Wet Scrubber System
- WET SCRUBBER SYSTEMS
A Wet Scrubber System is an effective air pollution control device that removes gases, vapors, and particulate matter from industrial exhaust streams. The process involves intimate contact between the polluted gas and scrubbing liquid, typically water or a chemical solution, which absorbs and neutralizes harmful contaminants. Wet scrubbers are widely used in industries that emit acidic gases, fumes, or high particulate loads.
- How It Works
- Polluted gas stream enters the scrubber chamber.
- A scrubbing liquid (water/alkaline/chemical solution) is sprayed or circulated.
- Gas pollutants dissolve or react with the liquid, while particulates are captured.
- Cleaned gas exits from the top, and contaminated liquid is collected for treatment.

- Comparison: Wet Scrubber vs. Cyclone Separator
| Parameter | Wet Scrubber | Cyclone Separator |
|---|---|---|
| Pollutants Removed | Gases + fine particulates | Mainly coarse particulates |
| Efficiency | Very high (90–99%) | Moderate (70–95%) |
| Maintenance | Requires handling of wastewater/chemicals | Minimal, almost maintenance-free |
| Operating Cost | Higher due to pumps & water usage | Very low |
| Temperature Handling | Can handle hot, humid, and corrosive gases | Handles hot gases but limited for corrosive |
