A sludge thickener is used to concentrate waste sludge before sending the thickened sludge to a dewatering process. The thickener receives 800 m3 /day of raw waste sludge at a solid concentration of 20,000 mg/L; after thickening, the solid concentration increases to 5%, which is then dewatered by a filter press that produces a solid cake (biosolids) with a solid concentration of 20% by weight. What is the total weight of biosolids that needs to be hauled away from the plant each day? ( )

Question
A sludge thickener is used to concentrate waste sludge before sending the thickened
sludge to a dewatering process. The thickener receives 800 m3
/day of raw waste sludge
at a solid concentration of 20,000 mg/L; after thickening, the solid concentration increases
to 5%, which is then dewatered by a filter press that produces a solid cake (biosolids) with
a solid concentration of 20% by weight. What is the total weight of biosolids that needs to
be hauled away from the plant each day? ( )
