would you recommend tor treating sucn emuent?

c$)$ A completely mixed activated sludge process is to be used to treat wastewater flow of $550\frac{m^3}{h}r$

having a soluble $BO{D}_5$ of $250m\frac{g}{m}l.$ The concentration of soluble $BO{D}_5$ escaping treatment is $15$

$m\frac{g}{L}$ Design criteria are as follows: $Y($yield Coefficient $)0\mathrm{.}5,k=\frac{5}{?}$ day, $Kd=\frac{0\mathrm{.}05}{?}$ day, $Ks=100m\frac{g}{L}$

and the concentration of MLVSS $(x)=20000m\frac{g}{L}$

Compute the following:

The treatment efficiency

The mean cell residence time

The volume of the aeration tank

$2+2+4$
