To develop an inexpensive and simple technology and increase anti-oil fouling resistance for membrane distillation applications, a hydrophilic/oleophobic nanocomposite membrane was fabricated by using SiO2/Chitosan (CT) sol solution coating with different volume ratios (0.5 : 1, 1 : 1 and 2 : 1 v/v) on PVDF membrane surface. The formation of SiO2/CT layer on membrane surface was confirmed by Fourier transform infrared (FTIR) spectroscopy and energy-dispersive X-ray spectroscopy (EDX). The influence of hydrophilic nanocomposite layer on the characteristics of membranes, including in-air water contact angle, morphology, porosity, liquid entry pressure of water (LEPw) and direct contact membrane distillation (DCMD) performance, was investigated. The results show that the composite membrane (SiO2/CT (1 : 1 v/v)- PVDF membrane) by adding of 0.5 and 1 g/L gasoline concentrations not only incurred fouling but also a higher flux with respect to the neat membrane in each gasoline concentration. During 8 hours continuous desalination process of saline gasoline emulsion solution (20 gr/L NaCl solution containing 0.5 gr/L gasoline), it was found that all modified membranes had high performance stability in comparison with the neat membrane, the modified membrane showed high performance stability and flux without decreased salt rejection (99.9%). At the end, we conducted performance comparison between the prepared membranes in current work and presser based process.
