Solution
Scrubber
A scrubber is a device that employs a spray of water to catch pollutants during emissions. In this process, water is introduced into a spray tower by means of a spray nozzle which allows a downward flow of water. As the polluted gas flows upwards, the particulates present in the gas collide with the water droplets being sprayed from the spray nozzles. Under the influence of gravitational force, the liquid droplets containing the particulates settle at the bottom.
