It is the largest waste stream generated in oil and gas industries. The oilfield produced treatment as well as reuse and recycling of produced water to meet environmental regulations. In this work, the wastewater contains contaminants about 250 mg/L has been used as feed. The filtration properties of the membrane were tested by home-made cross flow ultrafiltration using the macroporous composite support with composition 85wt% Al2O3/15 wt%TiO2. The graphene oxide-TiO2 modified thin films have been successfully prepared by sol-gel method and subsequently, heat treated in 400°C. The graphene oxide-TiO2 composite formation can be responsible for enhanced photocatalytic activity under illumination with visible light. During the treatment of oil/water emulsion, the oil removal efficiency higher than 96% was obtained using GO-TiO2 modified membrane via ultrafiltration process. The experimental results indicate that...
