Determine the dimensions (height, length, and width in ft) of a rectangular sedimentation basin with the following specifications – detention time: 4 hours, overflow rate: 700 gallons per day per ft2, and length:width ratio of 3:1. The sedimentation basin is designed to take in 1.5 MGD.(Show solution)
A water treatment plant is designed to remove 12.0 μm diameter particles with a density of 1.2 g/mL. The water is at 10°C. The plant takes in water at a rate of 0.10 m3/s. The rectangular sedimentation tank has a depth of 4 m and a length:width ratio of 5:1. Calculate the basin’s minimum width (in m) required to remove the particles.(Show solution)
Determine the settling velocity (in m/hr) of a particle with a diameter of 50 μm and density of 1100 kg/m3 in water at 10°C. Note: At 10°C, the density and viscosity of water are 999.7 kg/m3 and 0.001307 kg/m-s.(Show Solution)
