Monitoring and Modeling of Fayoum Distribution Networks According to Trihalomethanes Formation

Abstract

This paper  aimed to predict THMs con. in water networks having multiple feeding sources.  Results showed that the THMs con. in all the selected points in the distribution network of Fayoum, Egypt was less than the maximum  acceptable con. A statistically-based empirical models were developed for predicting THMs formation under different condition. The first model was developed to predict THMs con. at the exit of the conventional WTPs with R² = 0.83. The second model was developed to predict THMs con. at the exit of the Direct filtration WTPs with R²= 0.842. The third model was developed to predict THMs con. for water supply networks having one feeding source with R² = 0.856. The fourth model was developed to predict THMs con. for water supply networks having multi-feeding sources with R² = 0.555. Furthermore, WaterCad program was used to predict THMs con. at FWSN with 1.55 day^-1 THMs growth rate.
