| Abstract: | The brine preparation system for ion-exchange membrane electrolyzers was checked when the electrolyzers were transformed into the type of membrane-thickness electrode-distance. Various factors causing fluctuation of brine quality were analyzed, including the quality of primary brine and secondary brine, such as excess amount of base, pH value, such ion content as barium, iron, silicon, aluminum, manganese, calcium, magnesium, and strontium, and content of sodium chloride ; and the ion content in raw salt, industrial water, deionized water, ion-exchange membrane regeneration water, desulphated di- lute brine, and high purity hydrochloric acid, such as barium, iron, silicon, aluminum, manganese, improvement measures were proposed |

| Keywords: | brine refining ion-exchange membrane caustic soda brine quality check membrane-thickness electrode-distance transform |
