What are the four stages of water treatment?
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.
- Filtration.
- Disinfection.
How does a water treatment system work?
As sewage enters a plant for treatment, it flows through a screen, which removes large floating objects such as rags and sticks that might clog pipes or damage equipment. After sewage has been screened, it passes into a grit chamber, where cinders, sand, and small stones settle to the bottom.
Where does the water go once it is treated?
The treated wastewater is released into local waterways where it’s used again for any number of purposes, such as supplying drinking water, irrigating crops, and sustaining aquatic life.
How does a treatment plant work?
Using internal mechanisms, a sewage treatment plant works by breaking down solid waste to produce a cleaner, more environmentally friendly effluent. Wastewater and sewage are supplied to the primary tank, where the solids and liquids disperse.
What is the best method of water purification?
Here are some of the most effective water purification methods that have stood the test of time:
- Boiling. The simplest method to purify water is to boil it for a good time.
- Water Purifier.
- Reverse Osmosis.
- Water Chlorination.
- Distillation.
- Iodine Addition.
- Solar Purification.
- Clay Vessel Filtration.
