Sodium fluoride has a solubility of 4 percent over the temperature range com- monly encountered in water treatment. A water containing 0.3 mg/L F is to have its concentration increased to 1.2 mg/L F. For a flow of 10,000 m³/day, determine the weight of sodium fluoride used per day. If the chemical is fed as a 4 percent solution, what is the appropriate flow rate?
