Relatively new Sago/PVA blended membranes were prepared by solution casting technique. Homogenous sago/PVA membranes were prepared with different ratio of sago content in the membrane. The blended membranes were characterized using Fourier Transform Infrared Spectroscopy (FTIR), contact angle measurements, and degree of swelling (DS). The blended membranes were tested for pervaporation of ethyl acetate-water mixture at a range of 1-4wt% of water in the solution. The effects of feed temperature and concentration were investigated. The permeation flux increased around 30% with sago content in the blend membranes from 3wt% to 7wt% at 60oC. However, the separation factor decreased from 433 to 387 for same membrane.
