What aerobic reactor volume and operating SRT $({}_e)$ are required to treat a $20$ MGD domertic wastewater flow from an inital ultimate BOD$=300m\frac{g}{L}$ to an effluent $BO{D}_y=5m\frac{g}{L}$ assuming a complete mix activated sludge system? Use the design information below assuming $1$st order Kinetics.

$MLVSS=3\mathrm{.}000m\frac{g}{?}=x$

$Y_{\text{m}\text{a}\text{x}}=0\mathrm{.}5$

$K=0\mathrm{.}1$ Lmg'day $(1st$ order degradation rate constant$)$

$K_e=0\mathrm{.}1dr{y}^1$

K $=0\mathrm{.}1$ Lomg'day $(1$st order degradation rate constant$)$
