Which of the following options best describes the primary function of a scrubber in the context of air pollution control from industrial emissions?
- Scrubbers are electrostatic devices that remove particulate matter from industrial exhausts to prevent its release into the atmosphere.
- Scrubbers utilize a high-speed air flow to separate harmful gases, such as nitrogen and oxygen, from industrial emissions before their release.
- Scrubbers reduce the concentration of harmful particulate matter smaller than 2.5 micrometers in diameter, effectively mitigating their detrimental effects on human health.
- Scrubbers use a spray of water or lime to eliminate gases like sulfur dioxide from industrial exhausts before their dispersal into the environment.
