Air pollution affects human and environmental health and safety, which is why state and federal agencies have implemented measures to reduce pollution and improve quality of life. Air compliance is an air permitting guideline used by countries to control the emissions of pollutants. In the USA, the Clean Air Act (CAA) provides measures for regulating air pollution. This act also controls how much emission is collectively released into the air by industries such as steel mills and chemical plants.
Air compliance systems
These systems measure the amount of emission released into the air. They include air compliance inspection systems that reduce the amount of air pollution in the atmosphere.
There are two types of air compliance systems:
- Continuous emissions monitoring systems
- Emissions control systems
Continuous emissions monitoring systems (CEMS)
CEMS are air compliance systems installed at the emission source. These systems record the concentration of emissions in the air by pollutants, including particulate matter and gaseous compounds. Continuous emission monitoring systems use guidelines set by:
- EPA standards
- New Source Performance Standards
- The Compliance Assurance Monitoring Rule
- New Source Review
- National Emission Standards for Hazardous Air Pollutants
Emissions control systems
Emission control systems are air filtration systems. These filters trap contaminants as they pass through them. In addition, emissions control systems convert pollutants into safer and environmental-friendly forms.
Examples of emissions control filter systems include:
- Air scrubbers
- Odor control systems
- Mist collectors
- Electrostatic precipitators
Air scrubbers consist of dry scrubbers and wet scrubbers. As the name suggests, dry scrubbers use a dry reagent. The cleaner contains ingredients such as limestone, which have adhesive properties. Pollutants clamp onto the dry reagent and grow into large particles. These particles are trapped by the filter hence cleaning the air.
Wet scrubbers use a liquid cleaning solution to trap impurities in the air. As air passes through the liquid scrubbers, it becomes cleaned of pollutants. This allows purified air to be released into the atmosphere.
Odor control systems
Odor control systems clean out the bad odor in the air. These systems work by releasing a sweet-smelling odor to counter the foul one. In addition, odor control systems purify the air by absorbing stinky pollutants.
These emission control systems absorb mist or vapor from air and gas streams. The system contains coalescers that convert mist and vapor into droplets. Emission control filters separate these droplets from the air passing through the filters.
Electrostatic precipitators purify the air by absorbing visible pollutants. These precipitators positively charge airborne pollutants, which then clamp onto negatively charged precipitator plates. Electrostatic precipitators can remove smoke, power, debris, ash, or dust from the air.
Importance of air compliance
Air compliance is necessary for our well-being. These compliance guidelines monitor and control the amount of pollutants emitted in the air. Air compliance improves indoor air quality, which is a significant advantage, especially for people with respiratory or heart problems. In addition, improving indoor air quality is essential for at-risk persons such as young children and the elderly.
Purifying air is part of environmental compliance. Pollutants can cause ecological damage when they contaminate air, soil, and water. By reducing environmental damage, air compliance guidelines lead to thriving economies.
