Wet scrubbers are extremely efficient, removing up to 99% of particulates, including particulates too small to be caught in baghouse and cartridge filters.
Scrubbers with ultra-fine droplets entrap tiny particles and hold them in the solution for removal.
The original scrubber type, the wet scrubber, uses liquid to wash exhaust streams.
Dry scrubbers use dry media instead, and electrostatic precipitators use an electric charge to remove particles from the air.
