Answer 1

Answer:

Clarified water is water which has undergone clarification to remove suspended solids and solid particles. Water clarification is used in the pre-treatment of drinking water, prior to further purification, and the treatment of municipal wastewater and industrial effluent.

FOLLOWING STEPS ARE INVOLVED IN PURIFICATION OF WATER:

• Firstly all the physical impurities like stones, plastic bags, cans, etc... are to be removed. It is done by passing the water through bar screens.
• Then water is taken to grit and sand removal tank where impurities are removed by sedimentation.
• Solid impurities and faeces etc are collected from the bottom of the water.
• These impurities collected are called sludge.
• Clarified water is cleaned of other impurities bye the aerator. All the disease-causing bacteria are removed by chlorination.
