Improvement of PES Nanocomposit Membrane Performance Through UV and ZNO Concentration for Refinery Waste Water Purification

Abstract

Wastewater is generated from the process of purifying large amounts of water. Refinery wastewater can be purified with PES-ZnO nanocomposite membrane technology. Membrane modification to reduce membrane fouling. Therefore, it is important to provide a low-fouling (non-fouling) membrane. However, currently the formation of fouling and clean water quality standards has not been met. Therefore, researchers studied the use of materials that can overcome membrane impurities and an efficient clean water production system. In addition, one alternative to improve membrane performance is to use nanocomposites (ZnO). The membrane was made with a concentration of PES 18 wt% and ZnO 0.5; 1; 1.5% by weight. with the influence of UV light on the membrane for 1,5,10 minutes at a temperature of 180°C. SEM analysis was used to show that the PES membrane has larger pores. Angle contact analysis was also carried out to show ZnO nanoparticles can improve the hydrophilic properties of membranes. For this reason, a TDS analysis is carried out, namely Cl−, S2 − and turbidity. From this analysis shows significant results with membrane performance, modification with UV radiation and the addition of PVA / PEG have interrelated effects to improve membrane performance.
