Govt explores bus roof mounted air purification systems to tackle air pollution: Jitendra Singh
New Delhi: Union minister Jitendra Singh on Thursday said that the government is exploring the potential of bus roof mounted air purification systems (BRMAPS) to capture particulate matter in the highly polluted cities. In a written reply to a question in the Rajya Sabha, the minister said, the Central Pollution Control Board (CPCB), a statutory body under the ministry of environment, forest and climate change (MoEFCC) has installed pariyayantra filtration units on top of 30 buses to filter dust in Delhi-NCR.
Singh said, CPCB conducted pilot trials of various new technologies for management and improvement of air quality in Delhi-NCR through premier institutions. A pilot study was conducted on the deployment and evaluation of Wind Augmentation and Purifying (WAYU) units for traffic junction pollution abatement in Delhi.
He added, under this study, 54 units were installed which operated at five traffic intersections in Delhi i.e., ITO, Anand Vihar, Shadipur, Wazirpur Chowk and Bhikaji Cama Place for reduction in air pollution. A pilot study was conducted on control of dust emissions using dust suppressants.
Under this, application of dust suppressant (salts of calcium/magnesium and bio additives) was done at three sites: Sarai kale khan road, DDA construction site at Narela and Dilshad Garden flyover to Shaheed nagar metro station to check the control on dust emissions. Installed a negative ion generator at IIT Delhi, Sonipat campus for accessing the impact of generated Negative Air ions (NAIs) on ambient air quality.
