What are the 3 main steps taken to treat water at a treatment plant?

Water treatment

  • Sedimentation – the water is stored in a large tank or a reservoir.
  • Filtration – the water is sprayed onto specially-prepared layers of sand and gravel.
  • Chlorination – chlorine gas is injected into the water to sterilise it.

What is the process of treating water?

Coagulation and flocculation are often the first steps in water treatment. After the water has been filtered, a disinfectant (for example, chlorine, chloramine) may be added in order to kill any remaining parasites, bacteria, and viruses, and to protect the water from germs when it is piped to homes and businesses.

What is water treatment process?

Water treatment is any process that improves the quality of water to make it appropriate for a specific end-use. Water treatment removes contaminants and undesirable components, or reduces their concentration so that the water becomes fit for its desired end-use.

Which of the following lists the steps of water treatment in the correct order?

The correct order is: coagulation, sedimentation, filtration, and disinfection.

How many steps are in the water treatment process quizlet?

12 Steps of Water Purification.

What are the main steps used in sewage treatment?

Treatment Steps

  • Step 1: Screening and Pumping.
  • Step 2: Grit Removal.
  • Step 3: Primary Settling.
  • Step 4: Aeration / Activated Sludge.
  • Step 5: Secondary Settling.
  • Step 6: Filtration.
  • Step 7: Disinfection.
  • Step 8: Oxygen Uptake.

What are the two processes involved in water treatment?

The processes involved in removing the contaminants include physical processes such as settling and filtration, chemical processes such as disinfection and coagulation, and biological processes such as slow sand filtration.

What is the first step in the water treatment process?

Coagulation and flocculation are often the first steps in water treatment. Chemicals with a positive charge are added to the water. The positive charge of these chemicals neutralizes the negative charge of dirt and other dissolved particles in the water.
