A single-channel tubular ceramic membrane with an average porosity of 0.1μm was used at transmembrane pressures of 1, 2, and 3bars, using the cross-flow filtration principle in a membrane filtration unit. Process efficiency was evaluated in terms of chemical oxygen demand (COD), apparent color, and turbidity removal, along with major requirements such as average permeate flux, percentage of fouling, and contribution of different resistances (resistances in series model) to the total resistance of the membrane. The highest removals for the evaluated parameters occurred in the combined coagulation/flocculation/sedimentation/ultrafiltration process. At a pressure of 2bar, the removal of turbidity and apparent color was 99.9% and that of COD was 98.5%. For the combined process, the lowest percentage of fouling was 59.8%, which occurred at 1bar. The fraction of resistance due to fouling, which may indicate irreversible damage of the membrane, was lower in the process of coagulation/flocculation/sedimentation using M. oleifera as coagulant followed by ultrafiltration than in the process that treated dairy wastewater with direct ultrafiltration for all pressures.
