Delhi gets first ‘Smog tower’ in Lajpat nagar

The first 'Smog tower' was installed at Lajpat Nagar, central market in New Delhi.


The gaint 20ft tall tower was installed by the Trader’s association Lajpat Nagar (TALN) with the involvement of East Delhi MP Gautam Gambhir. The facility will be initiated by the cricketer turned politician at noon today.

General secretary of Traders Association Lajpat Nagar, Ashwani Marwah says the initiatives were the need of the hour as the alarming pollution in city, which is also become the pollution capital.

The air pollution levels have been in an alarming stage in the city as in last 48 hours the air quality has remained in the ‘severe’ category. However, Delhi’s air quality showed an improvement on Friday morning. According to the Air Quality Index (AQI) data, major pollutants PM2.5 was 302 in ‘very poor’ category and PM 10 was at 283 in ‘poor category’ in Lodhi Road areas.

In November, The supreme Court had asked the Delhi government to to come up with road map as Delhi is a congested where space is at premium so the towers were to be installed to combat air pollution. The Smog towers will be installed on the lines of China, the country which has experimented with this technology.

Anumita Roychowdhury, executive director (research and advocacy) at Centre for Science and Environment said that there was no data available to establish that these towers clean up outdoor ambient air quality.

“In a city like Delhi where the pollution is at peak, weather is dynamic and sources of pollution multiple, investing in such devices is not feasible. There is no such data published that says that this technology improves air quality. The same money must be used in reducing emissions. We need to take some real actions on cut down of emissions”, said Roy chowdhury.

The Smog tower is about 20ft and total height off the road is about 24ft. Which is built on the four feet high platform on a covered drain on Veer Savarkar Marg. The total cost of tower is Rupees 7 lakh. The running cost of the Air purifier will be around 30,000 which will be borne by the Trader’s association.

The shape is cylindrical with big inlet and four outlet units. The gaint air purifier is fitted with exhaust fans to suck in polluted air with the big inlet unit. The colours chosen is of the tricolor –orange on the top, white in the middle, green colour just above the bottom and blue at the bottom. The tower will run on electricity.

This smog tower will purify the air within a circumference area of almost 500 meters to 750 meters. The purifier aims at treating 2,50,000 to 6,00000 cubic meter air per day and release fresh air in return. Last year China built largest Smog tower over 328 ft High at Xian in Shaanxi.
