Efficacy of polymeric nanofibrous membranes for proficient wastewater treatment

Membrane technologies have great potential to treat polluted water due to their characteristic features such as high porosity, flexibility and large mechanical strength. The present review summarizes the most elevated development on fabrication and modification of membrane technologies artificially and naturally, emphasizing their advanced progress, challenges and future improvement in water treatment applications. The article compares the proficiency of different membranes made up of natural or artificial polymers for wastewater treatment and discusses their effectiveness for removing dreads, toxic and widespread heavy metal ions. We compare the electrospun technique against other fabrication techniques, such as interfacial polymerization, phase inversion, stretching, blending and track etching for the preparation of membrane and mainly focusing on electrospinning technique for membrane synthesis which exhibits intriguing properties like high specific surface area, high porosity and robust mechanical strength. The roles of both artificial, as well as natural polymers in water purification, have been summarized. The electrospun nanofiber membrane offers a viable and effective means for wastewater treatment.
