Question
A plain sedimentation tank with a length of 20 m, width of 10 m and a depth of 3 m is used in water
treatment plant to treat 4 million litre of water per day (4 MLD). The average temperature of water is 20°C.
The dynamic viscosity of water is 1.002 × 10-3 N-s/m? at 20°C. Density of water is 998.2 kg/m3. Average
specific gravity of particles = 2.65. Assume, particles is removed completely.
Surface overflow rate in the sedimentation tank is
Particles of diameter
um are removed completely
