Solar energy is used in many sectors to enhance efficiency and achieve sustainability. Businesses and homeowners are harnessing solar energy to reduce dependence on the power grid.
There is a sector in which solar energy is of great use. It is helping in saving lives and improving life quality. And that is the utilization of solar energy for water purification.
In this blog, we’ll discover how solar power can help in water purification in remote areas.
What is SODIS: Solar water disinfection?
Solar water disinfection or SODIS, is an effective method of purifying water. This is achieved by powering distillation systems with sunlight.
The process involves filling transparent plastic bottles with water and exposing them to direct sunlight for several hours. The UV-A radiation in sunlight kills the microorganisms, making it safe to drink. SODIS is particularly useful in remote areas where access to clean water sources and traditional purification methods is limited. The benefits of SODIS are:
- improves the microbiological quality of drinking water
- does not change the taste of water
- is applicable at the household level and in remote areas
- is simple in application
- relies on local renewable energy
- is replicable with low investment costs
There is another mechanical system where we use solar energy for water purification.
Solar water purification: A mechanical system
Solar water purification is an eco-friendly method of obtaining safe drinking water. It involves using solar power to heat water and eliminate harmful pathogens.
The process typically includes the use of solar stills or solar distillation systems. These systems use the sun’s energy to heat the water. The water is evaporated and then condensed as purified water.
Solar water purification is a reliable and cost-effective solution for remote areas. With initial investment, they can generate purified water for decades to come.
Benefits of Solar-Powered Water Purification Systems
Solar-powered water purification systems offer several advantages:
– They are sustainable and environmentally friendly. They rely on renewable solar energy reducing the energy cost.
– They provide a reliable source of clean drinking water in remote areas. This results in reducing the risk of waterborne diseases.
– They are cost-effective in the long run, as they require minimal maintenance and no fuel or electricity costs.
– They can be easily installed and operated, making them accessible to communities in need.
