Bipolar Chamber and Electrochemical Liquid Treatment Apparatus Having Such Bipolar Chamber

摘要

A bipolar chamber is used in an electrochemical liquid treatment apparatus such as an electrodialyzer and an electrolyzer. The bipolar chamber includes an anion-exchange membrane ( 1 ), an electrode ( 2 ), and a cation-exchange membrane ( 3 ). A liquid is supplied between the cation-exchange membrane ( 3 ) and the anion-exchange membrane ( 1 ). The anion-exchange membrane ( 1 ), the electrode ( 2 ), and the cation-exchange membrane ( 3 ) are arranged in this order from an anode side of the bipolar chamber. The liquid may include pure water or a nonelectrolyte aqueous solution.
