The ion exchange membrane consists of cation exchange membrane(CEM) ,anion exchange membrane(AEM) and bipolar membrane. The CEM allows the cation only to pass through the membrane while the anion is blocked by the CEM. The AEM works the same way so that the both ions could be separated.
The ion exchange membrane could be mainly utilized in mCDI(membrane capacitive deionization), RED(reverse electrodialysis) , ED(electrodialysis) and BPED(bipolar membrane electrodialysis).
The mCDI is more energy-efficient due to less electric consumption and higher recovery than the reverse osmosis membrane system. Also, easier to reject the hardness which occurs scaling and the fluoride which is relatively hard to reject in the reverse osmosis membrane system. The operation temperature is up to 60 degrees celsius. the 16um membrane is the thinnest, the lowest electric resistant membrane, which is the most energy-efficient and perfect fit for mCDI and RED.
The ED is an application for concentration by recycling. The most common application is wastewater treatment to recycle the specific ions. thick membrane is more efficient to highly concentrate. the 95um membrane is compatible for ED application.
The BPED is high value-added technology especially for lithium production and recycling of lithium battery. Also they produce caustic soda by recycling of sodium sulfate wastewater. The bipolar membrane is the most important material for BPED system due to purity, efficiency and electric consumption.
