The development of the membrane process for proteins separation by ultrafiltration (UF) is now get attention especially for commercial industry. Polymeric membrane is a simple and efficient method for designing new materials to improve the performance of the membranes. As continuous developed of new membrane materials, Polyvinylidene fluoride (PVDF) is an important class of polymer that has been widely used in the manufacture of asymmetric polymeric UF membrane. Based on the dry/wet phase inversion technique, the smooth, even and thin asymmetric UF membranes were prepared. The prepared membranes were characterized by Scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FTIR), and Thermal gravimetric analysis (TGA) techniques. The performance of all the membranes prepared have been evaluated in terms of pure water permeation (PWP) at operating pressure from 50 to 300 kPa, permeate flux and Bovine serum albumin (BSA) also Egg albumin (EA) proteins rejection at 100 kPa. Based on the proteins separation performance study, the PVDF/NMP membrane which contains 17 wt% of polymer show the best performance membrane due to its high water productivity (455.82 Lm²h¹) and separation performance (84% BSA, 73% EA) as well as it has good membrane morphological structure. The results revealed that the addition of 3 wt% Polyvinylpyrrolidone (PVP) and Polyethylene glycol (PEG) 200 were formed membrane with higher proteins rejection and thus, the membrane pores were improved. Both of PVP and PEG 200 additives were chosen as the best additive towards the PVP-UF membranes. Besides that, the incorporating of surfactant materials which are Sodium dodecyl sulfate (SDS), Triton X-100 and Tween 80 towards PVP increased the PWP in the range of 577.37-811.92 Lm²h¹ meanwhile towards PEG 200, the PWP increased in the range of 78.97-412.41 Lm²h¹. In term of BSA separation performance, the PVDF/NMP/PVP membrane fabricated with addition of 2 wt% Tween 80 showed highest rejection 0f 90% at low permeate flux (105.51 Lm² h¹). The addition of surfactant towards the PVDF/NMP/PEG 200 membrane were resulted in increase the permeate flux and decreased the proteins rejection. In relations to attain high separation performance, the effect combination of 1 wt% anionic and non-ionic surfactants that are SDS, Tween 80 and Triton X-100 formulations were investigated. Experimental and characterization data on protein separation demonstrated that the SDS/Tween 80 and Triton X-100/ Tween 80 were found to affect the performance, morphologies and membrane pores of AUF-PVDF membrane. Therefore, with the packages of high separation performance and fine structural details, the synthesized AUF-PVDF membrane also provided the excellent technical potentials towards membranes development. |
