Abstract (EN): Volatile organic compounds are a common source of groundwater contamination that can be easily removed by air stripping in columns with random packing and using a counter-current flow between phases. We propose a new methodology for column design for any type of packing and contaminant: the hydraulic features are previously chosen as a project criterion and only afterwards the mass transfer phenomena are incorporated, in opposition to classical methods. A distributed parameter model for the dynamic simulation of the process is also proposed using a system of two non-linear partial differential equations.
