Steam stripping for removal of organic pollutants from water. 1. Stripping effectiveness and stripper design

This study, presented in two articles, investigates the potential of steam stripping as a general at-source treatment of process water and wastewater for removing organic pollutants. Part 1 here presents stripping-factor-type equations for a primary design of strippers and a practical guideline for a quick evaluation of stripping effectiveness. These handy tools are supported by an experimental study of steam stripping for removing nitrobenzene from water. The simple guideline also reveals that steam stripping is in general more effective than common air stripping (or by other inert gases) at ambient temperature and pressure
