To reduce the spread of viruses, bacteria and molds, Chennai Metro Rail has installed a micro-plasma oxidation system in metro stations.

To begin with, they set up this system from Tirumangalam to Chennai Central. Soon it would be settled from Saidapet to Washermenpet. The system helps disinfect the air and surface of stations, according to a press release.

“Through proper dilution of micro-plasma oxidation in water, the air passing through the ventilation system of subway stations is sterilized and safe,” the statement said.

This system uses tap water as a feed and helps mitigate infections that spread through the air and surfaces. “CMRL has researched and tested the disinfection system, which has shown a 99% reduction in microbial load such as bacteria, fungi, viruses, protozoa, and bacterial and fungal spores, by mounting the system on the units of air handler (AHU) of the centralized air conditioning system in metro stations,” the statement read.

The Government of India’s Department of Science and Technology and the National Science Foundation in the United States have validated the micro-discharge plasma technology that has been deployed.
