A settling column analysis is performed on a dilute suspension of particles from water. The suspension exhibited discrete particle settling characteristics. Data collected from samples taken at a depth 1.5 m as follows:
Settling time (min) 0.6 1.2 2.2 4.5 6.0 8.8
Fraction of particles settled 0.30 0.45 0.60 0.70 0.85 0.96
a. Plot the velocity distribution for the suspension
b. Find the overflow rate (Q/A) for a settling tank that will give at least 75 % removal
c. Assuming the feed flow rate is 850 m3//hr., determine the dimension of the settling tank.
d. What is the particle size distribution (mass fraction vs. diameter) if we assume the particle density is that of sand (sg = 2.65)
