Abstract	Researchers prepare a novel hollow fiber membrane for the treatment of industrial wastewater in Al-Daura refinery in Baghdad using the submerged membrane bioreactor (MBR) technique with a new membrane-type module. The hollow fiber characterization appears to be within the range of ultrafiltration membranes. The fabricated hollow fibers have a skinless porous outer surface. The effects of mixed liquor suspended solids (MLSS) concentration and preheating temperatures of the effluent wastewater at various preheating periods on the performance of MBR and removal efficiency of COD, BOD, oil content, phenol, and turbidity were studied. They observed that the removal efficiency of COD, BOD, oil content, phenol, and turbidity were enhanced by increasing of MLSS concentration. The obtained results confirmed that the initial wastewater preheating followed by the submerged MBR can be offered as a possibility of alternative process for oily wastewater treatment, especially when reuse of oily wastewater is taken into account.
