15. Secondary Clarifier Design: Calculate the final clarifier diameter for each of two (2) treatment trains of a system operated in parallel. The total flow will be 10,000 m3/day. mlss = 2200 mg/L, Recycle (R) = 0.27 Use an overflow rate of 20 m3/m2-day and a solids loading rate of 3 kg/m2-day.
Only consider design for the average flow conditions. Make whatever other assumptions are needed. The diameter of each tank in meters will be most nearly :
