How are air pollution emissions controlled?
These emissions are typically controlled to high efficiencies using a wide range of air pollution control devices. The selection of the appropriate control technology is determined by the pollutant collected, the stationary source conditions, and the control efficiency required.
What devices are used to control particulate emissions?
The most commonly used devices for controlling particulate emissions include: • electrostatic precipitators (wet and dry types), • fabric filters (also called bag houses), • wet scrubbers, and • cyclones (or multiclones).
What Wet collection devices are used for PM control?
Wet collection devices used for PM control include venturi scrubbers, bubbling scrubbers, spray towers, and in some instances, wet electrostatic precipitators (ESPs).
What are the sources of air pollution?
Stationary sources of air pollution emissions, such as power plants, steel mills, smelters, cement plants, refineries, and other industrial processes, release contaminants into the atmosphere as particulates, aerosols, vapors, or gases.
