Which of the following is the primary purpose of scrubbers in pollution control?

The primary purpose of scrubbers in pollution control is to wash and absorb pollutants. Scrubbers are devices used in industrial processes to remove harmful substances from exhaust gases before they are released into the atmosphere. By utilizing a liquid medium, scrubbers can effectively capture and dissolve various contaminants, such as sulfur dioxide, particulate matter, and volatile organic compounds, thereby reducing air pollution and ensuring compliance with environmental regulations.

While separating gases, compressing air, and measuring air quality are crucial elements in managing environmental aspects, they do not represent the main function of scrubbers. Instead, these devices are specifically designed to interact with pollutants directly, providing a vital service in the quest for cleaner air and promoting healthier environments.
