What does a scrubber do in relation to air pollution?

A scrubber, particularly in the context of air pollution control, serves the purpose of reducing pollutants in industrial exhaust gases. Scrubbers operate by moving flue gases through a spray of water or a chemical solution, which helps to capture and neutralize harmful substances, such as sulfur dioxide, particulate matter, and other gaseous pollutants. The process typically involves the absorption of these pollutants into the liquid, effectively removing them from the gas stream before it is released into the atmosphere.

This method is particularly significant for industries that generate significant amounts of gaseous pollutants, as it plays a crucial role in meeting environmental regulations and minimizing the harmful impact of these emissions on air quality and public health. The correct understanding of a scrubber's function highlights its importance in air pollution control technologies.
