Current Patents on the Innovative Applications of Electrodialysis Technology in the Treatment and Reclamation of Industrial Waste Effluent

Author(s): Qing-Chun Ren, Meng Wang, Yu-Xiang Jia, Peng-fei Zhou.


In order to realize the sustainable development of chemical industry, the treatment and reclamation of the industrial waste effluent become more and more urgent. In view of many contaminants in the wastewater produced by the relevant industrial scenario, such as seawater desalination, paper-making industry, leather industry, organic synthesis industry, food processing industry, surface treatment industry, hydrometallurgy, etc., are ionic substances, the versatile electrodialysis technology has found its applications in the treatment and reclamation of industrial wastewaters. In this article, the relevant developments reported recently in the open literatures, especially in the patents, were reviewed and understood from different aspects, such as wide applied fields, multi-level treating results, diversiform treating methods and so on. Furthermore, some potential requirements in this field were also put forward tentatively.

Keywords: Electrodialysis, Ion exchange membrane, Separation, Reclamation of industrial effluent, Treatment of industrial effluent
