Answer: B
A wet scrubber treats air pollution.
In a wet scrubber the polluted gas stream is brought into contact with a scrubbing liquid, usually water or an alkaline solution, by spraying, bubbling or passing through packing. Particles are captured in the droplets and soluble gases such as sulphur dioxide, hydrogen chloride and ammonia are absorbed, so it controls both particulate and gaseous emissions from stacks.
It produces wastewater rather than treating it, and it has nothing to do with soil remediation or noise control.
