Scrubber

Scrubber systems 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 Ictineo I, a role for which they continue to be used to this day. Traditionally, the term "scrubber" has referred to pollution control devices that use liquid to wash unwanted pollutants from a gas stream. Recently, the term is also used to describe systems that inject a dry reagent or slurry into a dirty exhaust stream to "wash out" acid gases. Scrubbers are one of the primary devices that control gaseous emissions, especially acid gases. Scrubbers can also be used for heat recovery from hot gases by flue-gas condensation.

There are several methods to remove toxic or corrosive compounds from exhaust gas and neutralize it.

Combustion

Combustion is sometimes the cause for harmful exhaust, but, in many cases, combustion may also be used for exhaust gas cleaning if the temperature is high enough and enough oxygen is available.

Scrubber (brush)

A scrubber (German: Schrubber), is a type of wide brush with a long shaft used for cleaning hard floors or surfaces. Unlike a broom, which has soft bristles to sweep dirt away, a scrubber has hard bristles for brushing. It may therefore be used wet, with water or cleaning fluids. Around the brush head there may also be a removable floorcloth or mop, either soaked in water for cleaning or dry for wiping dry. However, these days other cleaning implements tend to be used for such purposes.

In North Germany and in sailor's language, a scrubber is also called a Leuwagen, hence in large firms or offices a cleaning party is sometimes jokingly called a Leuwagenballett ("scrubber ballet").
