The lowest flow in the Ozama River in July is about 48 m3/s. The dissolved oxygen concentration of the river just upstream of the discharge point is 4 mg/l and the ultimate BOD of the river is 10 mg/l. A farm discharges 2m3/s of untreated wastewater with a dissolved oxygen concentration of 0.5 mg/l and an ultimate BOD of 300 mg/l. Both the river and the discharge are at 25°C. what is the initial oxygen deficiency after mixing (i.e., as soon as the wastewater and the river have mixed)? What is the ultimate initial BOD after mixing? Can the farm be allowed to continue discharging raw water? Justify your answer.
