Question
What would be the BODs of the wastewater sample, if the initial and after 5 days Dissolved Oxygen (DO) values for the diluted sample are 9.07 and 4.13 mg/L, respectively? BOD, (mg/L) = A/ If the BOD rate constant, k = 0.12 d¹ for problem 1 above, calculate the ultimate BOD. Lt = Lo-e-kt and Lo= Lt + BOD BODult (mg/L) = A/ What is the BOD remaining (remaining oxygen demand) after 5 days. BODRemain (mg/L) = A
