Wet scrubbers are air pollution control devices that use liquid to remove harmful particles and gases from industrial exhaust. They work by passing the polluted air through a spray of liquid, usually water or a chemical solution, which captures the contaminants. This process helps reduce emissions and improve air quality. These systems are commonly used in industries such as power generation, chemical manufacturing, and waste management. Wet scrubbers can effectively remove pollutants like sulfur dioxide and particulate matter, making them an essential tool for meeting environmental regulations and protecting public health.
