Question
Question #5. The fluoride feeder at the Lemieux Island WTP breaks down. As shown below, the well mixed tank flows into a 5 km long distribution pipe. The volume of the tank is 2.5 m³ and the treatment system serves 190 000 people who each use 200 L/d. The rest of the necessary data is provided in the figure. If the fluoride concentration in the tank is 1.0 mg/L when the feed stops, how long until the concentration of fluoride is reduced to 0.01 mg/L at the end of the distribution pipe? Assume that fluoride acts as a conservative substance. Fluoride C = 1.0 mg/L 5 km u = 0.17 m/s
