Explanation:Purification of water on a large scale!

Water is purified on a large scale in establishments that are known as waterworks.

1. Sedimentation:

Water pumped from the source (river, lake or dam) is allowed to stand in large tanks, called settling tanks, for a few hours. Mud, sand and other suspended particles settle down. The addition of a small quantity of potash alum helps the suspended particles to settle down quickly.

2. Filtration: The water from the sedimentation tank is filtered through layers of sand and gravel. Filtration is also done through activated charcoal, which affords better-quality water by holding impurities strongly .

3. Chlorination:

The filtered water is then treated with chlorine gas, which kills germs.
