China's fight against air pollution. Will it work for us?Many major cities in China are battling with air pollution. In almost 338 cities with poor air quality, the government measures have resulted in a decline (6.5%) in the levels of pollutants
One of the measures is the use of the ' Mega Purifier'. This tall device (around 300 feet) that looks like a chimney from a distance with greenhouses at the base of it. The air is sucked into the tower, heated up and then pushed up via layers of filters. This device effectively reduced the levels of PM 2.5 (tiny and hence harmful to humans).
Based on the weather and degree of pollution it can clear round 5-18 million cubic meters of air every day.This clears the air within the area of around 10 square kilometers.
This is run by the Insitute of Eath Enviornment, Chinese Academy of Sciences. A new giant 1640 foot version has been planned, when succesfully working, this is hoped to help to maintain air quality of a small city.
Once we know the cost and the feasibility of having this in our Indian Metros, it could become a significant step in India's plan to tackle air pollution. It would be worth a try at least in Delhi.
