A thickener was designed to remove solids from an aqueous suspension. An allowable loading figure of

$32\mathrm{.}5$ m$3/($m$2$ day$)$ was taken from a design handbook and used to size this unit. For adequate performance

this sedimentation unit must treat $5\mathrm{.}68$x$103$ m$3/$day of a suspension having a solids concentration of $2000$
