Question
Q- Consider a primary sedimentation tank (PST) in a water
treatment plant with Surface Overflow Rate (SOR) of 40 m³/m²/d.
The diameter of the spherical particle which will have 90 percent
theoretical removal efficiency in this tank is
μm. Assume
that settling velocity of the particle in water described by Stokes'
Law.
Given: Density of water = 1000 kg/m³; Density of particle = 2650
kg/m³; g = 9.81 m/s2; Kinematic viscosity of water (v) = 1.10 x 10-6
m²/s
