Artificial neural network modeling and response surface methodology of desalination by reverse osmosis

▶ The highest factors interaction effects exists between the pressure and salt concentration. ▶ The feed flow rate has the smallest non-linear effect on the RO performance index. ▶ The effect of pressure is more significant at higher feed temperatures. ▶ The effect of the feed temperature is higher at higher operating pressures. ▶ The optimal conditions offered by ANN are better than those given by RSM.
