This study has applied the L16 orthogonal array of the Taguchi method to determine the optimal
combination of three basic controlling material (PVA (poly-vinyl alcohol),Gluteraldehyde,TiO2
nanoparticles) concentration of synthesized PVA/PES composite membrane. PES ultrafiltration
membrane was modified with so-called materials via dip-coating method .Taguchi approach was
employed for ion rejection optimization. The optimum conditions were found as the second level
of PVA, first level of Glu and fourth level of TiO2. surcace analysis of modified and virgin
membranes were conducted with SEM (scanning electron microscopy) and contact angle
measurements.
