Abstract

This article is devoted to the analysis and selection of a method for wastewater treatment containing petroleum products. The advantages of baromembrane separation are given, as well as the rationale for choosing the ultrafiltration method as the most promising membrane method for wastewater treatment of transport enterprises. Ultrafiltration membranes have a wide range of applications in various industries. They are successfully used in the wastewater treatment processes of oil refineries and transport enterprises from emulsified petroleum products, in industrial wastewater reuse systems. For the purification of oily wastewater from transport enterprises, a design of a flat-chamber multi-section apparatus of the "filter press" type is proposed, which most fully meets the requirements for the purification of oily wastewater.
