“…The increase in energy demand leads to the rise of oil and gas exploration and production generating large volumes of oily wastewater. Various technologies are applied to treat this water, but their effectiveness decreases with decreasing oil content, and the fraction of dissolved oil in water can be retained [ 3 ]. Membrane separation by ultrafiltration is one of the high-performance, selective, and efficient technologies for removing oil from water.…”

“…Thus, water purification and its recovery from pollutions, especially from oils, is an important task that needs to be urgently solved. There are various technologies used for water purification, but they become ineffective at low oil concentrations in water [ 3 ]. The application of membrane technologies (in particular, ultrafiltration) is a relevant alternative due to efficiency, flexibility, productivity, selectivity, and environmental friendliness [ 4 ].…”

Novel High Flux Poly(m-phenylene isophtalamide)/TiO2 Membranes for Ultrafiltration with Enhanced Antifouling Performance

Wide application of ultrafiltration in different industrial fields requires the development of new membranes with tailored properties and good antifouling stability. This study is devoted to the improvement of ultrafiltration properties of poly(m-phenylene isophtalamide) (PA) membranes by modification with titanium oxide (TiO2) particles. The introduction of TiO2 particles improved membrane separation performance and increased antifouling stability and cleaning ability under UV irradiation. The developed membranes were characterized by scanning electron and atomic force microscopy methods, the measurements of water contact angle, and total porosimetry. The transport properties of the PA and PA/TiO2 membranes were tested in ultrafiltration of industrially important feeds: coolant lubricant (cutting fluid) emulsion (5 wt.% in water) and bovine serum albumin (BSA) solution (0.5 wt.%). The PA/TiO2 (0.3 wt.%) membrane was found to possess optimal transport characteristics in ultrafiltration of coolant lubricant emulsion due to the highest pure water and coolant lubricant fluxes (1146 and 32 L/(m2 h), respectively), rejection coefficient (100%), and flux recovery ratio (84%). Furthermore, this membrane featured improved ability of surface contamination degradation after UV irradiation in prolonged ultrafiltration of BSA, demonstrating a high flux recovery ratio (89–94%).

This study evaluated the performance of nanofiltration (NF) membrane for the treatment of hand-drawn batik wastewater containing synthetic dyes as well as real batik wastewater. Three commercial NF membranes (NF270, TS40 and XN45) were used. The effect of transmembrane pressure, NF membrane types, synthetic dyes concentration, and solution types on flux and rejection were investigated. The results showed that the use of all NF membranes could reach dye removal of ca. 99%. NF270 membrane exhibited the highest flux, 2-3 times higher than that of TS40 and XN45 membranes. NF270 membrane was further used for treating real batik wastewater. The results showed high rejections in terms of total suspended solids (TSS), chemical oxygen demand (COD), and total dissolved solids (TDS) were obtained. The practical applicability of NF270 membrane for real handdrawn batik wastewater treatment fulfilled the quality standards in terms of TSS, COD, and BOD parameters. Overall, the NF270 membrane showed favorable performance for batik effluent treatment.

Polymeric Membranes for Oil-Water Separation: A Review

et al. 2022

View full text Add to dashboard Cite

This review is devoted to the application of bulk synthetic polymers such as polysulfone (PSf), polyethersulfone (PES), polyacrylonitrile (PAN), and polyvinylidene fluoride (PVDF) for the separation of oil-water emulsions. Due to the high hydrophobicity of the presented polymers and their tendency to be contaminated with water-oil emulsions, methods for the hydrophilization of membranes based on them were analyzed: the mixing of polymers, the introduction of inorganic additives, and surface modification. In addition, membranes based on natural hydrophilic materials (cellulose and its derivatives) are given as a comparison.
