A municipal wastewater treatment plant employs three circular primary clarifiers arranged in parallel, following the bar screen and grit removal chamber. The plant receives 12 MGD. Each clarifier is center-fed (water enters at the center and exists at the perimeter).The clarifier radius is 56 ft and depth is 10 ft.What is the hydraulic loading rate (critical velocity) in each clarifier in units of ft3.ft-2.hr-1 ?
