A municipal wastewater treatment plant with average flow of 1.5 MGD and maximum flow during the day is 2.6 times the average hourly flow has decided to design a circular sedimentation basin. The overflow rate based on the average daily flow is 800 GPD/ft? and the same based on the peak hourly flow is 1800 GPD/ft?. The minimum depth of the basin would be 10 ft. For the proposed basin (a) determine the diameter (b) the design diameter of the tank if sludge rake equipment is available in 5-ft increments in diameter.

A municipal wastewater treatment plant with average flow of 1.5 MGD and maximum flow during
the day is 2.6 times the average hourly flow has decided to design a circular sedimentation basin.
The overflow rate based on the average daily flow is 800 GPD/ft? and the same based on the peak
hourly flow is 1800 GPD/ft?. The minimum depth of the basin would be 10 ft. For the proposed basin
(a) determine the diameter (b) the design diameter of the tank if sludge rake equipment is available
in 5-ft increments in diameter.
