Progress of Studies on Desalination Performance of Flow-through Capacitor

液流式电容法作为一种新型脱盐水处理技术,基于大比表面积的电极材料,通过外接直流电压的施加,达到去除水中无机盐离子的脱盐目的。详细地从理论角度介绍了液流式电容脱盐技术,概括了炭材料在除盐工艺具有较大优势,并介绍了当前主要的电极成型方法,最后论述了该技术的优势与不足。可以预见,在不久的将来,该项技术一定会得到广泛的应用。

Flow-through capacitor（FTC） has attracted the interest of the community investigating desalination technologies. The technology is based on the recognition that high-specific-surface area electrodes, when electrically charged, can quantitatively adsorb ionic components from water, thereby resulting in desalination. The article reviews the theoretical background of FTC, summarizes carbon materials used in this field, introduces eleclrodc-fabricalion method, and provides a critical review of the advantages and limitations of the technology. It is forecast that FTC will be widely applied in desalination production in the near future.
