Sulfate regeneration method |
| abstract |
(57) [Abstract] [Purpose] In the pulp manufacturing process, the amount of salt dumped in the open sea is reduced by reusing sodium sulfate discharged as a by-product from the chlorine dioxide generation process. [Structure] Sulfate recovered after chlorine dioxide is generated from an aqueous solution containing chlorate is supplied to a two-chamber electrodialysis device composed of a bipolar membrane and a cation exchange membrane, The sulfate is decomposed into sulfuric acid and alkali, and the generated sulfuric acid is reused to generate chlorine dioxide. |
