Abstract: ABSTRACT The current research aims as introducing polyvinylchloride (PVC) favorable properties such as strength, durability, and low cost to RO membranes through blending it with cellulose acetate (CA). Hence, blend membranes of PVC/CA have been prepared and developed for water desalination. Large-scale membranes (110 cm long × 65 cm wide) were fabricated using a homemade batch casting machine. To save chemicals cost, reduce experimental errors and reduce the number of experiments, a factorial design employing response surface methodology (FDRSM) has been established using experiment design software. Produced PVC/CA membranes were characterized using Scanning electron microscopy (SEM), Thermo gravimetric analysis (TGA) and tensile testing. The performance of prepared PVC/CA membranes has been examined using a homemade lab-scale desalination-testing unit to study salt rejection and water permeate flux. The results established that a PVC/CA blended membrane with 14% PVC and 2% CA, at 30 bars of pressure, achieves salt rejection of 99%, 99.2% and 99.6% from feeds with salt concentrations of 45000, 18000 and 5000 ppm respectively.
