Using the R & T filtration model, plot and compare the concentration profiles of $4$ um Crypto$-$oocysts

through a rapid rate filter $(10$ m$/$h$)$ and a slow sand filter $(0\mathrm{.}10$ m$/$h$).$ Assume $0\mathrm{.}5$ mm diameter sand

media, porosity $=0\mathrm{.}40,$ S$.$G $=2\mathrm{.}65,$ filter depth $=1$ m$,$ and temperature $=20$o C$.$ Assume an attachment

efficiency for the rapid filter of $1\mathrm{.}0$ and $0\mathrm{.}05$ for the slow sand filter. Plot the results as C$/$Co as a

function of filter depth. Explain the differences between the filters in terms filter cleaning methods and

attachment efficiencies. Please show and draw the graphs as well.
