Published: May 8, 2024

Membrane technology presents an effective solution for treating oily wastewater, a significant environmental hazard stemming from industries such as food processing, metalworking, and oil extraction. Compared to polymeric membranes, ceramic ones exhibit superior mechanical, chemical, thermal stability, enabling more removal easier cleaning. Despite their advantages, membrane fouling remains challenge, impacting the efficiency of wastewater treatment. This review explores characteristics applications in treatment processes. It examines factors influencing fouling, including properties (e.g., concentration, pH), surface hydrophilicity, charge), operational parameters cross-flow velocity, permeate flux). Strategies mitigate pretreatment, backpulsing/backwashing sustained operation, chemical cleaning removal, are discussed. By using can be reduced. Backpulsing/backwashing is maintain long-term operation. Chemical removing irreversible restoring performance membranes. Moreover, modification techniques that enhance highlighted. Ultimately, identifies control crucial optimizing use treatment, underscoring need ongoing research this area.
