A wastewater discharge to a plug-flow stream includes some particulate BOD that settles out of the water column in addition to causing deoxygenation. Develop the mass balance equation and solve for the deficit concentration as a function of x, u, Lo, Do, ka, kd,and ks in the stream. Lo ans Do are the initial concentrations of BOD and DO deficit in the stream at x
