Transcribed Image Text:

In a wastewater treatment plant, it is required to setup a number of circular sedimentation tanks (in parallel) in the primary stage. The tanks should be suitable to treat wastewater generated from a main city with a population equivalent of 251,500. If the side water depth is 3.0 m, and Qpeak = 4xQavg, === Determine the minimum number of tanks required in the peak condition, given that diameter for each tank = 40 m. (i) (ii) Check the weir loading for each tank at peak flow rates. (iii) Check the hydraulic retention time for the individual tank.
