Types of air pollution control equipment

Air pollution is the most crucial problem of today modern society that requires an urgent solution. Herewith, the sources of air pollution can be both natural for example, volcanic eruptions and wildfires and human-made (mobile and stationary ones). Thus, air pollution control remains the only way of air treatment.

Also, it should be noted that every industrial process produces different air pollutants, that is why there are several types of air pollution control equipment for both mobile and stationary sources from various kinds of industries. Nowadays it is possible to reduce or remove air pollutants by making combustion, conversion or collection of the industrial exhaust and emissions.

Traditionally, the most common devices for air pollution control which are ideally suited for industrial applications include the following:

  • biofilters are air pollution control equipment which principle of operation is based on the use of microorganisms, for example, bacteria or fungi that remove water-soluble compounds;
  • air filters employ a specific filtration media (fabric, sintered metal, ceramic, etc.) that enable to collect and remove dry particulates and contaminants in residential, commercial, and industrial fields of applications;
  • cyclones are able to separate dry particulates from gaseous exhausts by centrifugal force that makes large particulates drop into the collection hopper;
  • electrostatic precipitators are used for collection of particulate matter by a high static electrical impulse that attracts the particulate to the collecting plates;
  • mist collectors are the perfect way for removal of 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 a quite effective technique of air pollution control that is commonly used for 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 take away 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 allow removing air pollutants and neutralizing the acidity of the emissions with the help of special chemical agents;
  • wet scrubbers used liquid solutions (typically water) for the collection and removal of water-soluble gas and particulate pollutants from industrial emissions. Herein, at the present time, wet air scrubbing is the most efficient way for air pollution control and an increase in air quality.
