Removal of micropollutants in aqueous streams by organophilic pervaporation

摘要

In this work a laboratory pervaporation equipment using three different flat organophilic membranes: PERVAP1060 (Sulzer), POMS and PEBA (GKSS), for pure compounds (TCE, Ethylbenzene and MTBE) has been assembled to prove micropollutant separation. Previous membrane adsorption tests have been performed to pre-screen the most suitable membranes for each compound. The different parameters of the process, that is, membrane material, membrane thickness, water flowrate, solution temperature, initial feed concentration, operation time and vacuum pressure have been evaluated for the MTBE.
