfate in the production of rayon

· Gas absorption

· Extraction and transformation of organic acids in fermentation broth

· Precipitation separation of soybean protein isolate

· Production of caseinate

· Juice stabilization
