Smog Tower: Clean air is a hot topic throughout the world. India is passing through the climate emergency. India is planning to install the smog tower in National Capital Delhi. Smog tower will be a 40 feet high and 20 feet wide structure to clean 32 million cubic metres of air per day.

The World Health Organization (WHO) says that India has 6 of the top 10 most polluted cities in the world. National capital Delhi is sitting on the top of the list.

According to a Greenpeace report published last year;1.2 million people die every year in India due to air pollution.

In the light of such severe air condition; all the institutions, corporate houses, social pressure groups, and the concerned government are striving hard to improve the condition of air quality throughout the country.

Worth to mention that China has passed through such severe air condition and the Chinese government has installed the smog tower in Xi’an in the Shaanxi province.

India is also planning to take the same initiative. A Delhi-based company ‘Kurin Systems’ has recently got the patent of the world’s largest air purifier”.

What is Smog Tower?

It is a structure of concrete that has multiple layers of filters. The size of this structure would be 40 feet in height and 20 feet on each side. In total it requires a compound of around 30×30 metres.

The device will be able to take in air from all 360-degree angles and generate 1,300,000 cubic metres of clean air per hour.

Although its capacity would have the capacity to clean 32 million cubic metres of air per day. 
This giant purifier will have 48 fans to keep the flow of clean air going. The manufacturer of this device claims that it could provide clean air to 75,000 people living in the 3 kilometre radius around it.

How does it filter the air?

The smog tower sucks the polluted air, which is purified by the multiple layers before re-circulated into the atmosphere. 

To purify the air; the highly effective H14 grade Highly Effective Particulate Arrestance (HEPA) filter would be used.

This filter can clean up to 99.99% Particulate Matter (PM) present in the air with the help of pre-filter and activated carbon.

Cost of the Smog Tower

The cost of each smog tower is to be around Rs. 10 to 12 crore which includes filtering equipment, monitoring system and construction of the tower.

The supporters of this device say that it’s a good technology to get some relief from severe air quality, on the other hand, the antagonists of this device say that it is too costly and there is no authentic data available to know its effectiveness.

So we have to wait for some more time to know the real impacts of this smog tower. But it can be said that its a good step to provide clean air to the citizens of the country.
