Determine the effluent concentrations of S$,$ Xa $,$ Xi$,$ Xv$,$ and X $($the total

suspended solids$)$ for a $10$ m$3$ reactor operated as a chemostat that is

fed $3$ m$3/$d of a wastewater containing BOD L of $2,000$ mg$/$l$,20$ mg$/$l

of nonbiodegradable suspended organic solids, and $15$ mg$/$l of inorganic

suspended solids. Assume aerobic conditions exist and that Y $=0\mathrm{.}65$

mg cells$/$mg BOD L$,$ q $=16$ mg BOD Lid per mg cells, K $=25$ mg$/$l$,$

b $=0\mathrm{.}2/$d$,$ and Id $=0\mathrm{.}8.$
