Abstract The paper evaluates the influence of selected process variables on the separation of oil from an oil-insaline water emulsion performed using ultrafiltration. The experiments were carried out according to the two-level factorial design with four factors 24 . The following variables were taken into account: flow velocity (4, 5 m/s), transmembrane pressure (TMP) (0.1, 0.2 MPa), salt concentration (1.0%, 3.5%), and oil concentration (500, 1,500 ppm). The separation of the emulsion was characterized using the initial permeation flux J0 , the steady-state permeation flux JSS, and the oil rejection coefficient r. Based on the experimental results, a mathematical description of all the examined variables was proposed in the form of linear and interaction relationships. Such an equation using normalized variables enabled the influence of all process variables on the output quantities, that is, J0 , JSS, and r. It was found that TMP had the greatest impact on the efficiency of the process. The presence of salt caused a slight decrease in J0 and JSS, similar to as the presence of oil
