Recovering industrial wastewater: application of electrodialysis reversal approach

Abstract

Water is an important factor for ecosystem balance as well as for the development of any nation. Industrialization and household activities are generating wastewater which causes serious effects to living beings. Industrial wastewater is an important concern, globally. The type of industrial wastewater and wastes present in them depends on the processing of a particular industry. Wastewater treatment is more efficient when chemical, physical, and biological methods are combined. Among all the discussed methods of wastewater treatment in this review, the electrodialysis reversal (EDR) process was found to be more reliable because self-cleaning, decreased membrane fouling, and scaling were introduced in EDR. With such kind of advantages, EDR became popular for wastewater treatment, but furthermore improvement in membrane types and flushing techniques will uplift industrial wastewater treatment processing.
