Wet Scrubber Systems / Wet Scrubbing Systems
Wet Scrubber Systems are highly effective air pollution control devices designed to remove
contaminants such as dust, gases, and chemical pollutants from industrial exhaust streams.
These systems use liquid—typically water or chemical solutions—to capture and neutralize
pollutants before they are released into the atmosphere. Wet scrubbers are widely used in
industries such as power plants, chemical manufacturing, pharmaceuticals, food processing,
and metal processing to comply with environmental regulations and maintain air quality.
The working principle of a wet scrubber involves bringing polluted gas streams into direct
contact with the scrubbing liquid. As the gas passes through the scrubber, the liquid
absorbs or reacts with harmful pollutants, effectively trapping particulates, acidic gases
(such as sulfur dioxide, hydrogen chloride, and ammonia), and volatile organic compounds
(VOCs). Depending on the application, different types of wet scrubbers are used, including
spray towers, venturi scrubbers, packed bed scrubbers, and impingement plate scrubbers.
Venturi scrubbers, for example, are highly efficient in capturing fine particulates due to
their high-velocity gas-liquid interaction, whereas packed bed scrubbers use specialized
packing materials to maximize the gas-liquid contact area for efficient pollutant removal.
Wet scrubbers offer several advantages, including high removal efficiency for both gaseous
and particulate pollutants, the ability to handle high-temperature gas streams, and
flexibility in treating multiple pollutants simultaneously.
