Air stripping prоcess is used аs а pump аnd treat methоd fоr removing a trichloroethylene (TCE) from groundwater. The following conditions apply: Influent flow rate = 80 m3/sec QA/QW = 20 Dimensionless Henry’s constant = 0.2 TCE concentration in the influent = 1.2 mg/L TCE concentration in the effluent = 50 µg/L The amount of pollutant (TCE) in the effluent (liquid stream) is (as Kg/sec):
