A biological tower with high-density, cross-flow packing has a surface area of 480 ft2 and a depth of 12.0 ft. The packing has a specific surface area of 42 ft2/fl3, n = 0.5, and k20 = 0.0035 (gpm/ft2)0.5. The effluent from the primary clarifier is 600,000 gpd with a total BOD of 126 mg/l and soluble BOD of 62 mg/l. The wastewater temperature is 18°C and the recirculation ratio is 1.0. Calculate the effluent soluble BOD and estimate the effluent total BOD, assuming the ratio of soluble BOD to total BOD is the same as in the primary effluent.
