A wastewater treatment facility needs to install a sedimentation tank as part of their operations. There are two options for the design of the tank, namely a circular tank with a diameter of 5m or a rectangular tank with a square area, with a length of 5m. a) Determine the cost needed for each case given that the water supply is 1,500 m'/d of which 25% is lost to evaporation before entering the tank, and the detention time is 2 hours. Cost vs. height of sedimentation tank 4 3. 20000 40000 60000 80000 100000 120000 140000 160000 Cost (USD) b) Discuss the advantages and/or disadvantages of the different shapes of the sedimentation tanks focusing on construction and maintenance.
