Describe the steps involved in getting clarified water?
Treatment of wastewater involves physical, chemical, and biological processes, which remove physical, chemical and biological matter that contaminates the wastewater.​

Following steps are involved:
1. Wastewater is passed through bar screens which remove large objects like rags, sticks, cans, plastic packets, napkins etc.
2. Water then goes through Grit and Sand removal tank, where sand, grit and pebbles settle down.
3. Water is then allowed to settle in a tank where solids like faeces (called sludge) settle at the bottom and are removed with a scraper. A skimmer removes the floatable solids like oil and grease. Water so cleared is called clarified water. Sludge is used to produce biogas.
4. Clarified water is then passed through an aerator tank where air is pumped into the water. It helps aerobic bacteria to grow which decompose organic matter like human waste.
5. After several hours, the suspended microbes settle at the bottom of the tank as activated sludge. The water is then removed from the top. The dried activated sludge is used as manure.
6. Water is removed from the top and is stored in a tank. The treated water has low level of organic material and suspended matter. It is discharged into a sea, a river or into the ground. Sometimes it is disinfected through chemicals like Chlorine and ozone and then distributed to towns.

Describe the steps involved in getting clarified water?

Steps to Get Clarified Water:

1. Filtration:
- The first step in getting clarified water is filtration. This involves passing the water through a series of filters to remove large particles, debris, and impurities. The filters may include sand, gravel, activated carbon, or ceramic membranes.

2. Sedimentation:
- After filtration, the water undergoes sedimentation. During this process, the water is left undisturbed in a tank or basin, allowing suspended particles to settle at the bottom. The clear water is then carefully decanted or siphoned off, leaving behind the settled particles.

3. Coagulation:
- Coagulation is the next step in the process of clarifying water. Chemical coagulants such as aluminum sulfate or ferric chloride are added to the water to destabilize suspended particles and allow them to clump together. These particles form larger, easier-to-remove flocs.

4. Flocculation:
- Flocculation involves gently stirring the water to encourage the formation of larger flocs. This helps the particles to come together and settle out more easily during the next step of the process.

5. Clarification:
- Once the flocs have formed, the water is allowed to settle again. The flocs settle at the bottom of the tank, leaving clear water at the top. This clear water is then carefully removed, leaving behind the settled particles.

6. Disinfection:
- The final step in the process of getting clarified water is disinfection. This involves the addition of chlorine or other disinfectants to kill any remaining bacteria, viruses, or other harmful microorganisms. This ensures that the water is safe for consumption.

By following these steps, water can be effectively clarified and made safe for drinking and other uses.
