ENV 6015 Adsorption Solution to Problem Set 1. An industrial waste has an average total organic carbon concentration of 100 mg/l and an average flow rate of 50 l/s. The pH of the wastewater is 4.4 and therefore no adjustment is necessary for activated-carbon adsorption. Three carbons have been studied. The results of batch-equilibrium experiments are presented in Table 1 and the results of rate studies are presented in Table 2. Find a) Eq. Coefficient; b) Mass-trans Coefficient; c) Fractional Capacity; d) time for Breakthrough (assuming 0 mg/L as breakthrough) in a 10 m column with liquid flux of 1 Kg/m 2 -s and a dry carbon density of 300 Kg/m 3 .
