7. A contaminated soil is to be excavated and treated in a completely mixed aerated lagoon at a Superfund site. To determine the time that will take to treat the contaminated soil, a lab completely mixed batch reactor is used to gather the following data. Assuming a first-order reaction, estimate the rate constant, k and determine the time (t) to achieve 99% reduction in the original concentration. Time (day) Day 1 Day 16 Note that the 1st order batch system follows, C = Coet Waster Concentration (mg/L) 280 132

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.
