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 ?
Since there is a need to supply more water from reservoir A to reservoir B, it is necessary to lay an additional pipe parallel to it. The existing pipe is 0.6m in diameter with a discharge of 0.5m³/sec between the two reservoirs and 6000m long. Assume f = 0.02 %3| for the old pipe and f = 0.25 for the additional pipe. Determine the following: %3D a. If the additional pipe will have a discharge of 0.65m³/sec of the same length and the head difference between the two reservoirs is constant, find the pipe diameter. ANSWER: h= 25m Existing Pipe Q=0.50m³/sec D = 0.697 m в Additional Pipe b. If the additional pipe of 0.6m in diameter is laid out from the original pipe at its midpoint towards reservoir B, find its capacity. Assume f = 0.02. Also solve for the change in the %3D flow or discharge from A to B. ANSWER: Existing Pipe h=25m QA = 0.7232m/s, QB = 0.3923m³/s, %3D AQ = QA – Q = 0.5271m³/s %3D | в `Additional Pipe
