Abstract :
In this study a neural network model is proposed for modeling tri-halo-methane concentration indrinking water. After training, the neural network model predicts tri-halo-methane concentration basedon input data. Parameters such as pH, Temperature, free chlorine residue and TOC were used as inputdata. To validate the proposed method, a case study was carried out, based on the data obtained fromGuilan grand treatment plant (Sangar). The Levenberg-Marquardt algorithm was selected as the bestof thirteen back-propagation algorithms. The optimal neuron number for Levenberg-Marquardtalgorithm is 8 neurons. The performance of modeling was determined. The trends of the forecast andmeasured data were in good agreement.
