What is the settling velocity of a floc of diameter 0.15 mm and density 2.12 g/cm3 in water? 2- Will the floc from problem 4 be completely removed in a typical sedimentation basin if alum was used as the coagulant? Why or why not? Show your work. Hint: Examine peak overflow rates… 3-What would the fractional removal of a 0.01 mm floc of density 2.12 g/cm3 be in:
a) An alum-based treatment process?
b) An iron salt-based process?
c) A lime-based treatment process?
