In a wet scrubber, water or scrubbing liquid is the media which removes pollutants from the air. When the water is recirculated, addition of fresh water is necessary to purge contaminants that accumulate and to replace evaporation losses. Fresh water may be added to the recycle either continuously or periodically.
Industrial scrubbers are often used to remove acid fumes. Strong alkali is added to the recycled scrubbing solution to neutralize the acids and maintain a neutral pH.
