Question

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.
