Wastewater Engineering Dr. Ali Jalil Chabuk Second Course - Lecture 4 Homework: Q1. Design rectangular settling tanks for the following conditions: 1- Served population = 2000000 person 2- Provide four rectangular basins: 3- Select surface overflow rate at average design flow = 40 m/m2. d (Table 9.1) %3D 4- Average design flow rate = 80000 m/s 5- Side water depth = 3.5m The design should be satisfying all design criteria. Q2. Two rectangular settling tanks are each 6 m wide (W), 24 m long (L), and 2.1 m deep (h). Each is used alternately to treat 1900 m' in a 12 h period. Compute the surface overflow (settling) rate, detention time, horizontal velocity, and outlet weir loading rate using a V-shaped weir with three times the width. Q3. A city must treat about 20000 m/d of wastewater with an overflow rate of 40 m/d. two circular basins use to produce satisfactory removal at a depth of 3.5 m. Determine the diameter required for settling basins, detention time, Surface overflow rate, and horizontal velocity.
