Question 1: You have been assigned to design primary clarifiers for a wastewater treatment plant. The average flow rate of the wastewater is 256000 m3/day with a BOD5 of 120 mg/L and suspended solids concentration of 300 mg/L. The goal is to remove 35% BOD5 and 60% suspended solids in primary treatment. Determine the following: 1) The diameter of the primary clarifier for a surface overflow rate of 50 m3/m2-day.2) The detention time in the primary clarifier and the mass of solids removed in kg/day.Assume a depth of 4m.
