What is the process of water purification?
There are several methods used in the water purification process, which include: (1) physical processes, such as filtration, sedimentation, or distillation; (2) biological processes, such as sand filters, active carbon; (3) chemical processes, such as flocculation, chlorination, the use of ultraviolet light.
What are the methods of purification of water?
4 Methods to Purify Your Water
- 1 – Boiling. Boiling water is the cheapest and safest method of water purification.
- 2 – Filtration. Filtration is one of the effective ways of purifying water and when using the right multimedia filters it’s effective in ridding water of the compounds.
- 3 – Distillation.
- 4 – Chlorination.
How many steps are there in water purification?
In wealthier countries, illness and death from water contamination are far rarer because of wide-scale, mostly government-operated water purification systems. Although these water treatment systems vary, many safeguard public health through an eight-step purification process.
What are the 7 stages of water filtration?
The Seven Steps Of The Water Purification Process
- ION Exchange and Coagulation. This is the first step of the purification process.
- Sedimentation.
- Filtration and Granular Activated Carbon.
- Disinfection.
- Carbon Filters.
- Reverse Osmosis.
- Store Purified Water.
What is the main process to purify water by filtration?
Sludge forms that appear on the floor of the tank are removed and treated. From that basin, water is moved to the next step, filtration, which removes the remaining suspended particles and unsettled floc in addition to many microorganisms and algae. Disinfection is the final step in water purification.
Which is the correct sequence for water purification?
The water-treatment process involves four steps, in this order: coagulation, sedimentation, filtration, and disinfection.
How does municipality clean water?
The most common disinfection process used is chlorination. Chlorine comes in many different forms, including chlorine gas (the most common), chlorine dioxide and hypochlorite. Whichever method is used, chlorine is added to the water in a quantity to ensure that most, if not all, viruses and bacteria are destroyed.

How does a municipal water treatment system work?
The municipal water treatment methods used will depend on whether this is a hard-water area, cost, and any quality requirements that need to be in place. Coagulation and flocculation work by clumping particles and solids together by introducing chemicals like aluminum sulfate or iron that cause all contaminants to give off a positive charge.
What’s the best way to clean municipal water?
Wastewater chlorination is the most common method of disinfection used in municipal water systems. This needs to be done by highly skilled technical engineers to ensure the correct levels of chlorination are maintained. Ozone is another method used by passing oxygen through ultraviolet light.
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,…
