A Granulated Activated Carbon (GAC) adsorption laboratory column 10cm in diameter and 3m deep, is found to produce good results in COD removal when operated at a flow of 50L/h. The porosity of the GAC is 0.5 Calculate the following: The application rate in m/h. The residence time, t, in the column. The volumetric flow rate, Vb, in bed volumes per hour, for this residence time. You need to design a GAC system consisting of two columns in series for treating the same water at a rate of 0.5 ML/d. Practical considerations limit the diameter of the columns to 3m. Calculate the minimum required height of the columns.

vated sludge. 12.61 A step-aeration activated-sludge system at a loading of 40 lb of BOD/1000 ft³/day requires an air supply of 1200 ft/lb of BOD applied to maintain an adequate dissolved-oxygen level. The measured average oxygen utilization of the mixed liquor is 36 mg/1/hr. Calculate the oxygen transfer efficiency.
