Thus, the air quality control systems (AQCS) offer solutions for controlling and handling of air, gases, and contaminants to provide cleaner air discharge. Air quality control systems include use of air filters, scrubbers, electrostatic precipitators, and other products for maintaining the quality of air.

How does air quality monitoring system work?

The Air Quality Monitoring System (AQMS) is a facility to measure wind speed, direction, other weather parameters, concentration of air pollutants (such as SO2, NOx, CO, O3, THC etc), and particulate matters continuously all year round. Mobile AQMS can also be customized to monitor multiple sites via one system.

What is an example of a device that is used to control air pollution?

The Use of Air Pollution Control Devices

Existing APCDs include electrostatic precipitators (ESPs), fabric filters (FF or baghouse), flue gas desulfurization (FGD), and selective catalytic reduction (SCR). ESPs are designed to reduce fly ash emissions by creating an ionized field that removes charged particles.

What is the most accurate air quality monitor?

Best Overall: Airthings Wave Plus Radon & Air Quality Monitor. To earn the best overall rating, an air quality monitor must be easy to use, compact and well-rated. The Airthings Wave Plus monitor offers all of this and much more.

Which method is used for prevention and control of air pollution?

Latest techniques of air pollution control are: Combustion – This method is applied when the pollutants are organic gases or vapours. The organic air pollutants are exposed to 'flame or catalytic combustion' when they are converted to less harmful product carbon dioxide and product water.

How is air monitoring done?

Air quality is measured with the Air Quality Index, or AQI. The AQI works like a thermometer that runs from 0 to 500 degrees. However, instead of showing changes in the temperature, the AQI is a way of showing changes in the amount of pollution in the air. Air quality is a measure of how clean or polluted the air is.

How does a venturi scrubber work?

A venturi scrubber accelerates the waste gas stream to atomize the scrubbing liquid and to improve gas-liquid contact. In a venturi scrubber, a “throat” section is built into the duct that forces the gas stream to accelerate as the duct narrows and then expands.
