A wet scrubber is a device that is used for trapping the emissions of water-soluble gases such as sulphur dioxide, nitrogen oxide, and ammonia.
- In a wet scrubber, spray nozzles are fitted through which water is sprayed into the device in a way that it goes downwards.
- As polluted gases rise upwards, their particulate matter collides with water drops. Because of the gravitational force, the water drops containing particulate matter settle at the bottom and the pollutants are segregated.
