Wet and Dry Scrubbers: Types, Benefits, Innovations, and Choosing the Right System

What Are Wet and Dry Scrubbers?

Wet and dry scrubbers are devices used to clean air and gases. They help remove harmful substances from emissions before they go into the atmosphere. Wet scrubbers use liquid to capture particles and gases. In wet scrubbers, dirty air passes through a spray of water or a chemical solution. This liquid traps the pollutants. The clean air then moves out of the scrubber.

Dry scrubbers use a different method. They use solid materials, like powders or granules, to clean the air. In dry scrubbers, the dirty air flows through these materials. The solids stick to the pollutants and remove them from the air.
