Abstract

Haloacetic acids are disinfection by-products formed during oxidation of natural water. In this study, linear and nonlinear models were developed based on field-scale investigations. These statistical models were applied to predict the formation of haloacetic acids in the treated water. Pearson’s correlation was used to check significance of raw water determinants at the probability of 0.05. Multiple forward stepwise regression method was used to develop these models which were then validated using another set of results from the identical source. These predicted results show that linear model was better fit than nonlinear model. A plot of predicted and measured values showed that the Pearson’s coefficient and the slope were in good agreement. The developed models can thus be used to reduce the occurrence of haloacetic acids in treated water by means of regulating the raw water quality used for the treatment plant.
