Problem $6$: Design a $10m$ deep bio$-$tower to treat domestic ww and seasonal

food process ww with given conditions as follows:

Average flow of domestic $ww=5590\frac{m^3}{d}$

$,$ Industrial $ww$ flow $=4160\frac{m^3}{d}$

BOD$5$ of domestic $ww=240m\frac{g}{L}$

BOD$5$ of domestic $+$ industrial $ww=520m\frac{g}{L}$

Effluent BOD$5=24m\frac{g}{L}$

Value of $k$ at $26C$ at $6m=0\mathrm{.}27\frac{(\frac{L}{s}{)}^{0\mathrm{.}5}}{m}2$

Temperature in summer $=30C$

Temperature in winter $=15C$
