Wet Scrubber A wet scrubber is an air pollution control device that removes contaminants, such as particulates and gaseous pollutants, from industrial exhaust streams by using a liquid, typically water. The scrubbing liquid interacts with the polluted air, capturing impurities through absorption, condensation, or chemical reactions. Wet scrubbers are highly effective in treating exhaust from processes in industries such as power generation, chemical manufacturing, and metal processing. Depending
