New device can filter salt water 1000 times faster than existing methods: Research

In what could be a major step towards solving the problem of freshwater scarcity, scientists have developed a device that filters saltwater a thousand times faster than conventionally used equipment. Is. On an industrial scale, seawater is made potable through a desalination process. It involves extracting salt to produce fresh water which is further processed into plants and used for drinking or irrigation. In a recent study, scientists invented a new method to purify salt water faster and more effectively.

Scientists in a recently published study sciencedeveloped a new method to purify salt water faster and more effectively. They simply used fluorine-based nanostructures and successfully separated the salt from the water.

Associate Professor Yoshimitsu Itoh of the University of Tokyo’s Department of Chemistry and Biotechnology and his colleagues began by exploring the potential of fluorine pipelines, or channels, at the nanoscale.

“We were curious to see how effective the Fluorus nanochannel could be at selectively filtering out various compounds, particularly water and salt. And, after running some complex computer simulations, we decided it was a working It’s well worth the time and effort to make the sample.” Told Itoh.

Researchers have chemically fabricated nanoscopic fluorine rings, stacked and implanted them in an otherwise impermeable lipid layer, and created test filtration membranes. This structure was similar to organic molecules found in the cell wall.

Several test samples were developed with nanorings ranging in size from 1 to 2 nanometers. Itoh then investigated the presence of chlorine ions on either side of the membrane, which is a major component of the salt other than sodium.

According to Itoh, they found that the small test sample was working because it successfully ejected incoming salt molecules. “It was exciting to see the results for the first time,” Itoh said. They also noted that the larger ones also performed better than other desalination methods, including carbon nanotube filters.

Fluorine-based filters not only purify water, but according to Itoh, it also worked several thousand times faster than industrial equipment. Carbon nano-tube-based desalination devices were also 2,400 times slower than devices with fluorine, he said. In addition, the new method requires less energy to operate and is easier to use.

However, Itoh highlighted that the synthesis of the material used in the sample itself was energy-intensive. He hopes to work on that aspect in further research and reduce the overall cost of operating the device.
