Summary: This study investigates the use of spray-modified non-solvent induced phase separation (s-NIPS) to create large patterned PVDF membranes and magnetically induced membrane vibration (MMV) to enhance their anti-fouling properties. The results show that patterned membranes reduce fouling rate and increase critical flux, while membrane vibration further improves anti-fouling potential and delays irreversible fouling.

Summary: Impregnation of noble metal silver nanoparticles (AgNPs) into polymeric membranes is an effective method for producing safe drinking water. The study showed that membranes with AgNPs-1 and AgNPs-2 exhibited improved mechanical properties and pure water flux when fabricated at higher temperatures. Despite different levels of silver release during fabrication, all membranes showed no leaching during dead-end filtration and demonstrated excellent antibacterial performance against E. coli.

Summary: A novel CO2-responsive copolymer was successfully synthesized and used in the fabrication of a blend membrane with switchable water flux. The protonation reaction of PDEAEMA segments within the membrane pores after CO2 aeration led to pore shrinkage and reduced water flux. By taking advantage of the CO2-stimulus responsiveness, a green cleaning method using alternate aeration was adopted to clean protein on the membrane surface, achieving a satisfactory flux recovery rate comparable to traditional cleaning methods.

Summary: This study introduces a novel ultrafiltration membrane called NFFM, which utilizes a nanofiber layer as an integral filler in the phase inversion process. The photoactive NFFM made using photoactive PAN-C3N4 NF showed special morphologies and better dye rejection property compared to other membranes. This primitive study provides a new method for preparing a new type of membrane with potential applications.

Summary: We have successfully fabricated a series of highly efficient polyvinylidene fluoride (PVDF) membranes by varying the substrate morphology. Sandpapers with a wide range of grit sizes (150-1200) were used as casting substrates to tune the effect of abrasive particles on the casted polymer solution. The impact of these particles on porosity, surface wettability, liquid entry pressure, and membrane morphology were investigated. The developed membranes on sandpapers showed excellent membrane distillation performance for desalinating highly saline water (70,000 ppm), with stable salt rejection up to 100% and a 210% increase in permeate flux over 24 hours. These findings provide insights into the role of substrate nature in controlling membrane characteristics and performance.

Summary: Superhydrophobic PVDF membrane with micro-nano structures was prepared by adding NaCl-H2O to the casting solution, leading to high water contact angle and increased DCMD flux. NaCl crystals acted as nuclei, accelerating the crystallization of PVDF chains and forming a stable superhydrophobic structure.

Summary: In this study, the solubility of boehmite nanoparticles in 20 different solvents was experimentally determined using the Hansen solubility parameter method (HSP), with the algorithm optimized using MATLAB. The Flory-Huggin's theory was applied to model the quarternary system of a blend polymeric membrane, and thermodynamic equations were solved and optimized using MATLAB to obtain ternary phase diagrams for different filler compositions. Thermodynamic enhancement and kinetic hindrance parameters were used to predict the membrane morphologies. The results showed that the addition of nanoparticles increased the porosity of the membrane and decreased the contact angle.

Summary: Nanoparticle-incorporated porous polymeric membranes are used for efficient and selective adsorption of toxic molecules in the reclamation of contaminated water. A material selection strategy using thermoplastic polyurethane, Laponite, graphene oxide, and their co-dispersion-derived hybrid was adopted to prepare a high-performance membrane system. The addition of Laponite/GO substantially improved the properties of the membranes.

Summary: The critical flux is an important factor affecting fouling in membrane bioreactors (MBRs). Determining and operating below the critical flux is essential to prevent severe fouling. This study evaluated the critical flux and pollutant removal in a lab-scale submerged membrane bioreactor using real oil refinery wastewater. The results showed that incorporating TiO2 nanoparticles into the PVDF membrane improved phenol removal efficiency and reduced fouling.
