Nonwoven mats of thin nanofibers are formed after accumulation on a collector, which possess a high surface-to-volume ratio and porosity. These unique characteristics make them useful for various applications, including air and water filtration for removing particulate matter, toxic ions, and molecules, while demonstrating high selectivity and durability.

In wastewater treatment, electrospun nanofiber mats have shown promise in filtering particulates ranging from 3 to 10 μm in size, as well as removing heavy metals, ions, and organic pollutants such as dyes, pesticides, and plasticizers through physisorption, chemisorption, and electrostatic attraction mechanisms. Overall, the use of electrospun nanofiber mats in filtration and wastewater treatment presents an effective and sustainable solution for environmental remediation.
