Pollution is the biggest problem the world faces today. Pollution is deemed to increase with the increase in population. Technological advancements are ought to create many problems to the environment through hazardous chemicals it uses. Nevertheless, it is that technology that comes into rescue in the contemporary times to curb the rising pollution. GPAO cleaning system uses light to clean air.
GPAO is invented by a Professor of environmental chemistry Matthew Johnson, University of Copenhagen, Denmark. He published the results of testing GPAO in the article “Gas Phase Advanced Oxidation for effective, efficient In Situ Control of Pollution” in the scientific periodical “Environmental Science and Technology.”
GPAO is a cleaning system, which has derived its functionality from the ecosystem itself. Matthew says “Nature cleans the air in a process involving ozone, sunlight, and rain. Except for the rain, GPAO does the very same thing, but speeded up by a factor of a hundred thousand.”
GPAO system starts the process by mixing the polluted gas with ozone in the presence of fluorescent lamps. This allows the formation of free radicals. Consequently, these free radicals attack pollution, forming sticky products as they clump together. The products form fine particles which grow into a type of airborne dust. Dust is easy to remove from the air. All it needs is an electrostatically charged surface to stick to. Once it sticks, it goes nowhere.
Matthew explained that “Anyone who has ever tried dusting a computer screen knows how well dust sticks to a charged surface. This effect means that we don’t need traditional filters, giving our system an advantage in working with large dilute airstreams.”
GPAO system besides cleaning dust from the air also eliminates the foul smell. GPAO is being used in industries to treat waste polluted water. GPAO comes with an added advantage. As it also helps to remove viruses, fungal spores and bacteria.
