As Delhi gears up for the air pollution season, the city installed its first smog tower in Connaught Place.  The smog tower has been installed months before the crop burning season, when pollution levels in Delhi rise cross the hazardous mark.

The Delhi government will study the impact of the smog tower on pollution and could add more such structures across the national capital.

The smog tower was inaugurated by the Chief Minister of Delhi, Arvind Kejriwal.

“Supported by technology never seen before in India, this Smog Tower is the first of its kind in the country. The technology for this ambitious project was brought from America. The tower is 24 metre high and will take in air from a radius of one kilometre, which it will clean and then give back fresh, clean air to the area,” said Kejriwal, after inaugurating the first tower.

The tower has a capacity of cleaning 1000 cubic metres of air per second. 

Established as a pilot project, detailed studies will be conducted on the performance of this smog tower. 

IIT Delhi and IIT Bombay will analyse all the data and submit a report on the effectiveness of the Smog Tower. Once satisfactory results are received about the tower’s effectiveness, then the model will be replicated and smog towers will be established all over Delhi. 

Key features of the tower:

  1. Based on a downdraft air flow model in which 40 huge fans shall induct air from the top of a special type of canopy structure 
  2. Constructed at a height of about 24 meters 
  3. Will release clean air at about 1000 metre cube per second filtered through novel geometry filters of two layers
  4. The area of influence is expected to be about one kilometer radius around the tower
  5. The tower is also powered by 5000 filters
