A sedimentation basin is to be designed with the following characteristics: • Average flow rate = 1.5 MGD • Detention time = 4 hrs • Overflow rate = 700 gpd/ft² - a. If a circular design is used, what are the approximate diameter and depth? - b. If the flow rate is reduced to 0.7 MGD, what are the overflow rate in gpd/ft² and the detention time? - c. According to the design guidelines, the weir loading cannot be greater than 24,000 gpd/ft. Explain how you would install weirs to meet this requirement.

Question: A rectangular primary sedimentation basin is to be designed for an activated sludge treatment plant serving a municipality. The regulatory agency criteria for primary sedimentation basins used for activated sludge system are as follows: peak overflow rate (S) = 80 m3/d-m2, average overflow rate (S) = 40 m3/d-m2, peak solids loading = 50 kg/d-m2, peak weir loading = 372 m3/m-d. The average flow to the basin is 12 000 m3/d. Calculate the tank surface area in m2. Calculate the peak flow rate in m3/d. Calculate the total suspended solids concentration in the incoming flow to the basin (mg/L) Calculate the total weir length (m)

Take note: Answer and write your solution on a clean paper clearly. During a flood flow the depth of water in a 12 m wide rectangular channel was found to be 3.5 m and 3.3 m at two sections 300 m apart. The drop in the water-surface elevation was found to be 0.18 m. Assuming Manning’s coefficient to be 0.023, determine the following: a. Average value of k? b. Estimate the flood discharge through the channel ?
