3. Problem 9.5: The results listed in the table below were obtained during a bench scale experiment with two identical slurry-phase reactors operated in series. Hydraulic residence times given are based on the individual reactors. Slurry solids concentration is 100 g/L and particle density is 2.65 kg/L. Using the data provided estimate the volume required for a full scale system treating 1,000-m3/d if the final soil TOC concentration must be less than 200 mg/kg. Note that the concentrations Ci, C1, and C2 given are for the liquid phase while the concentration CTi includes both the soluble and sorbed TOC. Assume first order rate kinetics based on liquid phase concentrations. What problems might you expect when extrapolating to a field design?
