Delhi which is reeling under severe air pollution may have a huge air purifier tower in the near future. A proposal titled “Project for Demonstrating the Feasibility of Reducing Air Pollution Exposure in Urban Area by Using Large Scale Cleaning System” was submitted by Indian Institute of Technology Bombay (IITB) for control of air pollution under EPC (Environment Protection Charge) funds, and the project aims to develop and deploy large scale air purifying system named Adaptive Clean Air Network (ACAN). The project was examined by the Expert Panel of Department of Science and Technology. The project has been recommended as pilot demonstration for one experimental tower in Delhi. This information was given by the Minister of State in the Ministry of Environment, Forest and Climate Change, Shri Babul Supriyo.
“Ministry of Environment, Forest and Climate Change (MoEF&CC) is in the favour of adopting new technologies which help in mitigating air pollution. The technological suggestions for abatement of air pollution are evaluated in coordination with Department of Science and Technology for examination of the feasibility,” said the Minister in a written reply in the Loksabha.
Ministry has tried several technologies for mitigation of air pollution which inter-alia includes deployment and evaluation of air purification units for traffic junction pollution abatement in Delhi, control of dust emissions using dust suppressant, demonstrate the effectiveness of air pollution mitigation by pariyayantra filtration, multiple antenna high density ion generator for pollution control.
Last year, a 200-foot tower in the central Chinese city of Xi’an was built to pull deadly pollutants from the air. Preliminary research showed that the tower — which some are calling the world’s largest air purifier — has cut air pollution significantly across a broad swath of the surrounding area. Now China is planning to build an even taller air-purifying tower in Xi’an, and possibly in other cities around China.
