| Abstract: | Air sparging is an important remediation technique for removing volatile organic contaminants (VOCs) from saturated soil and groundwater. Three approaches are employed in the existing models to predict the fates of VOCs in the gas and liquid phases during air sparging of groundwater in the saturate zone. The paper presents the fundamentals, assumptions and relevant equations of the lump-parameter, multiphase fluid flow and TOUGH2 models, major model parameters, affecting factors, development and application prospects. |
