摘要：Response surface methodology was employed to model and optimize the electrodialysis process for Reverse osmosis concentrate (ROC) reclamation in coal-fired power plants. Predictive models were developed for simulation of different input parameters and responses of ED process. The model for responses was statistically verified by analysis of variance which generated a high coefficient of determination value. Moreover, regression analysis showed a good repeatability and agreement of the experimental data to a quadratic model. The optimum operating parameters were found to be 5.9 V of operational voltage, 1.19 m/s of flow rate and 74 min of time. And the corresponding energy consumption and desalination rate were 0.11 Wh/L and 75.3%, respectively.
