A water treatment plant is processed
at 60000 m3/d. The radial velocity is 1.0 x
10-3 m/sec, the depth of water is 4.0 m, and the maximum
diameter of the tank ⊁ 30 m. Determine the number and dimensions
for the circular sedimentation tanks. Check the retention time,
surface loading rate, and overflow weir. Determine the volume of
sludge per day for each tank if, (SS = 150 mg/L,
removalratio=90%,w.c= 96% and g=1.05 t/m3)
