How can you make drinking water safe?
If you don’t have safe bottled water, you should boil your water to make it safe to drink.
Boiling is the surest method to kill disease-causing organisms, including viruses, bacteria, and parasites..
What is water treatment?
Water treatment is any process that improves the quality of water to make it appropriate for a specific end-use. The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment.
What are the 5 stages of water treatment?
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 are the conventional methods of water treatment?
What is the Conventional Method to Treat Water? Many water treatment plants use a combination of coagulation, sedimentation, filtration and disinfection to provide clean, safe drinking water to the public.
What two chemicals are commonly used as water coagulants?
Aluminum sulfate (alum) is the most common coagulant used for water purification. Other chemicals, such as ferric sulfate or sodium aluminate, may also be used. Coagulation is usually accomplished in two stages: rapid mixing and slow mixing.
Do water treatment plants remove chemicals?
New research shows that wastewater treatment plants that employ a combination of purifying techniques followed by reverse osmosis – a process by which water is forced through a barrier that only water can pass – do a good job of removing chemicals that may elicit health effects.
What is the first step of raw water treatment?
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.
How is city water treated?
Filtration – The clear water on top passes through filters composed of sand, gravel and charcoal to remove dissolved particles such as dust, parasites, bacteria, viruses and chemicals. Disinfection – Chlorine or chloramine is added to kill parasites, bacteria, viruses and germs.
