The University of Copenhagen’s AIR Lab hopes to infuse air pollution-laden cities with pockets of fresh, breathable air. The team discovered a process that is similar to the Earth’s own called the Gas Phase Advanced Oxidation method (GPAO), and it could be used to remove pollution from the air. Using an infusion of oxygen, magnetic charges and UV Light, the GPAO process pulls pollutant-rich dust from the sky, providing city dwellers with fresh, clean air.
According to AIR Lab, their GPAO process enhances the already existing natural cleansing process that the Earth’s atmosphere uses to clean itself, which, in modern times, is obviously not enough to combat pollution on its own. With dense urban areas around the world like Beijing, Cairo, New Delhi and Los Angeles regularly measuring unhealthy pollution levels, it is evident that the Earth’s natural cleansing process could use a boost.
The researchers at the University of Copenhagen seek to replicate this cleansing process by transforming pollutant gas molecules into something easier to remove- dust. The nature of gas molecules, which exist far apart from one another, make them difficult to remove, simple because they are hard to get a hold of. Dust, however, is much easier to grasp and remove.
AIR Lab’s dust-transforming process uses an infusion of ozone and UV light into pollutant gas to magnetize particles and get them to collect on a surface, which can then be cleaned. This method could be focused in residential cities, helping to diffuse pollution to create areas of better quality air for the population to breathe easy.
