A municipal wastewater treatment plant discharges a maximum flow rate of (20000 m³/ day), a BOD, @ 20 °C of (50 mg/L), a dissolved oxygen concentration of (3.0 mg/L), and temperature of (24°C). The stream (upstream from the point of wastewater discharge) is found to have a minimum flow rate of (0.75 m³/s), a BODs @ 20 °C of (4.0 mg/L), a dissolved oxygen concentration of (7.5 mg/L), and temperature of (21 °C). Complete mixing of the wastewater and stream is almost instantaneous and the velocity of the mixture is (0.2 m/s).From the flow regime, the reaeration constant rate is estimated to be (0.42 d¹) at (20 °C) and the reaction constant rate is estimated to be (0.22 d¹) at (20 °C). Sketch the dissolved oxygen sag curve a (100-km) (D20,D40,D30 ,D100) reach of the stream below the discharge? Temperature (°C) 21 22 D.O (mg/L) 8.9 8.7 Temperature (°C) 23 24 D.O (mg/L) 8.6 8.4
