Modification of Polyethersulfone Membranes to Remove Produced Water Dirt into Clean Water

Produced water contains organic and inorganic contaminants that can pollute the environment The high demand for oil and gas causes continuous exploration. In the process of mining oil and gas large quantities of produced water are produced. Produced water is a by-product of oil and gas processing. Proper processing is needed to make the produced water well utilized. Membrane is an alternative water treatment technology with the principle of filtration. However, in the use of membranes it still has many shortcomings, among others, still the formation of fouling and still not meeting the quality standards of clean water. This is what underlies the research to study the use of materials that can overcome membrane fouling and an efficient system that can make produced water into clean water. In this study, polyether sulfone membrane (PES) with dry / wet phase inversion method and also polyether sulfon nanohybrid (PES) -nano ZnO membrane were made with PES 18 wt% and ZnO 0.5; 1; 1.5% wt. This study also examined the effect of UV light on the membrane for 1.5.10 minutes and the effect of heating at 180oC for 10 seconds. A double stage system is used to improve membrane performance. SEM analysis is used to show that PES membranes have larger pores due to UV irradiation and show a denser membrane pores after heating. Contact angle analysis was also conducted to show that ZnO nanoparticles can improve the hydrophilic properties of membranes. To find out the results of membrane performance, TDS, Cl-, S2and turbidity analyzes were carried out. The four analyzes showed results that significantly declined. With this system, inorganic and organic particles have been held more at the membrane surface. However, in this study, it is still necessary to examine the proper temperature that can improve membrane performance and make comparisons with the performance of membranes that use other nano-particles so that water quality standards can be met.
