     oily water emulsions are one of the main pollutants emitted into water by industry and domestic sewage. also oily water in inland waterways and coastal zone has become one of the most serious issues of water pollution which needs to be resolved urgently.the results obtained from an experimental study on separation of oil from oily waters are presented. the film tec ft30 membrane was employed and a synthetic emulsion using an iranian crude oil was made. the investigation was focused on the operating parameters that affect the permeate flux and fouling. the following parameters were taken into account: trans membrane pressure, cross flow velocity, temperature, oil concentration and salt concentration.it was found that the flux increases with increasing the trans membrane pressure and also linearly increases with increasing temperature. higher concentrations cause serious fouling on membrane surface, while higher velocities reduce concentration polarization.the oil rejection efficiency decreases when pressure increases but in all cases it was found to be more than 99%. as a result, this membrane can be recommended for treatment of oily wastewater to produce almost pure water.
