“…This trend is explicable by the fact that reversible pollution predominantly correlates with hydrophilic contaminants within the feed liquid. As the hydrophilicity of the membrane surface increases, there was a greater tendency for hydrophilic substances to adsorb onto the surface, thereby intensifying the degree of reversible fouling 53 . The decrease in irreversible fouling was primarily attributed to the formation of a hydration layer on the membrane surface, characterized by an enhanced hydrophilic nature 34 .…”

The intricate interplay between chemical composition and the incorporation of functional fillers plays a pivotal role in shaping the structural attributes and separation efficacy of mixed matrix ultrafiltration membranes. In this work, we report the utilization of a novel organic filler of hydrophilic modified polyimide particles (PI‐SO3) for the first time in the preparation of mixed matrix ultrafiltration membranes. A series of ultrafiltration membranes were fabricated using polysulfone as the matrix material and PI‐SO3 as the additive. The addition of PI‐SO3 to the mixed matrix membrane effectively enhanced both water flux and antifouling ability. The ultrafiltration membrane with 0.2% particle content exhibited the highest pure water flux at 535.5 L h−1 m−2, owing to the synergistic regulation of pore structures and surface hydrophilicity. The ultrafiltration membrane with 0.5% PI‐SO3 particles demonstrated the highest flux recovery rate at 76.8%, attributed to the superior hydrophilicity displayed by the added particles within the ultrafiltration membrane. The increased particles content correlated with improved hydrophilicity on the membrane surface, resulting in enhanced antifouling performance. The hydrophilic modified particles effectively regulated pore structures, surface hydrophilicity, and surface charge, ultimately enhancing the performance of mixed matrix ultrafiltration membranes for wastewater purification. Therefore, the use of modified polyimide particles as fillers introduces an innovative method to economically enhance ultrafiltration membranes, providing a potential solution to mitigate the economic costs associated with trade‐off effects during the modification process.

“…11 In addition, the maximum allowed amount of treated wastewater for urban and environmental uses is 1-2 mg L −1 . 12 There are various solutions, such as filtration, 13 sedimentation, 14 oxidation and reduction, 15 ion exchange, 16 adsorption, 17 and separation of membranes, 18 to reduce the amount of metal ions in effluents and wastewaters. The ability to remove most of the metals, high efficiency, and affordability of the adsorbent make adsorption an effective process for eliminating heavy metals from wastewater.…”
