The depletion of freshwater resources and the increasing environmental concerns associated with wastewater discharge have necessitated the development of sustainable water management strategies in various industries, including oil refineries. This paper investigates the potential of ultrafiltration membrane treatment for the reuse of stripped sour water, a challenging wastewater streams generated during the oil refining process. The study aims to assess the effectiveness of ultrafiltration membranes made of polyether sulfone (PES) with Nano zinc oxide and others without in improving the quality of stripped sour water to meet reuse standards within oil refineries. Benefits and challenges associated with ultrafiltration membrane treatment are examined, including the positive impacts on water resource conservation, environmental sustainability, and regulatory compliance. The fundamentals of ultrafiltration are addressed, including the mechanisms responsible and the various membrane configurations used to treat wastewater. Issues of fouling and membrane integrity are as well dealt with and techniques to reduce these problems are mentioned. This study paper contains case studies and research findings from an oil refinery that underwent a pilot for ultrafiltration membrane treatment of stripped sour water. The paper will end with future views and research methodology in order to improve the durability and adequacy of ultrafiltration membrane treatment for stripped sour water and its reuse in oil refineries. This study adds to the growing pool of knowledge on sustainable water management in the oil refining industry. The findings from the study offer useful insights to the operators, researchers and policymakers who are focused on reducing environmental impacts and on achieving effective water resource utilization.
