Abstract
This study investigated the physicochemical characteristics and treatment methods for finely dispersed oil-containing wastewater with a dispersed phase particle size of less than 100 nm. For this purpose, both novel composite membranes developed by the authors and commercially available analogs were used. The novelty of the work lies in the development of a method for producing composite membranes comprising a micro-mesh support and a surface layer of cellulose acetate. The developed ultrafiltration membranes consisted of a micro-mesh coated with a layer of cellulose acetate. Nylon was chosen as the base material for the micro-mesh due to its strength and chemical resistance. The pore size of the developed ultrafiltration membranes ranged from 0.05 to 0.1 μm, which allowed for effective separation of oil particles sized 82–86 nm present in the emulsions. Compared to the commercial UPM-100 membrane, the developed membranes demonstrated higher performance and fouling resistance.
期刊介绍：
The journal Membranes and Membrane Technologies publishes original research articles and reviews devoted to scientific research and technological advancements in the field of membranes and membrane technologies, including the following main topics:novel membrane materials and creation of highly efficient polymeric and inorganic membranes;hybrid membranes, nanocomposites, and nanostructured membranes;aqueous and nonaqueous filtration processes (micro-, ultra-, and nanofiltration; reverse osmosis);gas separation;electromembrane processes and fuel cells;membrane pervaporation and membrane distillation;membrane catalysis and membrane reactors;water desalination and wastewater treatment;hybrid membrane processes;membrane sensors;membrane extraction and membrane emulsification;mathematical simulation of porous structures and membrane separation processes;membrane characterization;membrane technologies in industry (energy, mineral extraction, pharmaceutics and medicine, chemistry and petroleum chemistry, food industry, and others);membranes and protection of environment (“green chemistry”).The journal has been published in Russian already for several years, English translations of the content used to be integrated in the journal Petroleum Chemistry. This journal is a split off with additional topics.
