Design and optimization of electrodialysis process parameters for brackish water treatment

Effect of flow velocity and cell-pair thickness in electrodialysis (ED) is studied. The production cost includes pump energy, while the size system considered as an output variable. performance ED depends on three categories process parameters namely water quality data, stack configuration characteristic inside stack. design complex due to interrelation among variables so calculation chronology steps are developed with flow-chart for fix feed salinity groundwater salt removal rate. effect recovery ratio capital energy studied found unidirectional. Sparingly soluble present decides upper limit obtained 70–75% rate based feedwater quality. optimum value linear can be by trade-off cost, pumping cost. Simultaneous both variable minimizing total gives narrow working range 15–17 cm/s 0.4–0.8 mm thickness. minimum 0.08 USD/m 3 at 16 0.5 • Designing pilot scale unit setting parametric chart. Recovery 75% brackish neutral pH level. Product minimization varying simultaneously. Optimum mm.
