Solar Disinfection Methods
To purify water when you're away from modern conveniences, solar disinfection—or SODIS—is a fantastic method. Here's how it works: fill clear PET or glass bottles with water and set them out in direct sunlight. The magic happens thanks to the sun's UV rays, which neutralize harmful microorganisms lurking in the water.
Why clear bottles, you might ask? It's crucial because the clarity allows UV rays to penetrate through the water effectively. Not only do these rays zap microbial cells, but they also spark the creation of reactive oxygen forms that help break down other pollutants.
For the best results, you should let the water sit in the sunlight for at least six hours under sunny skies. If it's partly cloudy, though, you'll need to extend this period to about two days to ensure all pathogens are destroyed. Also, remember to lay the bottles horizontally to expose more water surface to the sunlight.
For example, you might use a typical 1-liter clear PET bottle, like those used for drinking water, which are readily available and inexpensive. This makes SODIS an accessible option for many people, especially in remote areas.
This method isn't only simple but also effective in making your drinking water safe. So next time you find yourself needing clean water in an off-grid situation, give SODIS a try with some clear bottles and a sunny spot!
