| Abstract: | Pervaporation (PV), a membrane separation process, has been used to recover from spent solvent of perchloroethylene
(PERC), one of the solvents used for surface treatment in electroplating industries. Commercial polydimethylsiloxane (PDMS)
flat type membrane (thickness, 200 μm) was employed to remove PERC from spent solvent. A model, based on solutiondiffusion
mechanism, was proposed to predict mass transfer during PV. The effects of permeate pressure and feed flow rate on
PV were investigated to validate the model. A Pervaporation Separation Index (PSI) of 4198.61 was achieved finally. The
moisture content in the final permeate was 1%. |
