Wet Scrubber

A wet scrubber or wet scrubber system is one type of Scrubber that is used to remove harmful materials from industrialexhaust gases known as flue gas before they are released into the environment. It was the original type of scrubbing system, andutilizes a wet substance to remove acidic gases that contribute to acid rain. When using a wet scrubber, flue gas is funnelled through an area and sprayed with a wet substance. Water is used when dustand particular matter is to be removed, but other chemicals can be added. These chemicals are chosen to specifically react withcertain airborne contaminants—generally acidic gases. This process adds significant amounts of vapour to the exhaust—whichcauses the release of exhaust that appears as white smoke when vented. One reason for the development of dry scrubbing was because the sprayed water added considerable weight and volume to thewaste, which led to difficulties in storing and disposing of the waste material.
