A tannery wastewater flow of 0.011 m3 /s and a BOD5 of 590 mg/L discharges into river. The creek has a flow rate of 1.7 m3 /s. Upstreatm of the tannery wastewater discharge point, the BOD5 of the creek is 0.6 mg/L. The BOD rate constants (k) are 0.115 day-1 for the tannery waste and 3.7 day-1 for the creek. (a) Calculate the initial ultimate BOD after mixing.
