India’s capital Delhi’s worsening air quality has borrowed several criticisms throughout the world in recent years. In this situation, a national laboratory Tuesday certified an air purifying technology to turn public places to clean air zones, brings some relief to citizens.
On Tuesday, Delhi’s air quality was one of the worst due to stubble burning. Data published by the Central Pollution Control Board showed a severe air quality in seventeen areas of national capital strengthening the fact.
PM1 and PM2.5 particles are the two most dangerous dust particle for the human. Their presence in the ambient air makes human life vulnerable. To removing these particles from the air by applying this technology is the main focus.
Fine particles with a diameter of 2.5 micrometers and less are PM2.5 and diameter less than 1 micrometer or less are PM1. Since they are very small in size, it can easily come inside through human respiratory and triggers chronic diseases such as for as asthma, heart attack, bronchitis, and other respiratory problems.
Chief Secretary at the National Physical Laboratory, Shankar who certified it said “The collection results from aerodynamics particle size of PMof PM1 and PM2.5 reports the efficiency of the ‘Clean Air Zone’ technology to be more than 90 percent.
The technology is developed by Evergreen Systems. Under a pilot project, it is being used at Gurudwara Rakabganj Sahib. It can also be used in public places likes hospital, schools, bus stands, municipalities and able to mark it ‘ clear air zone’.
This technology uses the law of fluid dynamics to take control of air flow, the company said in a statement. It comprises of a high design which is based on high optimization of high-performance computing and air filters.
The implication of separation is done through a proprietary dual purifier system combining nano-particles for removing 97 to 99 percent dust particles.
A chemical media is also used to remove NOx, SOx, CO2 gases. It utilizes atmospheric chemistry airflow engineering to produce the high-end design to separate harmful fine particles.
