Electrified membranes (EMs) have the potential to address inherent limitations of conventional membrane technologies. Recent studies have demonstrated that EMs exhibit enhanced functions beyond separation. Electrification could enhance the performance and sustainability of membrane technologies and stimulate new applications in water and wastewater treatment. Herein, we first describe EM materials, synthesis methods, electrofiltration modules, and operating modes. Next, we highlight applications of EMs in water decontamination, purification, and disinfection. Additionally, we discuss state-of-the-art electrification methods for controlling membrane organic fouling, biofouling, and inorganic scaling. We also evaluate the energy consumption of EMs for water treatment and fouling control. We conclude by discussing the challenges for improving the stability and practicality of EMs and by proposing pathways for future research and development. On the basis of our discussion, we suggest that EMs may be viable for ultrafiltration and microfiltration but not for salt-rejecting reverse osmosis and nanofiltration applications. Further, we find that EMs are promising for decontamination and organic fouling control, and these systems could be deployed for fit-for-purpose distributed treatment applications.

“…The membrane plays the roles of filter and anode simultaneously. The electrochemical MF process shows the excellent performance for BPA removal because of the synergistic effect between electrochemical oxidation and membrane filtration [38]. Beqqour et al prepared the low-cost ceramic MF pozzolan membrane using micronized phosphate by dry uniaxial pressing process and sintering.…”

The worldwide one major and important issue is the increasing shortage of freshwater. Water is polluted by various category of pollutant such as heavy metal, organic toxic chemical, dyes and others. In such situation providing better solutions for water treatment is a major challenge for researchers. Various techniques have been used in wastewater treatment applications but among those techniques the membrane technology is the most promising technology. This chapter contains recent progress of membrane technology for advanced wastewater treatment, is systematically summarize. This review includes introduction about different membrane technology such as microfiltration (MF), ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO). Current status of each membrane separation techniques, membrane cleaning techniques, challenges and promising solutions for various wastewater treatment have been discussed.

“…For example, Pan et al. reported the preparation and application of a new electrochemical microfiltration membrane made of coal-based carbon materials ( Pan et al., 2019 ). When treating the wastewater containing 50 mg/L BPA, the BPA and COD removal efficiencies were up to nearly 97 and 90%, respectively.…”

“…Most of the lab-scale studies use synthetic solutions with a 10–100 mM saline as the electrolyte solution to attain a high solution conductivity, although it is much higher than the concentration of realistic matrices (such as surface water and municipal wastewater). Nevertheless, it is reported that coal-based carbon membrane can achieve more than 90% of removal of 50 ppm BPA in tap water solution (with a low electrical conductivity of 255 μs/cm) ( Pan et al., 2019 ).…”
