Abstract
A mathematical model for the removal of volatile organics from water by aeration and by solvent sublation into an organic phase is presented. The model includes the effect of the finite rate of solute mass transfer from the aqueous into the vapor phase. Results are calculated for the removal of 1,1,1-trichloroethane (TCE) chloroform, and benzene from water with 1-octanol, anisole, or kerosene as the organic phase. Experimental data on the aeration of TCE and on its solvent sublation into I-octanol are in good agreement with the model. Small bubbles and long water columns greatly reduce the inefficiency of the process caused by mass transfer rate limitations.This publication has 16 references indexed in Scilit:
