A sedimentation basin in a water treatment plant treats a flow of 6 mgd and has the following dimensions: L = 120’; W = 12’; D = 12’. Water is being treated at an average temperature of 20oC. a. Calculate the water detention time (in hours and minutes), horizontal velocity (in ft/min), and overflow rate (in gpd/ft2, gpm/ft2 and ft3/ft2-day).b. If a particle is to be 100% removed and has a specific gravity of 2.5, what is the corresponding particle diameter (in mm)? Is Stoke’s Law appropriate for this situation? Why or why not?
