What are the steps in water treatment?

What are the steps in water treatment?

They typically consist of several steps in the treatment process. These include: (1) Collection ; (2) Screening and Straining ; (3) Chemical Addition ; (4) Coagulation and Flocculation ; (5) Sedimentation and Clarification ; (6) Filtration ; (7) Disinfection ; (8) Storage ; (9) and finally Distribution.

What is the first step in the water process?

Step 1: Evaporation The water cycle begins with evaporation. It is a process where water at the surface turns into water vapors. Water absorbs heat energy from the sun and turns into vapors. Water bodies like the oceans, the seas, the lakes and the river bodies are the main source of evaporation.

How do you treat river water?

Boiling is the best way to kill disease-causing organisms, including viruses, bacteria, and parasites. The high temperature and time spent boiling are very important to effectively kill the organisms in the water. Boiling will also effectively treat water if it is still cloudy or murky.

What is the first step in water treatment plant?

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.

What are the 3 stages involved in treating water?

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 are the main treatment steps in a water treatment plant to treat river water?

1. Coagulation.
2. Coagulation-Flocculation.
3. Flocculation.

What are the 5 steps of water treatment plant?

The 5 major unit processes include chemical coagulation, flocculation, sedimentation, filtration, and disinfection (described below).

What is the order of the water cycle?

There are four main stages in the water cycle. They are evaporation, condensation, precipitation and collection.

What are the two main steps used to treat water from lakes?

Coagulation and flocculation are often the first steps in water treatment.

What are the two main steps to treat water from lakes?

Community Water Treatment

1. Coagulation and Flocculation. Coagulation and flocculation are often the first steps in water treatment.
2. Sedimentation. During sedimentation, floc settles to the bottom of the water supply, due to its weight.
3. Filtration.
4. Disinfection.

Which is the first step in the wastewater treatment process?

The process is mainly initiated at the treatment plant. This is done by containing the wastewater and treating it with chemicals. This chemical will automatically neutralize the smell producing elements. This is one of the most important process that you will not miss. Screening is the next step in the wastewater treatment process.

What do you need to know about water treatment?

Water Treatment 1 Community Water Treatment. Drinking water supplies in the United States are among the safest in the world. 2 Water Fluoridation. Community water fluoridation prevents tooth decay safely and effectively. 3 Consumer Confidence Reports. 4 Household Water Treatment.

What’s the next step in the water purification process?

Dip your bottle just under the surface and fill from there. The next step in the water purification process is filtration. Filtration by itself does not purify water. It must be followed by boiling or disinfection to purify water for drinking.

What is the process of community water treatment?

Community Water Treatment. Sedimentation During sedimentation, floc settles to the bottom of the water supply, due to its weight. This settling process is called sedimentation. Filtration Once the floc has settled to the bottom of the water supply, the clear water on top will pass through filters of varying compositions (sand, gravel,…
