Question

State and explain the large scale use of the process of sedimentation and decantation.

Answer 1

Sedimentation and decantation processes can be used to separate grains from dirt and dust.

• Mix the mixture of grains and dirt into water.
• Now let the mixture stand for some time.
• Since, grain particles are heavy, they settle down by the process of sedimentation at the bottom while dirt will remain suspended in water.
• Now this water mixed with dirt is poured into a separate beaker by the process of decantation.
• And the grain particles are sun-dried.
• This is how grains are separated from dirt particles using the process of sedimentation followed by decantation.
