Traditionally, the term " scrubber " has referred to pollution control devices that use liquid to wash unwanted pollutants from a gas stream. Recently, the term has also been used to describe systems that inject a dry reagent or slurry into a dirty exhaust stream to "wash out" acid gases. Learn what a scrubber is, how it works, and what are its main components. Explore different types of scrubbers, such as wet, dry, electrostatic, and gas absorption, and their applications in various industries. In a wet scrubber process air is drawn through a mist of water made by spray nozzles, then through separators where water droplets with dust and particles are removed. Advantages of Wet Scrubber Versatile applications: Wet Industrial scrubbers can remove a host of contaminants, including both gases and particulate matter. Wet Industrial scrubbers are also a good choice for handling high-temperature, high-humidity gas streams, unlike ESPs and some other types of filtration systems.
