Abstract: Liquid-liquid extraction was investigated for use with surfactant enhanced subsurface remediation. A surfactant liquid-liquid extraction model (SLLEM) was developed for batch equilibrium conditions based on contaminant ...

Abstract: In laboratory column studies we evaluated chlorinated solvent removal using food grade surfactant-based solubilization and mobilization systems. We used nonionic sorbitan polyethoxylate monostearate for solubilization ...

Abstract: Laboratory studies and model results were utilized to design packed tower and hollow fiber air stripping units which were field tested with a contaminant-laden surfactant stream. Field units were operated at a 1.9 liter/min ...
