Summary: A facile modification strategy using PDA and SB3-14 was reported to enhance the anti-fouling properties of a PES membrane. The modified membranes showed improved anti-fouling performance without compromising transport properties, with the optimal results observed for membranes modified with low SB3-14 concentration. The presence of SB3-14 significantly decreased Lewis acid-base energy during fouling construction.

Summary: This study reports a membrane modification strategy using polydopamine and a zwitterionic surfactant to enhance the anti-fouling properties of a polyethersulfone membrane. The modified membrane showed significantly reduced flux decline and fouling resistance compared to the pristine membrane. The optimal anti-fouling performance was achieved when the concentration of the zwitterionic surfactant was low.

Summary: This study explores the efficacy of grafting zwitterionic polymer brushes on Graphene oxide blended Poly-ether sulfone (PES) membrane to develop better-performing ultrafiltration (UF) membranes with enhanced anti-biofouling potential. The grafting of polymer brushes improves the hydrophilicity and surface topology of the membrane, resulting in increased water flux and improved resistance against biofouling.

Summary: Bimetallic oxide nanoparticles, particularly Fe2O3-Mn2O3, were synthesized and used as nanomodifiers for PES ultrafiltration membranes, significantly enhancing water contact angle, surface roughness, porosity, and pure water flux for the membrane containing 0.25 wt% nanoparticles. The modified PES membranes exhibited improved antifouling ability and higher flux recovery ratios in protein-based filtration tests.

Summary: The aim of this study was to investigate the influence of the molecular weight cut-off (MWCO) of membranes on the ultrafiltration (UF) performance and fouling degree of car wash wastewater. The results showed that using membranes with MWCO of 10 kDa provided high-quality permeate and excellent turbidity removal.

Summary: The appearance of composite membranes offers a new approach for reducing membrane fouling. In this study, polyaniline (PANI) and Ti3C2Tx (MXene) were combined using electrostatic assembly to create a conductive network and adjust the distance between MXene layers. The resulting MXene-PANI/PES membrane exhibited significantly improved permeation flux and retention rates compared to a regular PES membrane, while also demonstrating enhanced conductivity and anti-fouling capabilities.

Summary: The electrode ultrafiltration membrane bioreactor (EMBR) showed better performance and membrane fouling characteristics in treating cosmetics wastewater, with increased COD removal efficiency and reduced transmembrane pressure compared to the conventional ultrafiltration membrane bioreactor (UMBR). The electrode ultrafiltration membrane had a higher energy barrier with pollutants, contributing to its strong anti-fouling property.

Summary: A newly developed water-soluble polymeric nano-additive called PCLNPG has been used as a pore former to modify a polyethersulfone ultrafiltration membrane for dye removal. The study found that the content of PCLNPG in the membrane affected its surface characteristics, morphological structure, and overall performance. Increasing the PCLNPG content improved the hydrophilicity and porosity of the membrane. Additionally, the increased porosity of the membrane was the main reason for the reduced contact angle. The prepared membrane with 3% PCLNPG showed significantly improved water flux and dye rejection, making it a potential option for treating textile wastewater.
