چكيده لاتين :
An artificial neural network has been used to determine the volume flux and rejections of Ca2 + Na+ and CI-, as a function of transmembrane pressure and concentrations of Ca2 +, polyethyleneimine, and polyacrylic acid in water softening by nanofiltration process יin presence of polyelectrolytes. The feed-forward multi-layer perceptron artificial neural network including an eight-neuron hidden layer has the least error in modeling this non-linear process. The overall agreement between the artificial neural network results and experimental data is very good for both the volume flux and rejections, because the maximum values ofnormalized bias and error are -0.01122 and 1.0737 respectively.
