Oily water emulsions are the main pollutants emitted into water by industry and
domestic sewage and are the major pollution problem because oilfield produced
water has distinctive characteristics due to organic and inorganic matter. Mainly,
it includes salt and hydrocarbons, which may be toxic to the environment. So far,
there are several techniques for oil separation. Typical ones include chemical
emulsification, pH adjustment, gravity settling, centrifugal settling, filter coalescence,
heating treatment, electrostatic coalescence, membrane separation, etc.
There are some advantages and disadvantages connected with each of these
techniques. This paper reports the application of UF membranes for hydrocarbon
wastewater separation. The aim of this study is to investigate the effect of
membrane properties and the effect of operating conditions, i.e., the transmembrane pressure and the initial feed concentration on ultrafiltration of the
synthesized oily water.
