ABSTRACT
Air stripping, soil vapor extraction, and air sparging are basic stripping processes that may be used for the successful removal of volatile hazardous waste contaminants from soils and associated groundwater. Such stripping may be conducted in situ or in stripping towers as used in other gas-liquid-system industrial operations. Stripping tower systems may be constructed to provide a mobile technology for hazardous waste site remediation. The gas transfer is based on the gas-liquid equilibrium described by Henry's law. The process is capable of removing volatile organic and gaseous solutes present in low concentrations in the solvent liquid. This chapter describes air stripping, soil vapor extraction, and air sparging in detail.
