Desalination Technology Breakthrough - Membrane Distillation with a Nanofiber Membrane

Nanofiber Membrane Filters 99.9% of Salt from Seawater within Minutes

 

Newly created membrane removes 99.9% of salt from seawater and make it drinkable within MINUTES
  • "Researchers from the Korea Institute of Civil Engineering and Building Technology (KICT) created a new membrane, known as coaxial electrospun nanofiber membrane."
  • "The membrane not only removes 99.9 percent of salt from seawater, but it lasts up to a month, whereas previously solutions only lasted for about 50 hours before they need to be replaced."
  • "The membrane was created by alternative nano-technology, also known as electrospinning, to help prevent the membrane from getting too wet, as well as its long-term stability."
  • "The nanofibers in the membranes allow for a higher surface roughness and the ability to repel water, also known as hydrophobicity."
  • "This technology created by the KICT researchers starts with poly(vinylidene fluoride-co-hexafluoropropylene) as the core, mixed with silica aerogel and a low concentration of polymer as the sheath, which allows the team to get the hyper-repellent membrane surface."
