What is the SODIS method of water purification?

What is the SODIS method of water purification?

SODIS method: Solar water disinfection also known as SODIS is a method of water purification that uses solar energy to make biologically-contaminated (e.g. bacteria, viruses, protozoa and worms) water safe to drink.

What is SODIS method?

SODIS, Solar water disinfection is a simple method to. improve the quality of drinking water by using sunlight to. inactivate pathogens causing diarrhoea. Contaminated. water is filled into transparent plastic bottles and.

What is the purpose of SODIS?

In the laboratory, SODIS has been proven to inactivate the viruses, bacteria, and protozoa that cause diarrheal diseases. Field data have also shown reductions of viruses, bacteria, and protozoa in water from developing countries treated with SODIS.

Why is SODIS used in school to treat water?

In SODIS, recycled transparent plastic drinks bottles containing contaminated water are exposed to full sunlight for 6 hours. During this exposure, ultraviolet radiation from the sun, together with an increase in temperature, inactivates the disease-causing organisms in the water.

What are the four methods to purify 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.

Can the Sun sanitize water?

Solar disinfection uses the sun’s ultraviolet (UV) rays to kill microorganisms in water. When a sealed, clear container of water is exposed to sunlight, the UV radiation destroys bacterial, viral, and parasitic pathogens.

Which UV light Cannot be used to apply SODIS?

Ordinary window glass is almost opaque to UV light and cannot be used to construct SODIS containers.

Can sunlight sanitize water?

What are 3 ways to purify water?

Three Ways To Purify Water

  1. Boiling. Bring the water to a rolling boil for 3-5 minutes. Let cool before drinking.
  2. Disinfect. You can use household liquid bleach (regular household bleach contains 5.25% sodium hypochlorite) to kill microorganisms.
  3. Distillation. Fill a pot halfway with water.
