An electrochemical membrane filtration system provides an innovative approach to enhance contaminant removal and mitigate membrane fouling. There is an urgent need to develop portable, versatile, and efficient electrochemical membranes for affordable wastewater treatment. Here, a 3D conductive gradient fiber membrane (CC/PVDF) with a gradient porous structure was prepared using a two-step phase inversion method.

Membrane fouling and the trade-off between membrane permeability and selectivity restrict the potential applications of membrane filtration for water treatment. ZIF-8 was found having great permeability and antibiofouling performance, but with issue on particle aggregation makes it difficult to achieve high ZIFs loading and fabricate a defect-free molecular sieving membrane in previous research. In this study, we formed a scalable antibiofouling surface with improved permeability and fouling resistance on a PEI-ZIF-PAA membrane using a layer-by-layer assembly technique.

Polyurethane (PU) nanofibers possess large specific surface area and excellent mechanical properties which have been used as the matrix for many applications. Phytic acid is the biocompatible and environment-friendly organic acid with excellent chelating ability of heavy metal ions due to it contains 6 phosphate groups. In this study, the PU/phytic acid nanofibrous membrane has been successfully produced by electrospinning which was used for Pb removal.
