Answer 1

Answer:

The process of water treatment is mentioned below in detail:

Explanation:

• First of all the heavy wastage like rags and sticks are taken out from the screen so that it doesn't damage the pipes and other internal machine parts.
• Now the water is passed into grit chamber. Here water contaminated by sand, stones etc. is settled at the bottom of the tank.
• After screening and grit chamber,the water still contains the organic and inorganic waste.
• The pumping process in the sedimentation tank pumps out the bio solids.
• Finally using bacteria removes 80% of the organic waste.
