Absorption technologies refer to methods used to capture and remove substances from gases or liquids. These technologies are commonly employed in various industries, including environmental engineering, to control pollution and improve air quality. They work by allowing a target substance to be absorbed into a liquid or solid material, effectively separating it from the surrounding environment. One popular application of absorption technologies is in scrubbers, which are devices that remove harmful pollutants from industrial exhaust gases. Another example is the use of absorbent materials in water treatment processes, where contaminants are captured to ensure clean and safe water for consumption.
