At which stage is chlorine added during water purification?
Typically, chlorine is added to public drinking water as the final stage of treatment, often following an upstream filtration step which removes sediment that can tie up chlorine and shield organisms from its effect.
What are the stages of purification of water?
THE 5 STAGES OF WATER TREATMENT
- Screening. As water enters a water treatment plant, either from lakes, rivers, or the ground, it passes through a screening.
What are the 4 processes involved in the purification of water?
Water treatment steps
- Coagulation. Coagulation is often the first step in water treatment.
- Flocculation. Flocculation follows the coagulation step.
- Sedimentation. Sedimentation is one of the steps water treatment plants use to separate out solids from the water.
What are the 7 stages of water filtration?
Seven Steps of Water Purification
- ION EXCHANGE AND COAGULATION. This is the first step of water purification process.
- FILTRATION AND GRANULAR ACTIVATED CARBON.
- CARBON FILTERS.
- REVERSE OSMOSIS.
- STORE PURIFIED WATER.
What is chlorination process?
Chlorination is the process of adding chlorine to drinking water to kill parasites, bacteria, and viruses. Different processes can be used to achieve safe levels of chlorine in drinking water.
Why is chlorine added to water during the treatment process?
Chlorine is a disinfectant added to drinking water to reduce or eliminate microorganisms, such as bacteria and viruses, which can be present in water supplies. The addition of chlorine to our drinking water has greatly reduced the risk of waterborne diseases.
Why is chlorine added to water?
Drinking water chlorination is the addition of chlorine to drinking water systems. It is the most common type of drinking water disinfection. Disinfection kills bacteria, viruses, and other microorganisms that cause disease and immediate illness.
What are stages of water?
The water cycle consists of three major processes: evaporation, condensation, and precipitation. Evaporation is the process of a liquid’s surface changing to a gas. In the water cycle, liquid water (in the ocean, lakes, or rivers) evaporates and becomes water vapor.
How much chlorine do you add to drinking water?
To disinfect water, add one part of the chlorine solution to each 100 parts of water you are treating. This is about the same as adding 1 pint (16 ounces) of the chlorine solution to 12.5 gallons of water.
What is 9 stage water filter?

What are the 7 methods of water treatment?
Top 7 Methods of Water Treatment
- Coagulation / Flocculation. Coagulation is adding liquid aluminum sulfate or alum and/or polymer to raw or untreated water.
- Sedimentation. When water and flocs undergo the treatment process, they go into sedimentation basins.
- Sludge Drying.
- pH Correction.
What is chlorine in water treatment?
As a halogen, chlorine is a highly efficient disinfectant, and is added to public water supplies to kill disease-causing pathogens, such as bacteria, viruses, and protozoans, that commonly grow in water supply reservoirs, on the walls of water mains and in storage tanks.
What is the progress in water purification?
The progress in water purification has been mainly conditioned by the scientific progress made in the identification of pathogens and other contaminants in water, the introduction of new regulations regarding water quality, but also the development of materials science, smart materials, and nanomaterials.
What are the different methods of water purification?
Aeration: Raw water is first collected in large aeration tank and the water is aerated by bubbling compressed air through perforated pipes. Aeration removes bad odors and CO2. It also removes metal such as iron, manganese by precipitating then as their respective hydroxides. 2. Storage or settling:
What is water chlorination?
Water chlorination is commonly encountered in the treatment of water supply and consists in the addition of chlorine or hypochlorite to kill microbes and to prevent the spreading of waterborne diseases.
What is the final step in wastewater treatment?
When wastes are biodegraded, production of biogas and heat occurs. A final step in wastewater treatment involves the removal of certain compounds, such as phosphorus by precipitation as, for example, insoluble iron phosphate, and of some metals by hyperaccumulating plants. Mariana Oana Mihaela Fufă,
