MASS TRANSFER IN MULTIPHASE SYSTEMS: VOLATILE ORGANIC COMPOUND
REMOVAL IN THREE-PHASE SYSTEMS
3.2 Derivation of Three-Phase Mass Transfer
There is a need to derive the appropriate relations from air-stripping a VOC adsorbed
onto a solid into the air via a water medium. This process is quite involved as a result of the solid
phase. The process is shown in Figure 9 and simplified in Figure 10.
