How does a scrubber help in reducing the formation of acid rain?
उत्तर
A scrubber can also be used to reduce the formation of acid rain. It is a device that absorbs gaseous pollutants. It is used for removing sulphur dioxide from a smokestack and usually consists of a fine spray of water and gas rising from the stack, which is passed through the scrubber where water absorbs sulphur dioxide.
