In an effort to combat pollution the capital city has finally introduced its first smog tower. Situated in Lajpat Nagar Central market, it is 20 feet tall and has been erected on a 4 feet high pedestal on a covered drain.
According to media reports, the tower is fitted with exhaust fans to suck in polluted air and can remove up to 80% of the particulate matter, namely PM 2.5 and PM10, which wreak havoc in Delhi each year. The smog tower has been installed after the Supreme Court’s directive to find effective ways to combat the city’s problem which leaves many with respiratory problems.
The cost of setting up the facility was Rs 7 lakh and the running cost is about Rs 30,000, according to a news report. The tower runs on electricity and may treat 250,000 to 600,000 cubic metres of air per day, the report added. The cylindrical setup will purify the air within a vicinity of 750 metres.
A pilot project to test the effectiveness has also being undertaken at IIT Delhi in collaboration with IIT Bombay and University of Minnesota.
