Air Quality Standards For Steel Plants

Steel plants and other heavy industries have to abide by certain guidelines laid down by the government associations like the Central Pollution Control Board (CPCB). United States Environment Protection Agency (US EPA), and World Health Organization (WHO). Air quality monitors help significantly and demonstrably measure emissions per tonne of steel.

Central Pollution Control Board (CPCB) has set certain standards in order to keep the emission in control thereby keeping the pollution in check. According to the National Ambient Air Quality standards, PM10 concentration in the ambient air in industrial and other ecological areas notified by the government should be 60μg/m3 when measured annually* and 100μg/m3 for the duration of 24 hours**. Whereas for PM2.5, the concentration should be 40μg/m3 annually* and 60μg/m3, when measured in 24 hours**

World Health Organization (WHO) prescribed PM concentration levels in the ambient air: fine particulate matter or PM2.5 is 5 μg/m3 when measured annually and 15 μg/m3 on measuring in a 24-hour duration. For PM10 or coarse particulate matter the prescribed concentration levels are 15 μg/m3 on annual measurement and 45 μg/m3 when measured in 24-hour duration.

The United States Environment Protection Agency (US EPA) PM concentration guidelines are: 25 μg/m3 in 24 hours duration and in annual monitoring the prescribed PM concentration levels are 8 μg/m3.

*Annual Arithmetic mean of a minimum of 104 measurements in a year at a particular site taken twice a week 24 hourly at uniform intervals.

** 24 hourly or 8 hourly or 1 hourly monitored value, as applicable, shall be complied with 98% of the time in a year. 2%of the time, they may exceed the limits but not on two consecutive days of monitoring.

Impact of Pure Skies On Particulate Matter

Air Quality Improvement in a Chemical Plant

There has been a reduction in 24-hour average values of PM2.5 by 65% &  PM10 by 66% in the steel plant. The orange bar represents the levels of Particulate Matter prior to installing Pure Skies and the blue bar represents the levels of Particulate Matter after Pure Skies has been installed.
