Removal of trichloroethylene from water by aeration, pervaporation and membrane distillation

Three processes, aeration, pervaporation and vacuum membrane distillation w ere experimentally and theoretically compared for the removal of dissolved trichloroethylene (TCE) at a concentration of 25 ppm from water. The membra nes used for pervaporation and membrane distillation were a silicone rubber dense membrane and a hydrophobic microporous membrane, respectively. The T CE removal rate was high for the aeration, moderate for the membrane distil lation and low for the pervaporation. The model calculations based on the s ame Henry's constant and vapor-phase driving force model predicted these re sults well.
