A wet scrubber system is an air pollution control device used to remove pollutants, such as particulate matter, gases, and vapors, from exhaust streams by passing the air through a scrubbing liquid, typically water or a chemical solution. Wet scrubbers are vital in industries like chemical manufacturing, power generation, mining, and wastewater treatment to reduce harmful emissions and ensure compliance with environmental regulations.
