Question
Wastewater that has a volumetric flow rate of 0.4 m3 /s and an ultimate BOD of 25.0 mg/L is flowing into a river that has a volumetric flow rate of 4.0 m3 /s and an ultimate BOD of 2.0 mg/L. The dissolved oxygen content for the wastewater and the river is 0.80 mg/L and 8.0 mg/L, respectively. What is the dissolved oxygen concentration just after mixing? If the temperature of the river is 17oC, what is the initial deficit?
