A large amount of oily wastewaters is generated by industrial sources. Oil-in-water emulsions are the most

serious pollutants for which current treatment technologies are often costly and ineffective. In recent years,

membrane processes have been applied for oily wastewater treatment. Micro

wastewater. A tubular ceramic MF (
