In a system with recycle, the following data on inert $($nonbiodegradable inorganics that

originated in the in$$uent$)$ solids concentrations were obtained:

Xin$020$ mg L $1$ Xine $0$ mg L $1$ Xinr $100$ mg L $1$

The system is at steady state and the clari$$er is ideal. What are the values for Qw and

Xin, if Q is $0\mathrm{.}35$ m$3$ s $1$ and the recycle ratio, r$,$ is $($i$)0\mathrm{.}5($ii$)1\mathrm{.}0?$ Does the $$ow regime $($i$.$e$.,$

CM or PF$)$ in the reactor make any difference? If it does, perform the calculations for

each regime.
