It is desired to design a sedimentation tank with 1.2m3/m2.h of surface load, 3 hours of detention time, and 5m of water depth parameters according to the water requirement of 220000m3/ day. Considering that ten sedimentation tanks will be built, the tank's length/width ratio is selected as four, and the weir load is 150m3/ day.m, please evaluate the suitability of the horizontal velocity (V0) and the settling velocity (Vs). (The Vs must be greater than the V0. It is predicted that the population will not change for 15 years. The water temperature is 10C with a kinematic viscosity of 1.31106m2/s. The settling velocity of 0.2mm diameter sand: 0.02m/s. The density of sand: 2.65g/cm3, density of water: 1g/cm3, gravitational acceleration: 9.81m/s2 )
