Problem $12$: A treatmont plant processes $10$ MGD of wastewater with $240m\frac{g}{L}OD$ and $225m\frac{g}{L}$ suspended solid $($SS$).$ The discharge from the final ciarifier contains $15mg$ L BOD and $20$ mg$/$L SS$.$ Primary clarifier removes $60\%$ of the suspended solids and $35\%$ BOD. Howewer, BOD reduction does not contribute to the primary sludge production. The primary sludge has a sp gravity of $1\mathrm{.}02$ and solids content $6\%.$ The cell yield $($conversion of BOD reduction to biological solids$)$ is $65\%.$ Calculate the volume of sold $(f{t}^3)$ from primary sludge.
