A wet scrubber, also known as a wet scrubber system or simply a scrubber, is an air pollution control device used to remove pollutants, such as particulates, gases, and chemical compounds, from industrial exhaust gases or emissions. It does this through a process known as “scrubbing,” which involves the interaction of the contaminated gas stream with a liquid (usually water or a chemical solution) to capture and remove the pollutants. Wet scrubbers are commonly used in various industries to improve air quality and reduce emissions.
