Research Shows that A New Device Can Filter Saltwater 1000 Times Faster than Existing Methods

Scientists have invented a gadget that filters Saltwater 1,000 times faster than currently utilized devices, which could be a huge step toward tackling the problem of freshwater scarcity. Desalination is a procedure that purifies Saltwater to make it drinkable on a large scale.

It entails removing salt to create fresh water, which is then processed in plants before being utilized for drinking or irrigation. Scientists found a novel approach to filtering saline water in a faster and more effective way in a recent study. In a recent study published in Science, scientists developed a new method for purifying saline water that is both faster and more effective.


  • A novel method for purifying saline water has been developed by scientists.
  • They cleverly employed fluorine-based nanostructures.
  • The new approach consumes less energy and is simple to use.

They Used Fluorine-Based Nanostructures Cleverly to Successfully Extract the Saltwater


Associate Professor Yoshimitsu Itoh of the University of Tokyo’s Department of Chemistry and Biotechnology and his colleagues started by looking into the nanoscale potential of fluorine pipelines or channels. “We wanted to explore how successful a fluorous Nano channel would be at filtering diverse chemicals, especially water and salt.”

“We felt it was worth the time and effort to develop a working sample after running some extensive computer simulations,” Itoh added. The researchers produced test filtration membranes by chemically manufacturing nanoscience fluorine rings, stacking and implanting them in an otherwise impermeable lipid layer.

Nanorings varying in size from 1 to 2 nanometres were used to create many test samples. Itoh then looked for chlorine ions on both sides of the barrier, which are a major component of salt in addition to sodium. They discovered that the smaller test sample was working because it successfully repelled incoming salt molecules, according to Itoh.

“Seeing the outcomes personally was thrilling,” Itoh remarked. He also mentioned that the larger ones outperformed alternative desalination techniques, such as carbon nanotube filters. The fluorine-based filters not only purify the water but also purify it thousands of times faster than industrial systems, according to Itoh.

Desalination devices based on carbon nanotubes were 2,400 times slower than those based on fluorine, he claimed. Furthermore, the new approach uses less energy and is simple to use.

Itoh, on the other hand, pointed out that synthesizing the substance used in the sample was energy-intensive in and of itself. He also intended to focus on that component in future studies to reduce the device’s overall operating costs.
