wet scrubber
Quick Summary
A wet scrubber is a technology used in air pollution control to remove suspended particles and gases from an airstream. It works by spraying water or another liquid into the dirty air, causing pollutants to collide with and be captured by the liquid droplets. Different configurations exist, such as spray towers, orifice scrubbers, and Venturi scrubbers, with Venturi scrubbers being the most efficient for trapping fine particles. Wet scrubbers are also employed for gas absorption, where a liquid solvent or reactant captures gaseous pollutants. They are commonly used in industrial settings like power plants and chemical facilities to reduce harmful emissions.12

Devices called wet scrubbers trap suspended particles by direct contact with a spray of water or other liquid. In effect, a scrubber washes the particulates out of the dirty airstream as they collide with and are entrained by the countless tiny droplets in the spray.
