Assume that the water temperature is 10°C and the depth of the settling tank is 3.0 m (9.80 ft). Calculate the theoretical settling velocity (cm/s), tank loading (m3/m2/d) and detention time (h) required for the complete removal of the following particles in a settling tank. Assume discrete particle settling A. Sand particles with a relative density of 2.65 and dia. of 0.001 cm to be removed in a presettling tank B. Alum floc with a relative density of 1.002 and dia. of 1.0 mm to be removed in a settling tank after coagulation. C. What will be the corresponding design loading rate and detention time for the above cases if the efficiency of the settling basins is 50%, assuming the removal is linearly related to efficiency?
