Similar to alum, ferric chloride (FeCl3) is commonly used as a coagulant and flocculent in water treatment plants. When FeCl3 is placed in water, it forms Fe(OH)3 solids which helps remove small suspended particles. A 250,000 ppm concentration of FeCl3 is added to the raw water in the rapid mix basin at a flowrate of 5 GPM (gallons per minute). The flowrate of water to be treated is 20 MGD.
Required:
What mass of Fe(OH)3) is generated each day (in kilograms/day)?
