India’s first functional smog tower inaugurated near Anand Vihar Metro Station in Delhi

New Delhi: Amid widespread concern over pollution levels in the national capital, Delhi got the country’s first functional smog tower near a metro station. Union Minister for Environment, Forest and Climate Change Bhupendra Yadav virtually inaugurated the Smog Tower at Anand Vihar on Tuesday.

A smog tower is a structure designed largely as an air purifier to reduce pollution particles in the surrounding areas. An ANI report states that built by the Tata company, the tower has a capacity of 1,000 cubic meters per second. Forty fans are fitted to provide a design airflow rate of 1000 m3/sec.

The filtration system being used in the smog tower has reportedly been designed by the University of Minnesota with a potential efficiency of 90 percent. A tower with a height of more than 20 meters is of downdraft type in which pollution or particulate matter enters from the top of the tower and clean air emerges from the bottom.

On Tuesday, the government also launched PRANA, a portal to track the progress of the National Clean Air Programme, with Environment Minister Bhupendra Yadav saying the country is committed to ensuring clean air and blue skies for everyone.

During the launch event organized at the ministry headquarters here on the occasion of ‘International Day of Clean Air for Blue Sky’, Yadav said it is an experimental technology and its impact will be seen for two years. “India is committed to ensure clean air and blue skies for all the people of the country, assuring them of a healthy and productive life,” Yadav said during the event.

Yadav later tweeted, “The focus of Prime Minister Shri @NarendraModi ji’s government policies is with sustainable use, conservation and protection of public goods and environment. Glad to share that Clean for Blue Sky A smog tower was inaugurated on the International Day of Air. Delhi.”

The Union Minister said that in 2018, only six out of 132 cities had particulate matter (PM) concentrations below the national ambient air quality standards, which increased to 11 cities in 2019 and 28 in 2020, with 86 cities performing well. has done. Air quality in 2019 compared to 2018, which increased in 2020 to 104 cities.

Yadav further said, “We should look at how policy interventions can help address the issue of air pollution. Air, water, earth are all public goods that can be saved with preventive policies,” said the Hum Pran portal. Launching and installing smog. Tower in Delhi’s Anand Vihar. This smog tower is an experiment to see if the technology can be used in the future and reduce pollution. We are committed to clean air for blue skies. “

Speaking at the event, Minister of State for Environment, Ashwini Choubey said that a day like the International Day of Clean Air for Blue Skies is celebrated only when the situation is dire. Central Pollution Control Board Chairman Tanmay Kumar was also present in this program.

Notably, the smog tower was to be installed in 10 months, as directed by the Supreme Court, after which the tower’s performance was to be evaluated for two years. The ministry sought an extension of three months from the court in view of the second wave of the COVID-19 pandemic.

The tower, proposed by IIT Bombay, is of downdraft (polluted air comes from the top of the tower and clean air comes from below) for local reduction of PM2.5 and PM10.

An advisory committee headed by CPCB Chairman, and comprising experts from IITs, National Environmental Engineering Research Institute (NEERI), Ministry of Environment, Forest and Climate Change, Engineers India Limited (EIL), NTPC Limited and NBCC India Limited. It has also been constituted to monitor progress, review performance and guide on improvement and optimization.

Earlier, the 24-metre tall Smog Tower, the first such structure in the city, was installed in the Connaught Place area. On 23 August, Delhi Chief Minister Arvind Kejriwal inaugurated the Smog Tower at Connaught Place.
