Design a fixed-bed adsorption system to treat the contaminant, based on the information given below and the Freundlich isotherm parameters in Table 10-4. Assume the adsorption system removes the contaminant to below the detection limit and the bed density is 450 kg/m3. Your design should include the (a) concentration of the contaminant on the carbon at equilibrium, (b) maximum specific throughput, (c) operating time to reach exhaustion of the media (bed life), (d) volume of water treated in bed volumes, (e) volume of water treated in cubic meters, (f) volume of media, (g) cross-sectional area of bed, and (h) depth of bed.
