Abstract
In the present study hydrophilic sago/polyvinyl alcohol (PVA) blend membranes were used for pervaporation of ethyl acetate-water mixture. The effects of feed concentration, temperature and permeate pressure on the separation factor and permeation flux were studied by using response surface methodology (RSM). The central composite design (CCD) was used to design the experiment and analyze pervaporation performance of homogenous sago/PVA membranes and also to obtain process optimum conditions. It was observed that the permeation flux and selectivity were changed by feed temperature and concentration more than the permeate pressure. The validity of the model was confirmed by the experiments.
