“…The physical bulk modification involves the formation of membranes for the separation of water-oil emulsions using mixtures of synthetic hydrophobic polymers (for example, polysulfone (PSf)) and hydrophilizing additives (for example, acetates [ 53 ], polyethylene glycol [ 54 ], polyvinylpyrrolidone [ 55 ] or particles of inorganic substances [ 56 , 57 ]). It should be noted that these techniques equally apply to both flat and hollow fiber membranes.…”

“…Polysulfone does not have highly reactive functional groups; therefore, the main approaches to the hydrophilization of PSf are the addition of hydrophilic water-soluble polymers [ 47 , 76 ] or inorganic particles—for example, bentonite [ 70 ], silicon oxide [ 57 ], or candle soot [ 72 ]—to the casting solution. In addition, Table 3 shows that PSF-based membranes are modified by applying thin selective layers of other polymers—for example, dopamine [ 74 ] or cross-linked polyethylene glycol diacrylate [ 75 ].…”

Polymeric Membranes for Oil-Water Separation: A Review

et al. 2022

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.

“…[66] Figure 1A shows an example of a pilotplant scale unit in combination with the conventional ones as coagulation, aerobic biological treatment, air floatation, [67] and sand filter before UF module in a system for the treatment of OWW for water reuse. In other cases, the UF module can be used as a pre-treatment unit for oil wastewater before using NF [68] also, followed by a RO system to reach high efficiency for treatment allow water safe disposal [69] to apply in other applications as in drinking and crops watering. [23] Several membrane companies are offering combined systems for treatment with membranes to treat oil-water emulsions.…”

found with other insoluble matter, presenting relevant problems with safe and convenient separation. The legal discharge of oil-water emulsions is a complex process. [4] Thus, environmental authorities have established stringent regulations to cope with it. [5] Depending on countries, the oil limits are concentrations below 40 ppm as in Vietnam, [6] and in other countries like Korea, the maximum is only five ppm of oil in discharge. [7] Generally, the oil phase in water has three forms, based on oil droplets, size of more than 150 micrometers is called free oil, but that size found from 50 to 150 micrometers is the dispersed oil, [8] finally, the emulsified oil less than 20 µm. There is an increasing interest in employing membrane technology for filtering smaller size oil droplets. In this review, oil-water emulsion problems are highlighted with oil-water separation techniques selection and their performance with varied oil concentration and composition of other immiscible or miscible components. [9] Membrane technology is known formerly to economically advantageous for oily wastewater (OWW) treatment compared with other conventional technologies. [9] Based on the literature, the membranebased treatment cost estimation was about 1 and 3 $ m −3 , [10] lower than for dissolved air floatation (DAF) treatment (cost was 3.65 $ m −3 ). Generally, the treatment cost depends on OWW sources, as each industry has its specific blends for oil and grease jointly with other membrane foulants. [11] For example, oil-water emulsions treatment from the fatty acid industry has a total capital cost (costs of membranes, electricity, labor, cleaning, and maintenance) of 2.65 $ m −3 , compared with the railroad industry (it was ranged from 1.03 to 1.48 $ m −3 ). These costs for the metalworking OWW using UF were 2.8 $ m −3 . In microfiltration (MF) membrane, the OWW membrane-based treatment for oil concentration of 50 ppm annual cost was estimated as 0.098 $ m −3 with a feed rate of 100 m 3 day −1 . [9] The cost of membrane-based treatment of OWW is generally varying but is lower than conventional technologies. [12] 1.1. Oil-Water Emulsions Sources, Environmental Hazard, and Discharge Limits An oil-water emulsion is either a waste stream product, or secondary product. These effluents are generated from different areas and industrial sectors like the petroleum& gas sector, food processing, shipping facilities and maritime, and many others Oily wastewater is generated by various industries in extraordinary growing volumes, such as oil refineries, petrochemicals, metallurgical, food & beverages, and dairy industries, which need oil removal for safe discharge to the environment. Lower cost of production with high oil removal and efficient performance compared to classical methods for treating oil-water emulsions attributed to the alleviation of operation. That emphasizes membrane modification to enhance wettability, hydrophilicity with the antifouling property such as membranes dealing with tiny oil emulsions to be the key parameters to im...

“…PA6 is a semicrystalline polymer with good chemical resistance in organic media, low melt viscosity, a high crystalline melting temperature, high tensile properties, and good impact strength when not notched, making it very attractive for engineering applications [ 9 , 10 ]. Common applications of PA6 are gears, seals, automotive parts, electrical components (circuit breakers, switches, and connectors), membranes, and biomaterials [ 11 , 12 , 13 ]. However, PA6 has some drawbacks, including high moisture absorption, dimensional instability, and fragile behavior when notched, creating restrictions on use in some applications [ 14 , 15 , 16 ].…”

In this work, polyamide 6 (PA6) properties were tailored and improved using a maleic anhydride-grafted acrylonitrile-butadiene-styrene terpolymer (ABS-MA). The PA6/ABS-MA blends were prepared using a co-rotational twin-screw extruder. Subsequently, the extruded pellets were injection-molded. Blends were characterized by torque rheometry, the Molau test, Fourier transform infrared spectroscopy (FTIR), impact strength, tensile strength, Heat Deflection Temperature (HDT), Differential Scanning Calorimetry (DSC), Thermogravimetry (TG), Contact Angle, Scanning Electron Microscopy (SEM), and water absorption experiments. The most significant balance of properties, within the analyzed content range (5, 7.5, and 10 wt.%), was obtained for the PA6/ABS-MA (10%) blend, indicating that even low concentrations of ABS-MA can improve the properties of PA6. Significant increases in impact strength and elongation at break have been achieved compared with PA6. The elastic modulus, tensile strength, HDT, and thermal stability properties of the PA6/ABS-MA blends remained at high levels, indicating that maleic anhydride interacted with amine end-groups of PA6. Torque rheometry, the Molau test, and SEM analysis suggested interactions in the PA6/ABS-MA system, confirming the high properties obtained. Additionally, there was a decrease in water absorption and the diffusion coefficient of the PA6/ABS-MA blends, corroborating the contact angle analysis.
