Types of Air Pollution Control Equipment

Air pollution is the most pressing issue facing contemporary society that demands an immediate resolution. Air pollution can originate from natural sources—such as volcanic eruptions and wildfires—as well as from human activities (both mobile and stationary). Air pollution control remains the only way of air treatment.

Each industrial process generates various air pollutants, which is why there are multiple types of air pollution control devices for both mobile and stationary sources across different industries. Today it is possible to reduce or remove air pollutants by making combustion, conversion, or collection of industrial exhaust and emissions.

The primary devices for managing air pollution that are best suited for industrial uses consist of the following:

  • biofilters are devices used to control air pollution, operating on the principle of utilizing microorganisms, such as bacteria or fungi, which eliminate water-soluble substances;
  • air filters employ a specific filtration media (fabric, sintered metal, ceramic, etc.) that enables collection and removal of dry particulates and contaminants in residential, commercial, and industrial fields of applications;
  • cyclones can separate dry particulates from gaseous exhausts by centrifugal force that makes large particulates drop into the collection hopper;
  • electrostatic precipitators are used for the collection of particulate matter by a high static electrical impulse that attracts the particulate to the collecting plates;
  • mist collectors are the perfect way to remove moisture and vapor, for example, smoke, oil, mist, etc. – from gas streams by the use of fine mesh-like filters that collect liquid droplets;
  • incinerators help to maintain air quality by the employment of combustion techniques to transform pollutants into non-toxic byproducts;
  • catalytic reactors are effective for air pollution control that is commonly used for the removal of NOx emissions due to the reaction between injected into industrial emissions ammonia and the NOx compounds;
  • scrubbers.

Scrubbers are the most popular air pollution control devices that are highly used in manufacturing and processing facilities. Scrubbers remove particulates and gases from industrial emissions before they are released into the atmosphere. Now there are two main types of scrubbing systems:

  • dry scrubbers that remove air pollutants and neutralizing the acidity of the emissions with the help of special chemical agents;
  • wet scrubbers use liquid solutions (typically water) for the collection and removal of water-soluble gas and particulate pollutants from industrial emissions. Wet air scrubbing is the most efficient way for air pollution control and an increase in air quality.

If you are looking for the best air treatment device to improve air quality, Redwood Technology offers a cutting-edge type of wet scrubber – a Multi-Vortex wet air scrubber.

Redwood technology is a fast-growing vendor of wet air scrubbers. The multi-vortex scrubber can remove gas emissions, dust, vapors, and other pollutants from a gas stream. It is an innovative technology created to save water that makes it more cost-efficient and differs from other types of scrubbers.  If you have any questions or would like to purchase a multi-vortex wet air scrubber, please contact us at info@rdwd.tech
