Wet scrubber is one of the air pollution control devices that can
be used to remove particle and gaseous pollutants from industrial
exhaust streams by using an absorber liquid, simultaneously. In
wet scrubbing, an atomized liquid, usually water, is used to capture
particulate dust or to increase the size of aerosols. Increasing size
facilitates separation of the particulate from the carrier gas. The
particles may be caught first by the liquid, or first on the scrubber
structure, and then washed off by the liquid
