Answer 2

Answer: Filtration

Explanation:

Filtration is a physical process that helps us separate the suspended solid particles in a liquid. When water is passed through beds of granular materials it gets filtered out and the suspended solid particles get separated from the liquid.

Very fine suspended particles can also be removed by filtration. It also helps in removing pathogenic bacteria from water.

The water that undergoes screening, sedimentation and coagulation may still contain fine suspended particles. Therefore, it needs to undergo filtration for removing them.
