100 mL of a solution with a TOC (total organic carbon) concentration of 0.5% is placed in each of the five containers with activated carbon and shaken for 48 hours. The samples are filtered and the concentration of TOC measured, yielding the following analyses: Test beaker no.: 1 2 3 4 5 Carbon (grams): 10 8 6 4 2 TOC (mg/L): 42 53 85 129 267 The Freundlich isotherm is to be used: X/M = k Cf 1/n The value of X/M in the 1st beaker is (mg/g):

Air stripping process is used as a pump and treat method for removing a trichloroethylene (TCE) from groundwater. The following conditions apply: Influent flow rate = 40 m3/sec QA/QW = 20 Dimensionless Henry’s constant = 0.2 TCE concentration in the influent = 1.1 mg/L TCE concentration in the effluent = 50 µg/L The plant operator wants to operate at QA/QW = 2, this operating condition:
