Evaluation of Fluoride Concentration in Water Treatment Plants of Baghdad City

Fluoride is one of the elements in water that humans need at a certain rate, but it poses a health hazard if its concentration in drinking water is more than the body requirement. In order to analyze the fluoride concentration in drinking water in Baghdad city and estimate its expected effects on consumers, data were taken monthly throughout three years (2012-2014) for raw and supply water. The results show that the fluoride concentration inTigrisriver was below 1.5 ppm andit was found that AL-Wahda and AL-Rasheed W. T. P. s have the highest percentage of removal for fluoride. Using artificial neural network found that its concentration was affected by temperature, pH, total solids and suspended solid where the pH and suspended solid were the most influential on fluoride.
