The humidifying efficiency of the scrubber may be expressed as: μ h = (t 1 - t 2) / (t 1 - t w) (1) where. μ h = scrubber humidifying efficiency (%) t 1 = initial dry bulb temperature (o C) t 2 = final dry bulb temperature (o C) t w = initial wet bulb temperature (o C) Scrubber Efficiencies. Typical nozzle scrubber efficiencies

Scrubber systems (e.g. chemical scrubbers, gas scrubbers) are a diverse group of air pollution control devices that can be used to remove some particulates and/or gases from industrial exhaust streams. The first air scrubber was designed to remove carbon dioxide from the air of an early submarine, the Ictíneo I, a role for which they continue to be used today.
