Abstract
A literature review was done in details in desalination by using electrodialysis reversal (EDR). All available data — source of water entered into pretreatment and/or directly into EDR, physicochemical characteristics of water, targeted pollutants, methods and the reasons for the pretreatments, specifications used of EDRs, developments/improvements in EDR, fouling causing compounds and methods to control fouling, membrane types, membrane assembly, spacer, and concentrate management, method, and recovering of ions were searched and summarized in Tables 1–3. From the tables, the concentrations profiles of the targeted pollutants were observed in different sub-processes (i.e., pretreatment, ERD dilute and concentrate streams). The percentage removals of individual ion from different literatures were compared. The concentrations of fouling causing compounds (for examples, CaSO4 and MgSO4) in concentrated streams were eliminated by individual separation process with the specific different types of permselectiv...
