A rectangular sedimentation tank following coagulation flocculation is to treat a flow of 3000 m3 / day with a detention time of 6 hours. It is to be hand cleaned of sludge at 6 week intervals. The suspended solids concentration of the water is reduced from 250 mg/L to 5 mg/L by coagulation flocculation. The settled sludge includes 40 mg/L (based on water flow) of metallic precipitate and has a moisture content of 85% and specific gravity of 1.24. Determine the volume of sludge produced between cleanings and the basic dimensions of the tank if the water depth just before cleaning is 3 m and its length is twice its width.

Question
Transcribed Image Text:A rectangular sedimentation tank following
coagulation flocculation is to treat a flow of
3000 m3 / day with a detention time of 6
hours. It is to be hand cleaned of sludge at 6
week intervals. The suspended solids
concentration of the water is reduced from
250 mg/L to 5 mg/L by coagulation
flocculation. The settled sludge includes 40
mg/L (based on water flow) of metallic
precipitate and has a moisture content of
85% and specific gravity of 1.24. Determine
the volume of sludge produced between
cleanings and the basic dimensions of the
tank if the water depth just before cleaning
is 3 m and its length is twice its width.
