“…Microwave treatment (Sahoo and De, 2010) and heat treatment (Chen and He, 2003) have been occasionally applied to oily water treatment in recent years. But all these methods are very complicated and it takes more time to separate oil from produced water (Karhu et al, 2014;Wei et al, 2013;Sarkar and De, 2011;Sahoo and De, 2010;Chen and He, 2003;Kumar et al, 2015) All these methods are not efficient when the oil concentration is below 400 mg.L -1 and the oil droplet size is less than one micrometer (Padaki et al, 2015).…”

-The present paper deals with the ultrafiltration (UF) of produced water using a polysulfone membrane. Membranes were prepared by the phase inversion technique using polysulfone (PSf) polymer base, poly vinyl pyrrolidone (PVP) additive and N-methyl-2-pyrrolidone (NMP) solvent. Prepared UF membranes were characterized by determining the surface morphology by scannaing electron microscopy (SEM), atomic force microscopy (AFM), porosity, (iii) water contact angle, equilibrium water content and pure water flux, whereas membrane performance was determined by measuring permeate flux and oil rejection using oily synthetic produced water. With the increase in trans-membrane pressure in the cell, the permeate flux increased significantly, but oil rejection showed a decreasing trend. The best UF membrane performance under different trans-membrane pressures was obtained by maintaining ≥90% oil rejection using an UF membrane with the following composition: PSf-15%, PVP -5% and NMP -80%.

“…Being membrane materials, the polymers should demonstrate thermal stability over a wide range of temperature and a chemical stability over a range of pH, and possess a strong mechanical strength. The polymers that are suitable for making membranes include cellulose acetate 3,4 , polyamides 5,6 , polysulfones 7,8 , sulfonated polysulfones 9,10 , etc.. Polysulfones are mainly used to form ultrafiltration, microfiltration and gas separation membranes. They are also used to form the porous support layer of many reverse osmosis, nanofiltration and some gas separation membranes.…”

Polymer solutions of polysulfone (PSf) and methylcellulose (MC) in 1-methyl-2-pyrrolidone (NMP) were used to prepare ultrafiltration membranes by the phase inversion technique via immersion precipitation. The effect of MC additive on the structure and performances of the membranes was studied. The obtained membranes were characterized by scanning electron microscopy (SEM), differential scanning calorimetry (DSC), infrared spectroscopy (FTIR-ATR), equilibrium water content (EWC), water contact angle, porosity and ultrafiltration experiments of polyethylene glycol solutions. It was found that all the PSf/MC membranes had higher porosity, more hydrophilic surface and more vertically finger like pores than PSf membrane. With an increase in MC content in the casting solution from 0.5% to 1.5%, the hydraulic permeability increases from 17.17 to 118.46 L.m -2 .h -1 .bar -1 , while the rejection decreases from 91.82% to 64.45% with PEG 35000. DSC scan and FTIR analysis confirmed that methylcellulose was trapped in the membranes matrix.

“…Kumar et al [7] studied the performance of polysulfone (Psf)–bentonite ultrafiltration membrane and polysulfone–silica membrane for the purification of oil-containing produced water. The membranes were prepared via phase inversion technique by blending silica and bentonite nanoparticles separately with polysulfone and N -methyl-2-pyrrolidone solution.…”

“…The aforementioned problems could have detrimental effects on the quality of MMMs [9], resulting in poor separation performance. Other challenges encountered with the application of MMMs in wastewater treatment are fouling and concentration polarization [9], but surface modification by functionalizing the fillers and surface of the MMMs have been proposed as possible measures to overcome the challenges [5,6,7,8,9]. However, in the case of poor dispersion of the fillers within the polymer materials, especially for carbon nanotube/polysulfone (CNT/Psf) composite membranes, limited reports have been documented in open literature.…”

Effect of the dispersion method employed during the synthesis of carbon nanotube (CNT)/polysulfone-infused composite membranes on the quality and separation performance of the membranes during oil–water mixture separation is demonstrated. Carbon nanotube/polysulfone composite membranes containing 5% CNT and pure polysulfone membrane (with 0% CNT) were synthesized using phase inversion. Three CNT dispersion methods referred to as Method 1 (M1), Method 2 (M2), and Method 3 (M3) were used to disperse the CNTs. Morphology and surface property of the synthesized membranes were checked with scanning electron microscopy (SEM) and Fourier-transform infrared (FTIR) spectroscopy, respectively. Separation performance of the membranes was evaluated by applying the membrane to the separation of oil–water emulsion using a cross-flow filtration setup. The functional groups obtained from the FTIR spectra for the membranes and the CNTs included carboxylic acid groups (O–H) and carbonyl group (C=O) which are responsible for the hydrophilic properties of the membranes. The contact angles for the membranes obtained from Method 1, Method 2, and Method 3 were 76.6° ± 5.0°, 77.9° ± 1.3°, and 77.3° ± 4.5°, respectively, and 88.1° ± 2.1° was obtained for the pure polysulfone membrane. The oil rejection (OR) for the synthesized composite membranes from Method 1, Method 2, and Method 3 were 48.71%, 65.86%, and 99.88%, respectively, indicating that Method 3 resulted in membrane of the best quality and separation performance.
