| Popis: | Electrodialysis/electrodialysis reversal (ED/EDR) is a promising brackish water desalination processes. As with any other desalination process, ED/EDR can be affected by several operating and design factors, many of which have been investigated thoroughly. The influences of operating factors—such as applied voltage, flowrate, and temperature—are known, as are the influences of several design factors, such as membrane characteristics, spacer configuration, and spacer thickness. However, no published results have explored how electrode design affects the process. This paper uses pilot-scale experiments at the Brackish Groundwater National Desalination Research Facility to investigate how three different electrode designs—full, recessed, and tapered—affect the performance of EDR systems. Performance was measured as the amount of electrical current in the stack, removal percentage, and standardized power consumption (SPC); the key factor for the comparison was considered to be SPC. The experiments wer... |
