Problem:

Home to 21 of the world’s 30 most polluted cities, New Delhi was the world’s most polluted capital city for the second straight year in 2019, according to IQ AirVisual, a Swiss-based group that gathers air-quality data globally. India was also said in the study which focused on the amount of PM2.

Solution:

Anti-smog gun

Alongside the solutions of cleaning up the most polluting factories and transitioning to electric vehicles, the anti-smog gun was first tested in New Delhi in 2017. It was designed to create a ultra-fine fog consisting of very fine water droplets( 10 Micron size) These tiny water droplets were spread in larger areas with the help of a high speed fan and absorb even the smallest dust particles in the air, yet fall to the ground without wetness.

The solution was first patented in 1971 by Jo F. Mercer of Gonzales, Texas USA as “a method and apparatus for removing smog and smoke” US3572264A

Connected to a water tank and mounted on a vehicle, the 360° Indian version can be taken across the city to spay water to settle dust and other suspended articles such as PM 2.5.

Built by Cloud Tech in Haryana, India, a range of 5 skid/tower/trolley/trucks are available – whilethe 3kW model has a range of 20 metres,the 50kW can project its spray to 100 metres.

During the 2020 peak of pollution, smog-guns were installed at 14 large project sites in Delhi
