“…Indeed, the worldwide water contamination with numerous industrial, agricultural, and natural chemical compounds has recently increased rapidly, which is one of the key environmental issues . In this regard, membrane processes have gained a great interest as a result of their advantages including easy and well‐arranged process conduction, selective separation, automatic and continuous operation, purification without the need for addition of chemicals, low‐space requirement, and easy scale‐up …”

In the present research, the low water flux of polyphenylsulfone membranes was addressed, and a novel improvement in their water permeation and fouling resistance was achieved using polyethylene glycol (PEG) as the hydrophilic additive. Scanning electron microscopy and field emission scanning electron microscopy, atomic force microscopy, attenuated total reflection Fourier‐transform infrared spectroscopy, thermogravimetric analysis, and tensile test were applied for the investigation of membrane morphology, surface topography, surface chemical structure, thermal stability, and mechanical properties, respectively. Moreover, the relative hydrophilicity/hydrophobicity of the membranes was assessed via determination of membrane water uptake capacity and water contact angle. The membrane performance was studied and compared by determination of pure water flux and filtration of canned beans production wastewater as well as bovine serum albumin solution. The filtration results indicated a remarkable pure water flux and 100% turbidity rejection provided by the polyphenylsulfone/PEG 20 000 membrane. In addition, it was confirmed that the amount of residual PEG within the membrane was increased with increasing PEG molecular weight and concentration.

“…Furthermore, the surface of the CA membrane [Figure (c)] after preconditioning in MTBE has been cracked and fragmented. In fact, membrane fragmentation occurs more intensively by microcrack creation, increase in effective surface area of the membrane, and roughness enhancement, which stems from air molecules trapped in surface cavities …”

“…For the PAN sublayer, less compaction and decreased crosslink density compared to the initial structure of the membrane before preconditioning may cause the contact angle decrease in the membrane in MTBE solvent. Also, it is believed that the presence of hydrophilic groups and connection between the solvent and polymer active groups, due to high affinity and proximity of Hansen solubility parameter between them, are responsible for increasing the membrane contact angles in MeOH …”

A comprehensive study was performed on a new application of thin film composite membranes and selecting a stable sublayer for them as pervaporation membranes in organic solvent separation. For this purpose, four different polymeric sublayers of polyethersulfone (PES), cellulose acetate, polyacrylonitrile, and polyetherimide were prepared, and the interaction of methanol (MeOH) and methyl tert butyl ether (MTBE) with them was investigated. The contact angle results, scanning electron microscopy images, and swelling and mechanical strength measurements obviously displayed the effect of immersion in organic solvents on the sublayers. Finally, a polyamide active layer was subsequently deposited on the PES membrane surface as the stable sublayer via interfacial polymerization based on a multistep statistical optimization strategy involving fractional factorial design and a response surface method. The prepared TFC membranes were tested in the pervaporation of a MeOH/MTBE mixture and exhibited excellent performance compared with the current membranes in this context. © 2019 Wiley Periodicals, Inc.

“…Raising CBT increases mutual diffusivities between solvent (NMP) and non-solvent (water) in the casting solution during solidification process which consequently increases the film precipitation rate. In fact, at higher CBTs, for constant polymer content, nucleuses of polymer-poor phase will grow rapidly and increase the formation of macrovoids in the membrane structure, thereupon more porous membrane will be obtained [1,16].…”

In the present study, semi-biodegradable membrane of polyacrylonitrile was prepared by immersion precipitation technique, whereas starch, sorbitol, 1-methyl-2-pyrrolidone and water were used as natural biodegradable polymer, additive, solvent and non-solvent, respectively. Experiment design was done by response surface methodology. Effects of three parameters including starch and sorbitol concentration and coagulation bath temperature (CBT) were investigated on the membrane morphology, contact angle, biodegradability, pure water flux, as well as treatment ability. The results revealed that increasing CBT and concentration factors led to improvement in membrane porosity and thickness. Furthermore, membrane wettability and biodegradability were principally influenced by starch concentration. All three parameters were found to have direct effects on PWF and reverse effects on rejection of pollution indices of the raisin wastewater during the treatment process.
