A scrubber is an air pollution control device used to remove harmful pollutants, typically found in industrial emissions, before they are released into the atmosphere. It operates by passing the contaminated air through a liquid or slurry, which captures and neutralizes the pollutants. This process primarily targets acidic gases like sulfur dioxide and harmful particulates, preventing their release into the environment. Scrubbers play a crucial role in reducing air pollution and protecting public health, as well as ensuring regulatory compliance for industrial facilities. They are a key component in the effort to minimize the environmental impact of various manufacturing processes.
