【 摘 要 】

References(8)Cited-By(7)Three processes, aeration, pervaporation and vacuum membrane distillation were experimentally and theoretically compared for the removal of dissolved trichloroethylene (TCE) at a concentration of 25 ppm from water. The membranes used for pervaporation and membrane distillation were a silicone rubber dense membrane and a hydrophobic microporous membrane, respectively. The TCE removal rate was high for the aeration, moderate for the membrane distillation and low for the pervaporation. The model calculations based on the same Henry's constant and vapor-phase driving force model predicted these results well.
