WebFirst substitute the BOD decay equation for L. This arrangement matches the standard form: So, use the integrating factor: Separate variables and integrate. Apply the boundary condition that at t = 0, D = D 0. Finally, after grouping like terms, the integrated equation is: where . L0 = ultimate BOD in the water at t = 0. D0 = deficit at t = 0. WebA mixture of river water and effluent from a municipal wastewater treatment plant is completely mixed near the point of discharge. The dissolved oxygen concentration in the river at the mixing point is 5.6 mg/L, and the ultimate BOD of the mixed water is 24 mg/L. The temperature of the river is 21°C.
