Iranian Researcher’s Invention to Remove Fine Dust Receives IFIA Award
“This filter is designed in such a way that the particles in the air can be removed by using a series of fluids. For instance, installing this filter in water coolers makes it purify the air using the water in the water coolers,” said Morteza Bakhshi, the winner of the prize.
He described another use of the filter in cars, and said, “This filter is a mechanical part that absorbs fine dust by creating a thin layer of fluids, like oil or antifreeze."
Noting that the existing filters block the passage of air because they become saturated with pollutants after a while, he said, “The filters we designed can be washed and reused and are able to absorb particles as little as 20 microns like fine dust and dust.”
Bakhshi called the absence of pressure drop in the flow of passing air, the absence of paper in the production of innovative filters and as a result the preservation of trees and the ecosystem among other advantages of this filter, and said, “Reducing air pollution is another advantage of this product.”
In a relevant development in July, an Iranian nanotechnology firm also succeeded in production of air filters for evaporative cooling systems with antibacterial properties.
‘Raymand Intelligent Machine’ company made the product which is an air filter containing metallic nanoparticles, and is used in evaporative coolers to eliminate a wide variety of bacterial species or stop their growth in humid media.
The addition of metallic nanoparticles to the main starting material during the fabrication process of air filters has led to enhanced antibacterial activity.
