Literature sources regarding membrane purification of emulsified wastewaters containing hydrocarbons have been reviewed. A traditional means of preliminary purification of the disperse phase in order to reduce clogging of membranes has been presented. As an alternative promising option, the possibility has been considered of modification of membranes by chemical reagents in order to give them hydrophobic, amphiphilic, and hydrophilic properties for separation of direct and reverse emulsions. The main patterns of change in membrane properties and characteristics were considered, including changing of moistening, chemical composition, porosity, and roughness, which promote an increase in the performance and selectivity of the process under consideration. A method to recuperate the concentrate of membrane separation of emulsion as an inhibitor of corrosion has been proposed. The issues of membrane regeneration have been briefly covered.
