Design a sedimentation basin with the following specifications assuming a flow of 1.5 MGD: • Rectangular basin • Depth: 7-15 ft • Width: 15-50 ft • Length: 4 to 5 times the width • Influent and effluent baffles to reduce flow momentum • Detention time: 5-8 hours • Flow through velocity: <0.55 ft/min • Overflow rate: 500-1,000 gal/day-ft2 Draw a figure to show calculated dimensions. You may consider to use SI units in calculations. Hint: Overflow rate is Flow/Surface Area; Detention time is Volume of tank/Flow rate; and Depth= Volume/Surface area
