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 two processes responsible for purifying the water?
The key terms are evaporation and condensation. Evaporation is defined as the process through which a liquid becomes a vapor. Condensation is the process through which a vapor becomes a liquid, and is the opposite of evaporation.
What is the process of natural water purification?
Natural purification effects within filter layers and in the subsurface are caused mainly by filtration, sedimentation, precipitation, oxidation-reduction, sorption-desorption, ion-exchange and biodegradation.
What is used in treatment for water purification?
Chlorination is the most common form of disinfection. Chlorine is a strong oxidant, and rapidly kills many microorganisms, especially bacteria. Because chlorine is a toxic gas, it can also be dangerous to sanitation workers. Chlorine based compounds like choloramine are often used.
Does condensation purify water?
As a result, when the water vapor condenses to become water again, it is relatively pure. The evaporation and condensation are the key terms that help water purifying. While these processes occur during the water cycle, it can also be used to purify water for drinking or industry use. Water is always moving.
Which non metal is used in water purification process?
Chlorine is a non-metal which is used to disinfect water. Chlorine can be applied for the deactivation of most microorganisms like bacteria.
What are the four methods to purify water?
4 Methods to Purify Your Water

What things can filter water?
Natural Materials Used for Water Filtration
- Sand. The use of sand for water filtration dates back 2,000 years. …
- Oysters. Oysters naturally filter toxins when they feed. …
- Plants. Plants are a natural choice for water filtration, especially in wetland areas. …
- Charcoal. Charcoal is a slow, but effective, water filter. …
How can we purify river water naturally?
Boiling: Boiling is the best way to kill disease-causing organisms, including viruses, bacteria, and parasites. The high temperature and time spent boiling are very important to effectively kill the organisms in the water. Boiling will also effectively treat water if it is still cloudy or murky.
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.
Why is purifying water important?
One major purpose of water purification is to provide clean drinking water. … The purification procedure reduces the concentration of contaminants such as suspended particles, parasites, bacteria, algae, viruses, and fungi.
How do you purify groundwater?
Through the usage of straw filters we can reduce the concentration of iron in the subtracted groundwater. The iron is brought in contact with oxygen by letting the water fall freely into a container.
- Influent tank.
- Sand filter.
- Effluent tank.
- Flushing buffer.
- Control units.
- Process pumps.
Is it safe to drink condensed water?
A process that condenses water from air will also entrain some of the contaminants in the concentrate, so it is necessary to clean the water that has been condensed before it can be consumed as drinking water. The principal contaminants of concern are usually the microbial components, some of which could be pathogens.
Is condensation safe to drink?
Water collected from an air conditioner is condensation pulled from the air inside your home. It should never be ingested, and is not safe to drink, as it contains traces of impurities found in the air in your home, including chemicals and heavy metals.
Why does sunlight not easily pass through dirty water?
Water transparency depends on the amount of particles in the water. These particles can be algae or sediment from erosion, the more particles – the less water transparency. In other words, when the water is murky or cloudy and contains a lot of particles, the light cannot penetrate as deeply into the water column.
