“…A flat sheet membrane of PES was fabricated by phase inversion via the immersion precipitation technique [28][29][30][31]. To prepare the casting solution containing PES in the solvent DMSO, the DES as a pore-forming agent was mixed and added by stirring at 700 rpm for 7 h. The DES was added at a concentration of 1 wt % to all the membranes, except for DES-0.…”

Dairy industry wastewater was treated by a micellar-enhanced ultrafiltration (MEUF) process. Sodium dodecylbenzene sulfonate and Tween-80 were used as anionic and non-ionic surfactants, respectively, along with the dairy industry wastewater sample. A deep eutectic solvent (DES) membrane was prepared by phase inversion via non-solvent immersion precipitation. The DES (choline chloride/urea) as pore-forming agent was synthesized and added into the casting solution at various concentrations and blended to form a membrane, using a dead-end filtration setup. The prepared membranes were characterized to examine the presence of functional groups and the surface morphology. The permeate flux and rejection performance of the prepared membranes were investigated. The newly developed MEUF membrane is promising for the treatment of dairy effluents.

Protein with high purity is currently a valuable commercial commodity, prized for its high value and application in specialized functions. PVDF-based membrane technology has found widespread use in protein purification processes. However, the issue of fouling on the membrane surface frequently hampers the performance of PVDF membranes. The present study aims to enhance PVDF membranes' selectivity and antifouling properties through chitosan modification, thereby optimizing protein filtration. PVDF and PVDF/Chitosan membranes were fabricated using the phase inversion technique, followed by a comprehensive characterization of their surface properties, thermal attributes, and performance in bovine serum albumin (BSA) protein filtration. The collected data revealed notable increases in membrane hydrophilicity, porosity, and pure water flux due to the incorporation of chitosan. The membrane protein rejection capabilities were significantly enhanced to levels exceeding 90% with the introduction of 0.5% chitosan. Moreover, as the chitosan concentration increased, the membrane exhibited superior antifouling characteristics, with the 0.5% chitosan concentration yielding the highest Flux Recovery Ratio (FRR) value of 85.35%. Considering the significant improvement selectivity and antifouling properties in the combined system, the chitosan-modified PVDF membrane holds substantial promise in protein purification applications. <img src="/public/site/images/fitria/rsz_72110.png" alt="" />

The Mil‐125(Ti) metal–organic framework nanoparticles were modified with different compounds i.e. polyamidoamine dendrimer (Mil‐Den), chitosan (Mil‐CS) and Mil‐CS‐Den to prepare functional and hydrophilic nanocomposites. These nanocomposites were characterized and applied for modification of polyethersulfone (PES) membrane by blending them in the dope solutions. The mixed matrix PES membranes were manufactured by the nonsolvent‐induced phase inversion method. The introduction of the nanocomposites into the membrane structure led to positive alterations such as the improvement of hydrophilicity and morphology causing the development of permeability and antifouling properties. The bare PES membrane contact angle was decreased from 60° to 34.5° by adding 0.5 wt% of Mil‐CS‐Den nanocomposite. Applications of novel structures with special absorption in 0.5 wt% of Mil‐CS‐Den membrane, caused an increment of porosity, mean pore size and reduction of surface roughness. The permeability was enhanced from 4.2 to 21.43 L/m2 h bar, while fouling was reduced from 48.5% to 13.5% which indicates the strengthening of the antifouling feature of the hydrophobic PES membrane. Also, the flux recovery ratio was enhanced from 66.7% to 89.3% by blending 0.5 wt% of Mil‐CS‐Den. The modified membranes showed an excellent dye separation performance. The attachment of dendrimer and chitosan to the Mil‐125(Ti) surface increased the efficiency of Mil‐125(Ti) in the modification of the PES membrane. The utilization of nanomaterial features can reduce the limitation of membrane processes and reach desirable outcomes. The results of this work indicate the high potential of the modified MOF for the removal of dye contaminants as well as provide a suitable perspective for water purification with the help of membrane processes.
