Q10/ A wastewater treatment plant discharges 2.0 m³/s of effluent having an ultimate BOD of 45 mg/L into a stream flowing at 12. m³/s. Just upstream from the discharge point, the stream has an ultimate BOD of 5.0 mg/L. The deoxygenation constant kd is estimated at 0.32 day-¹. Assuming complete and instantaneous mixing, the ultimate BOD of the mixture of waste and river just downstream from the outfall will be:
